摘要 |
An ink jet recording sheet having an enhanced ink-absorbing property and bright color image-forming property and an excellent surface hardness has a specific coating layer formed on a surface of a substrate sheet, which comprises a pigment and a resinous binder composed of a cationic copolymer prepared by copolymerizing (a) 99.95 molar % or less of a principal copolymerization component comprising at least one fatty acid vinyl ester comonomer with (b) 0.05 to 0.4 molar % of a cationic copolymerization component comprising at least one cationic comonomer having an ethylenically unsaturated hydrocarbon radical and a cationic radical selected from tertiary amino radicals and quaternary ammonium radicals and, optionally, a member selected from (c) an additional copolymerization component comprising at least one polymerizable non-ionic comonomer different from the fatty acid vinyl ester and (d) a graft copolymerization component comprising polyvinyl alcohol.
