Patent ID: 6838135

Claim:
An ink-jet paper having a support provided thereon an ink receiving layer and a porous layer provided on the ink receiving layer, wherein the porous layer contains organic particles with an average particle diameter of not more than 60 nm, the organic particles contain a polymer having a glass transition point Tg of not less than 70° C. and comprising a repeating unit represented by Formula 1 in an amount of not less than 5% by weight, in the formula, X is —O— or —N(R 2 )—, R 1 is a hydrogen atom or a methyl group, R 2 is an alkyl group having 1-8 carbon atoms, and when X is —O—, J is an alkylene group having 2-18 carbon atoms which may have ether or thioether structure, and Y is a hydroxy, alkoxy, or carbamoyl group, and when X is —N(R 2 )—, J is a simple bond, or an alkylene group having 2-18 carbon atoms which may have ether or thioether structure, and Y is a hydrogen atom, a hydroxy, amino, alkoxy, or carbamoyl group.
