Problems solved by technology

[0003] At present, almost all the coatings used for transfer coating are thermoplastic resin solvent systems. The molding process of this coating adopts hot-pressed thermoplastic resin coating, and the coating information layer made will decrease with the time of hot pressing. In severe cases there will be missing information
This situation can be avoided by using the UV coating light-solid molding process. The UV coating is liquid before the light-curing molding, and the template information will be completely copied during the molding. The UV coating is separated from the template during the light-curing molding. There will be a situation where the information of the traditional thermoplastic coating is missing for a long time, but the UV coating and the polyester film used as the base material cannot be peeled off well, and it is easy to lose some light and whiteness during transfer

Abstract

The invention discloses a UV-laser transfer paint composition and a use thereof. The composition comprises a component A and a component B, wherein the component A comprises the following ingredients in parts by weight: 1-80 parts of light-cured resin, 1-100 parts of photo-polymerizable monomers, 1-20 parts of a photoinitiator and 0-10 parts of auxiliaries; the component B comprises the following ingredients in parts by weight: 0-16 parts of cellulose resin, 0-6 parts of chloride acetate resin, 4-15 parts of acrylic resin, 0-3 parts of auxiliaries and 60-90 parts of a solvent. The use of the composition comprises the following steps: coating a PET base material with the component B and drying; then, coating the component B coating with the component A on; carrying out mold pressing on the component A coating and performing a UV-light curing process to produce holographic effects. The coating made of the UV-laser coating has the advantages of scratch resistance, good fullness, no deformation, good weather resistance and the like, and also has the advantages of excellent stripping quality, complete holographic aluminum-coated layer transfer, energy conservation and quickness, improved production efficiency and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a UV-laser transfer coating composition and its application. Background technique [0002] In recent years, with the requirements of environmental protection and resource conservation, most of the paper packaging used for tobacco, alcohol, food, daily necessities, etc. is made by the transfer method, which is to transfer the aluminum coating with laser effect to the The surface of the paper base forms an aluminized paper with a metallic luster. [0003] At present, almost all the coatings used for transfer coating are thermoplastic resin solvent systems. The molding process of this coating adopts hot-pressed thermoplastic resin coating, and the coating information layer made will decrease with the time of hot pressing. In severe cases There will be missing information. This situation can be avoided by using the UV coating light-solid molding process. The UV coating is liquid before the ...
