PROBLEM TO BE SOLVED: To prevent image blurring when the surface property of a recording surface is improved by suppressing an increase in viscosity and kept in a high humidity environment (including a case where it is stored in a clear file or the like immediately after recording). An ink receiving layer, together with fine particles, has an I / O value of 1.5 to 3.0, a cation equivalent of 1.5 to 5.5 meq / g, and a weight average molecular weight of 10,000. Contains an organic cationic polymer that is ~ 200,000. [Selection figure] None |
