Abstract

This invention relates to PS sensitive coating liquid which is suitable for high speed coating and hasn't apparent disadvantage. It concludes one kind or more linear phenol formaldehyde resins, one kind or more light cure composit resins, one kind or more colorant and dissolvant. And it has the following chemical compounds. Among them, R1 represents hydroxyl, amido, ether group, sulfamide hydrophilia group. R2 and R3 represents atomic hydrogen, alkyl, hydroxy, aromatic group.R2 and R3 can be the same or different. The m represents the nature number among 1 to 20.The n represents the nature number among 1 to 10.This invention is suitable for high speed coating to the aluminum plate support. The planographic plate made by the sensitive coating liquid is apparently even, has no piebald and strip.

Description

technical field [0001] The present invention relates to the coating solution for photosensitive layer, more specifically to the photosensitive coating solution for making PS plates, that is, a pre-coating type photosensitive coating solution coated on grained aluminum plate base. Background technique [0002] PS plate, also known as pre-sensitised plate, is a lithographic printing plate made by coating a prefabricated photosensitive liquid on a hydrophilized plate base and drying it. The quality of the PS plate is not only related to its photosensitive performance, but also closely related to its apparent quality. [0003] Generally speaking, when manufacturing PS plates, the photosensitive coating solution should be applied to the aluminum plate substrate after hydrophilic treatment by various methods. The coating machines used include sheet-fed and roll-to-roll continuous production lines. The coating methods used are: spin coating, dip coating, bar coating, knife coatin...
