ENVIRONMENT FRIENDLY WATERLESS OFFSET PLATE

摘要

Disclosed is an environment friendly waterless offset plate. The waterless offset plate is formed by: coating a base coating on a surface of a metal plate substrate not subject to electrolytic graining and/or anodic oxidation treatment but subject to oil-removal solution immersion, coating a diazonaphthoquinone light-sensitive adhesive layer on a surface of the base coating, coating an ink-repulsive layer on a surface of the diazonaphthoquinone light-sensitive adhesive layer, and further covering a polymer protective film on a surface of the ink-repulsive layer. The waterless offset plate has a good printability, and has a pressrun up to 10 to 30 thousand copies.

1. An environment friendly waterless offset plate, obtained by coating a base coat layer on the surface of a metal plate substrate not subjected to electrolytic graining and/or anodic oxidation treatment but subjected to oil-removal solution immersion instead, coating a diazonaphthoquinone photosensitive adhesive layer on the surface of the base coat layer, and coating an ink-repulsive layer on the surface of the diazonaphthoquinone photosensitive adhesive layer;
the base coat layer is a coating formed by spreading a base coat liquid constituted by 0˜50 wt % polymer, 0.01˜20 wt % metal adhesion promoter, 0.01˜20 wt % anti-halation nanometer particles, and organic solvent that accounts for the remaining percentage on the surface of the metal plate substrate and the drying the coating; the ink-repulsive layer is a coating formed by spreading an ink-repulsive liquid constituted by 5˜30 wt % silicone rubber or fluoro resin, 0.01˜2 wt % curing agent, and organic solvent that accounts for the remaining percentage on the surface of the diazonaphthoquinone photosensitive adhesive layer and then drying the coating.
