Title: POSITIVE PLANOGRAPHIC PRINTING ORIGINAL PLATE AND METHOD FOR MANUFACTURING SAME, AND METHOD FOR PRODUCING PLANOGRAPHIC PRINTING PLATE
Abstract:
A positive planographic printing original plate has at least a bottom layer, an intermediate layer, and a top layer, in the stated order, on a support body having a hydrophilic surface or a hydrophilic layer. The bottom layer includes a polymer compound 1 having in a main chain at least one structure selected from the group consisting of a urethane bond, an acetal structure, and a urea bond. The intermediate layer includes a polymer compound 2 having in a side chain at least one structure selected from the group consisting of a sulfone amide group, an active imide group, and a urea bond. The top layer includes a polymer compound 3 having a phenolic hydroxy group. At least one of the three layers contains a UV-absorbing agent. The present invention also provides a method for manufacturing the positive planographic printing original plate, and a method for producing a planographic printing plate using the positive planographic printing original plate.
