<P>PROBLEM TO BE SOLVED: To provide a print plate material capable of recording an image by infrared laser exposure with an improvement in a development property on a printer, scanning and visible image property of exposure. <P>SOLUTION: The print plate material has an image forming layer containing a thermoplastic particulate and an optothermal converting dye which can be developed on a printer on an aluminum substrate to which an electrolysis roughening treatment and anodizing treatment are applied. The image forming layer has the function that hue is changed by infrared laser exposure and etching treatment by an alkali aqueous solution is applied to the aluminum substrate after carrying out the electrolysis surface roughening treatment. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
