Document Type and Number:
WIPO Patent Application WO/2017/168831
Kind Code:
A1
Abstract:
A lithographic printing original plate for on-press development, which comprises, on an aluminum supporting body, an intermediate layer containing a compound that has a supporting body-adsorbing group and a hydrophilic group, and an image recording layer containing an infrared absorbent, a polymerization initiator, a polymerizable compound and polymer particles that are formed of a styrene copolymer. The aluminum supporting body is an aluminum plate that has an anodic oxide coating film on a surface which is in contact with the intermediate layer; the anodic oxide coating film has micropores that extend in the depth direction from the surface which is in contact with the intermediate layer; and the average pore diameter of the micropores in the anodic oxide coating film surface is 20-40 nm. A method for producing a lithographic printing plate, which uses the above-described lithographic printing original plate for on-press development; and a lithographic printing method.
