Abstract

The invention relates to a shifted Al-plating paint for offset printing, a preparation method and application thereof. The paint provided by the invention comprises the following components of: by weight, 5-25 parts of cellulosic resin, 3-12 parts of polyacrylic resin, 0-5 parts of Vinyl chloride-acetate copolymer, 0-0.5 parts of an auxiliary agent and 70-86 parts of a solvent. The prepared shifted Al-plating paint can be used in the offset printing technology. In comparison with the prior art, the shifted Al-plating paint can be directly used for offset printing without the varnishing process, has excellent adhesive fastness with offset printing ink; the preparation method provided by the invention has advantages of simple technology and high production efficiency; the paint also has excellent peeling performance and good bonding fastness with an aluminium layer and a printing ink layer, and the PET basal lamina can be repeatedly used; in addition, the solvent used in the preparation of the paint contains no industrial forbidden solvent such as BTX, is safe and environmentally-friendly, and is beneficial for sustainable development.

Description

technical field [0001] The invention relates to a coating and its preparation method and application, in particular to a transfer aluminized coating suitable for offset printing and its preparation method and application. Background technique [0002] Transfer aluminized paper is recognized as an environmentally friendly packaging material in the market and is widely used in various packaging industries. It does not contain metal aluminum foil and refractory polymer materials, it is degradable and recyclable, and its cost is more economical than traditional aluminum foil composite paper and coated paper. During the production process of transfer aluminized paper, laser or holographic technology can also be used to achieve anti-counterfeiting effect and make the product more beautiful. The transfer aluminized coating is a special coating tailored for it, which has been vigorously promoted and applied in recent years. [0003] In a representative traditional lithographic pri...
