Abstract
An ink jet recording medium capable of providing recorded images of excellent water resistance which is obtained by coating on a support a mixture of 100 parts by weight of a water-soluble polymer and 0.1-30 parts by weight of a crosslinking agent such as an epoxy or triazine crosslinking agent, said water-soluble polymer being obtained by copolymerizing 10-50 parts by weight of a quaternary salt monomer selected from tri-methyl-3-(acryloylamino)propylammonium chloride, trimethyl-2-(methacryloyloxy)ethylammonium chloride, etc., 1-30 parts by weight of an amino group-containing monomer selected from dimethylaminopropylacrylamide, dimethylaminoethyl methacrylate, etc. or a carboxyl group-containing monomer selected from acrylic acid, methacrylic acid, etc., and 20-80 parts by weight of a monomer selected from acrylamide, 2-hydroxyethyl (meth)acrylate, N-vinylpyrrolidone, etc.
