Abstract

The invention relates to a laser mould pressing alcohol soluble aluminizing transfer paint and preparation method thereof and application thereof in production of holographic aluminizing transfer paper and common aluminizing transfer paper. The paint comprises the following raw materials (by weight percent): 0-17% of cellulose ester, 0-25% of acrylic resin, 60-73% of main solvent, 3-10% of water and 0-2% of assistant; wherein the cellulose ester and the acrylic resin are film-forming resin, at least one of the two is included, the hydroxyl content of the cellulose ester is 3-8%, Tg value of the cellulose ester is 130-160 DEG C, the acid value of the acrylic resin is 40-60mg KOH / g, and the Tg value of the acrylic resin is 60-160 DEG C; and the content of alcohol solvent in main solvent is at least 70wt%. The main solvent of the paint of the invention is alcohol solvent, contains no solvent harmful to human body and contains appropriate water as assistant, thus eliminating volatilization of harmful solvent in coating process; and the paint dried after coating has favourable water resistance and solvent resistance, and indexes thereof including the laser mould pressing property, high temperature resistance and after-tack in high temperature high humidity environment can meet usage requirement.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly laser moldable alcohol-soluble aluminized transfer coating and a preparation method and application thereof. technical background [0002] As a new type of packaging material, holographic aluminized transfer paper has been widely used in the packaging of social consumer products such as tobacco, wine bags, tea and cosmetics with its absolute advantages in environmental protection and anti-counterfeiting, and has a broad market prospect. [0003] The performance of the laser aluminized transfer coating is one of the key factors to realize the manufacture of this holographic aluminized transfer paper. Since the holographic effect is achieved by laser molding and aluminizing on the dried coating, the coating performance directly affects the final packaging. The material can be laser molded, high temperature and high humidity resistance, and post-processing ...
