The invention method for making a photosensitive color change luminous film  

 
Luminous film is also called the energy storage luminescent film is a kind of using rare earth aluminate and silicate long persistence luminescent materials of plastic products, usually with pressure-sensitive adhesive from type paper as base material, the polymethyl methacrylate, polyvinyl chloride (PVC) and polyethylene terephthalate plastic as the main body of the light-emitting layer set on the base material, usually has flatten or embossed on light-emitting layer, a quick product. With the development of luminous film technology, it has been widely used in fire safety signs, ship safety signs, advertising decoration materials, craft products, children's toys and many other fields, with its long afterglow and time-delay luminescence characteristics. Because the luminous membrane surface usually choose the color is yellow-green or pale gray, special circumstances will use other non-ferrous surface, the adornment effect of the single color, usually a pure color, no decorative pattern, design, color changes, such as decorative effect, and children's toys, indoor wall decoration, handicraft production of these occasions, unable to get new decorative effect and the ideal atmosphere. As decorative materials on the market to upgrade trend with each passing day, the traditional luminescent film just rely on long afterglow time delay luminescence of the properties, in the process of competition and other decorative materials to sustain their own advantage, that there is an urgent need to have long afterglow time delay glow, as well as a beautiful, novel decoration new luminous film with surface is applied to daily decoration, handicraft and toy manufacturing.

To achieve the above purposes, the utility model provides the following technical solutions: A photosensitive discoloration of luminescent film, including printing plastic transparent protection mask layer glow, plastic film, white bottom protection, pressure sensitive rubber and from type paper layer, can be described printing plastic transparent protection mask layer at the bottom of the glow fixed connection with a plastic film layer on the surface, as described in plastic luminescence film layer on the surface at the bottom of the fixed connection with white bottom, described in white at the bottom of the protection at the bottom of the fixed connection with pressure-sensitive glue line on the surface, described from type paper layer of the sticky side surfaces connected to the bottom of the pressure sensitive rubber surface, can be described printing plastic transparent protection mask layer on the surface by spray print or uv printing decorative pattern.The printable plastic transparent protective mask layer is composed of a printable layer, an intermediate layer and a bottom layer. The bottom surface of the printable layer is fixedly provided with an intermediate layer, and the bottom surface of the intermediate layer is fixedly provided with a bottom layer.

Preferably, the intermediate layer is arranged as a high toughness layer, and the material of the high toughness layer is a high toughness plastic.The bottom layer is arranged as a laminating layer, and the material of the laminating layer is LLDPE.
Compared with the prior art, the utility model has the following beneficial effects:
1, the utility model is in use, because of luminous membrane surface set up printing plastic transparent protection layer mask, you can use uv printing or print to print for the surface of the fine decorative pattern and design, enhance the beauty of luminous film decoration, plastic light-emitting layer contains light-sensitive color pigments, photosensitive color pigment after absorb the ultraviolet ray in sunlight or artificial light, photosensitive color pigments can produce photosensitive color changing effect, change the surface color luminous film, raise the novelty decoration, printing plastic transparent protection mask layer has excellent tear resistance, is conducive to improve the performance of luminous film as a whole, makes the luminous film more durable.

The following is a clear and complete description of the technical scheme in the embodiments of the utility model in combination with the attached drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, but not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in the field without making creative labor fall within the scope of protection of the utility model.Please refer to figure 1, the utility model to implement case, a photosensitive discoloration of luminescent film, which includes printing plastic transparent protection mask layer 1, plastic light-emitting layer 2, 3 white to protect the bottom, pressure-sensitive glue line 4 and 5 from type paper layer, can be described printing plastic transparent protection mask layer 1 glow on the surface at the bottom of the fixed connection with a plastic film layer 2, described glow plastic film on the surface at the bottom of the layer 2 fixed connection with white bottom 3, described to protect the bottom 3 white surface at the bottom of the fixed connection with pressure-sensitive glue line 4, described from type paper layer may prevent sticky side surface with pressure-sensitive glue line connected to the bottom surface of the four, The plastic luminous film layer 2 is composed of energy storage luminous material and photosensitive color pigment, and the surface of the printable plastic transparent protective mask layer 1 is decorated with decorative patterns through inkjet printing or UV printing.Please refer to the figure. The printable plastic transparent protective mask layer 1 consists of the printable layer 6, the middle layer 7 and the bottom layer 8. The bottom surface of the printable layer 6 is fixedly provided with the middle layer 7, while the bottom surface of the middle layer 7 is fixedly provided with the bottom layer 8.

Please refer to the figure. The printable layer 6 is set as a transparent plastic layer, the middle layer 7 is set as a high toughness layer, the material of the high toughness layer is high toughness plastic, the bottom layer 8 is set as a laminating layer, and the material of the laminating layer is LLDPE.Working principle and use flow of the utility model: When the utility model is in use, because the luminous membrane surface set up printing plastic transparent protection mask layer 1, can use uv printing or print to print for the surface of the fine decorative pattern and design, enhance the beauty of luminous film decoration, plastic light-emitting layer 2 contain photosensitive color pigments, photosensitive color pigment after absorb the ultraviolet ray in sunlight or artificial light, photosensitive color pigments can produce photosensitive color changing effect, change the surface color luminous film, raise the novelty decoration, printing plastic transparent protection mask layer 1 has good tear resistance, is conducive to improve the performance of luminous film as a whole, makes the luminous film more durable.

End should be: the above is only for the optimization of the utility model example, are not used to limit the utility model, although in reference to the example of this utility model in detail, for the technical personnel in the field of it still can be implemented on the foregoing cases recorded by the technical scheme, modified or replace some of the technical characteristics of equivalent.
