Water-proof self-luminous printing film

Abstract

The invention provides a water-proof self-luminous printing film of the thickness of 0.150-0.156mm, and the film comprises an ink receiving layer, a connection layer, a light-storage photoluminescent film from top to bottom, wherein the ink receiving layer is prepared from inorganic stuffing, adhesive, color fixing agent, coupling agent, surfactant, cross-linking agent, fluorescent brightener and water according to certain proportion; the film has good water proofness, fast ink drying speed, clearer images after ink-jet printing and high color density and is self-luminous in the dark after absorbing external visible light; and when printed on the surface of the printing film, patterns or characters can be viewed in dark, and the film has a lighting function with low illumination. Wide application of light-storage self-luminous film products can be realized in home decoration, hotels, corridors, office buildings, cinemas, warehouses, cabins, underground passages, places needing to print a large area of high-precision patterns, and the like.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to surface materials for printing and duplication, in particular to a waterproof self-illuminating inkjet film. technical background [0002] Light storage type luminescent film is a kind of soft plastic luminescent film, which has high luminous brightness and long service life, and can be attached to the surface of various equipment and objects. It can be applied to home decoration and various public places. Although the surface of this light-storing luminescent film has good printability, various patterns can be printed to realize the substrate luminescence, but it takes a lot of manpower and material resources to realize its use only by printing, the scrap rate is extremely high, and it is impossible to print complex and vivid images. Vivid, high-precision patterns greatly limit the application of these products in wider fields, resulting in considerable waste. [0003] ...

AI Technical Summary

Problems solved by technology

The plastic-coated paper base of the support body is difficult to waterproof for a long time, and it is impossible to achieve real waterproofing

And no novelty, no luminous effect at night

[0004] Chinese patent CN1641103 discloses a kind of printing photo paper, this printing photo paper is based on light-storing type paper-like film, adopts various methods to coat the medium, what the medium adopts is polyethylene resin, can't reach the same level as ordinary high-grade at all. Paper-like print indicators, and no specific description of the final water resistance

[0005] Chinese patent CN2566305 discloses a kind of self-luminous photo paper. The self-luminous photo paper is based on a light-storage self-luminous film, and emphasizes that the backing layer is a white coating or a white plastic film. It is coated with an ink-absorbing layer to absorb ink The formula and water resistance of the layer are not described in detail

[0006] Chinese patent CN2731501 discloses a new type of color printing photo paper. The photo paper uses a luminous plastic film as a substrate to coat a printable coating layer. It has good water absorption, can allow saturated printing, and has a large absorption capacity, but it is not waterproof. sex not specified

[0007] At present, the printing consumables produced by all the published documents and technologies have defects such as insufficient printing color, long drying time, poor water resistance, and small application range.
