Abstract
Abstract A recording medium is composed of a substrate and an ink receiving layer provided on at least one side of the substrate, wherein the ink receiving layer is composed of a composition or a cured product thereof containing at least (A) a polyvinyl acetal resin having acetal groups, acetyl groups and hydroxyl groups, (B) a monomer having an active energy ray curable ethylenic unsaturated group, and (C) a cationic resin, at a ratio (B)/(A) within the range of 1/100 to 5/1, and a ratio (C)/((A)+(B)) of 0.5/100 to 30/100.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
A method of forming an image by applying an ink to a substrate, the method comprising the steps of: forming an ink receiving layer by coating, on at least one side of the substrate, a composition comprising a polyvinyl acetal resin (A) having acetal groups, acetyl groups and hydroxyl groups; a monomer (B) having an active energy ray curable ethylenic unsaturated group; and a cationic resin (C); at a weight ratio (B)/(A) within a range of 1/100 to 5/1, and a weight ratio (C)/((A)+(B)) within a range of 0.5/100 to 30/100; applying an ink to the ink receiving layer by an ink jet method to form an image; and then applying active energy rays to the ink receiving layer to cure the ink receiving layer.
Claim 2
Independent Claim
125 words
A method of forming an image by applying an ink to a substrate, the method comprising the steps of: forming an ink receiving layer by coating, on at least one side of the substrate, a composition comprising a polyvinyl acetal resin (A) having acetal groups, acetyl groups and hydroxyl groups; a monomer (B) having an active energy ray curable ethylenic unsaturated group; and a cationic resin (C); at a weight ratio (B)/(A) within a range of 1/100 to 5/1, and a weight ratio (C)/((A)+(B)) within a range of 0.5/100 to 30/100; applying an ink to the ink receiving layer by an ink jet method to form an image; and then applying active energy rays to the ink receiving layer to cure the ink receiving layer.
