PURPOSE:To make the trace of a feed roller hard to apply by enhancing the receptivity of aqueous ink and increasing film thickness, by providing an ink receiving layer and the protective layer thereof and curing the binder of the protective layer by a diffusion-resistant crosslinking agent. CONSTITUTION:A protective layer is provided on an ink receiving layer and, by curing only said protective layer, film strength can be enhanced without lowering an ink absorbing speed. As a diffusion-resistant crosslinking agent to be used, a high-molecular hardener is designated and, especially, a compound represented by formula I (wherein /A is an ethylenic unsaturated monomer copolymerizable with a monomer unit, R1 is a hydrogen atom. or a 1-6C lower alkyl group, Q is -CO2-, -CO-NR1- or a 6-10C alkylene group, L is a 3-15C divalent group containing at least one of a -CO2- bond and a -CO-NR1- bond and R2 is a vinyl group or a functional group becoming a precursor of said group and either one of -CH=CH2 and -CH2CH2X). |
