Changing the heat sensitive material for lithography formation, production manner of the edition material and the edition material,

摘要

PROBLEM TO BE SOLVED: To improve sensitivity to heat in plate-making in a heat-sensitive type form plate material capable of obtaining a lithography which is excellent in plate wear without requiring a developing process. ;SOLUTION: A heat-sensitive layer 2 wherein a fine particle 4 is uniformly distributed in polyacrylic acid 3 is formed on a substrate 1. The fine particle 4 comprises a micro-capsule 41 and a lipophyllic component 42 contained in the micro-capsule 41. Polyvinyl alcohol-polyvinyl acetate copolymer is added to a part 21 to an at least form plate surface side of the heat-sensitive layer 2.;COPYRIGHT: (C)2001,JPO
