Problems solved by technology

Now, as people's requirements for packaging are getting higher and higher, laser patterns with deep grooves (depth of micron level) have appeared, and the existing solvent-based composite laser coatings can no longer meet production requirements.
Therefore, PE mate...

Abstract

The invention discloses a UV (Ultraviolet)-compound laser coating composition which is a 100% UV containing coating. The composition comprises the following components in parts by weight: 10-60 parts of a light-cured resin, 35-75 parts of a photopolymerization monomer, 2-8 parts of a photoinitiator and 0-3 parts of an assistant. According to the UV-compound laser coating composition disclosed by the invention, a holographic laser effect is obtained by using mould pressing and a UV illuminating and curing process. As the mould pressing and the UV illuminating and curing process are adopted at the same time, the UV-compound laser coating composition not only can be used for obtaining the laser effect of a common shallow groove, but also can be used for making a laser pattern of a deeper groove. Compared with the prior art, the composition disclosed by the invention further has the advantages that by adopting the 100% UV containing formula which contains fewer solvents or no solvents, during use, less solvents volatilize, so that air pollution is reduced; by adopting UV curing, the energy resources are saved and the speed is fast, and the production efficiency is improved; the temperature is low during UV curing, and the influence on the base material in temperature distortion is reduced.

Description

technical field [0001] The invention relates to the field of UV photocuring coatings, in particular to a UV-composite laser coating composition. Background technique [0002] PET laser aluminized film has always occupied a place in the packaging field due to its unique functionality, strong metallic appearance, and dazzling laser effects. It is widely used in new packaging materials for tobacco, alcohol, food, cosmetics, tea, gifts, etc. . The basic performance of the composite laser aluminized coating is its adhesion and molding effect. The adhesion includes two parts: the adhesion of the coating to the base film (usually PET film), and the adhesion of the aluminized layer to the coating. The embossing effect refers to the holographic laser effect on the coating through the embossing process. [0003] The existing composite laser aluminized coating is a solvent-based system, which uses a large amount of organic solvents. On the one hand, the high content of volatile organ...
