Title
(EN) Planographic printing plate precursor
(ZH) 平版印刷版原版
Abstract
(EN)
A planographic printing plate precursor according to the invention includes: a support; and a recording layer disposed on the support and containing an alkali-soluble polymer compound and an infrared absorber, wherein a contact angle at a surface of the planographic printing plate precursor is 70 DEG or less in a case of oil in water and 140 DEG or more in a case of water in oil. Examples of a method for achieving such surface physical properties include inclusion, in a recording layer, of a polymer having a lipophilic functional group on a side chain thereof. According to the invention, a planographic printing plate precursor for direct print making can be obtained, which precursor improves the image forming property of the recording layer using an alkali-soluble polymer compound, is excellent in the lipophilicity of an image portion and the removing property of a non-image portion, and produces printed matters of high quality with excellent reproducibility even in the image formation with an FM screen or high number of output lines.
