Problems solved by technology

Taking advantage of the good adhesion of some types of UV-curable coatings to plastic substrates and poor adhesion to metals (such as nickel plates), UV-curable coatings have been applied to holographic pattern transfer technology in recent years, as proposed in Chinese patent No. 97114329: "A laser holographic

Abstract

The invention relates to a UV coating for UV make-up copying of holographic patterns and a use method of the UV coating. The UV coating comprises a B-type coating and an A-type coating. The B-type coating comprises low-viscosity polyester acrylate, silicone-modified polyester acrylate, a polyurethane acrylate, monomers, auxiliaries and photoinitiators. The A-type coating comprises a polyurethane acrylate, the low-viscosity polyester acrylate, the monomers, auxiliaries and the photoinitiators. The B-type coating is added drop by drop between a holographic nickel plate and a transparent PET substrate, then a transparent holographic film plate is obtained by processing; then the A-type coating is added drop by drop between the transparent holographic film plate and the transparent PET substrate, a transparent holographic plate is copied out by processing; a transparent holographic large plate is obtained through repeated operation; a broad-width holographic dedicated mother plate is obtained through metallization processing on a coating curing layer of the transparent holographic large plate. The UV coating has a good adhesion on the plastic substrate, a bad adhesion on the holographic nickel plate, scratch resistance, and a good solvent resistance, and is benefit for completely copying and transferring of holographic patterns on the nickel plates.

Description

technical field [0001] The invention relates to the field of holographic anti-counterfeiting printing, in particular to a UV curable coating for imposing and replicating holographic information patterns and a method for using the coating. Background technique [0002] One of the most important processes of molded holographic technology is to make a holographic molded master. In the mass production process of molded holographic products, the holographic molded master is required to have a larger size, that is, a wide holographic molded master. Under the prior art, the manufacturing method of the wide-width holographic molded template is to directly emboss the holographic pattern on the small-sized holographic molded template onto the plastic sheet through an imposition machine, and then electroform the plastic sheet after metallization to obtain The wide-width holographic molded master plate is recast to obtain a wide-width holographic molded template. Because small-sized sp...
