Patent ID: 6908648

Claim:
An ink-jet recording sheet comprising a support supporting the following layers: (a) porous layer; and (b) a surface porous layer comprising an organic particle; said organic particle comprising a copolymer having a recurring unit represented by Formula (1) in an amount of not less than 5 weight % based on the total weight of the copolymer, wherein represents —O— or —N(R 2 )—; R 1 represents a hydrogen atom or a methyl group; R 2 represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms; J represents an alkylene group having 2 to 18 carbon atoms which may be substituted with an ether group or a thioether group when X is —O—, or J represents a single bond or an alkylene group having 2 to 8 carbon atoms which may be substituted with an ether group or a thioether group when X is —N(R 2 )—; and Y represents a hydrogen atom, a hydroxyl group, an amino group or an alkoxy group; wherein the surface porous layer is located on the surface side of the sheet as compared with the porous layer, wherein the organic particle has an average particle size of not more than 100 nm and a glass transition temperature of not less than 70° C., and wherein the porous layer or the surface porous layer comprises a compound having a polyvalent metal element.
