Abstract
A resin laminate having a structure in which a support, an intermediate layer and an image-forming resin layer are laminated in the order mentioned, the resin laminate including (A) a cationic polymer in the image-forming resin layer, and (B) an anionic polymer in the intermediate layer in contact with image-forming resin layer, wherein the (B) anionic polymer is a modified and partially saponified polyvinyl acetate in which a carboxyl group is introduced to a polymer side chain using a hydroxyl group of a partially saponified polyvinyl acetate as an origin of introduction.
Claims10
A resin laminate having a structure in which a support, an intermediate layer and an image-forming resin layer are laminated in the order mentioned,
- the resin laminate comprising:
- (A) a cationic polymer in the image-forming resin layer;
- (B) an anionic polymer in the intermediate layer in contact with the image-forming resin layer, wherein the (B) anionic polymer is a modified and partially saponified polyvinyl acetate in which a carboxyl group is introduced to a polymer side chain using a hydroxyl group of a partially saponified polyvinyl acetate as an origin of introduction, and
- the image-forming resin layer comprises:
- the (A) cationic polymer;
- (C) a partially saponified polyvinyl acetate having 1) a side chain comprising a reactive functional group that is a non-aromatic unsaturated carbon-carbon bond, and 2) a saponification degree of 40 to 100% by mol,
- (D) a compound having a polymerizable ethylenic double bond;
- and
- (E) a photopolymerization initiator.
