HYDROPHILIC/HYDROPHOBIC PATTERN FORMING MATERIAL, HYDROPHILIC/HYDROPHOBIC PATTERN FORMING METHOD, LITHOGRAPHIC PRINTING PLATE AND METHOD FOR MANUFACTURING LITHOGRAPHIC PRINTING PLATE

摘要

PROBLEM TO BE SOLVED: To provide a hydrophilic/hydrophobic pattern forming material which can be put to a wide range of use applications and can make a fine and sharp pattern available, and a lithographic printing plate which can be directly made up based on digital data and a method for manufacturing the lithographic printing plate.;SOLUTION: The pattern forming material has a pattern forming layer, formed on a support, to the terminal of which a polymer compound having a functional group whose hydrophilic/hydrophobic natures directly change by exposure to light or change by the action of heat or acid generated by the exposure, chemically binds. The light originating from a light irradiation means is modulated using a light modulation with "n" number of sketching parts which receives/emits the light from the light irradiation means and a pattern exposure is made to the pattern forming material using the light which is passed through a microlens array having arranged microlens, with an aspherical surface, which can correct an aberration due to the distortion of an emission surface at the sketching parts. Also, the lithographic printing plate and its manufacturing method are provided.;COPYRIGHT: (C)2006,JPO&NCIPI
