PURPOSE: To enhance color forming properties, water resistance and light fastness by using a polymer obtained by polymerizing acrylic ester represented by a specific formula and a copolymerizable nonionic vinyl monomer other than (meth)acrylic ester in a specific ratio as an effective component. CONSTITUTION: In an ink jet recording medium forming a recording image having high resolving power and excellent in color forming properties, water resistance and light fastness using aq. ink, an additive for ink jet recording containing a polymer obtained by polymerizing 50-100mol% of (meth)acrylic ester represented by formula (R is hydrogen or a methyl group and R1 is a 1-2C alkyl group, that is, a methyl group or an ethyl group) and 9-50mol% of a copolymerizable nonionic vinyl monomer other than (meth)acrylic ester as an effective component is internally added to a support or applied to the support. In this case, a cationic dispersion is pref. prepared in order to uniformly fix ink. |
