Title:
PHOTOSENSITIVE PRINTING PLATE MATERIAL AND METHOD FOR MANUFACTURE OF PRINTING PLATE
Document Type and Number:
WIPO Patent Application WO/2008/056506
Kind Code:
A1
Abstract:
A method for manufacturing a printing plate, comprising the steps of: (a) subjecting a printing plate material having a substrate, a polymerized image-forming layer and an oxygen-blocking layer in this order to an image exposure procedure; and (b) developing the printing plate material by removing the unexposed region of the image-forming layer with an aqueous solution having a pH value of 3 to 9, wherein the polymerized image-forming layer contains a sensitizing dye (D) represented by the general formula (1) or (2), and the aqueous solution contains at least one member selected from a specific nonionic surfactant, a specific anionic surfactant and a compound represented by the general formula (3). The method can manufacture a printing plate material having a high sensitivity, a printing plate having high print durability or a printing plate free from the concern of scumming by a running fatigue solution.
