PURPOSE:To obtain ink jet recording paper which forms a high-resolution and highly waterproof recorded image by containing polyvinyl alcohol resin (abbreviated as PVA) having the cationic group in paper base material and/or a coated layer. CONSTITUTION:Ink jet recording paper containing PVA based on the cationic group in paper and/or a coated layer allows a specially high-resolution and highly waterproof recorded image to be formed. PVA having the cationic group is a saponified product of a copolymer composed of vinyl acetate and a monomer having the cationic roup shown by a general formula. The dosage of PVA resin containing the cationic roup to be added to ink jet recording paper is normally 0.01-10g/m<2>. PVA resin containing the cationic group is having various fillers such as talc or kaolin, or paper containing white pigment as a coated layer. This enables the formation of a high-resolution and highly waterproof recorded image. |
