Abstract (en)

[origin: EP2644403A1] Provided is a method for producing an inkjet recording material, the method comprising the steps of mixing an aqueous solution of a saponified vinyl acetate-diacetone acrylamide copolymer with a crosslinking agent to give a liquid mixture (a) ; adding a water-soluble basic compound to the liquid mixture (a) after a lapse of at least 30 minutes to give another liquid mixture (b); and mixing the obtained liquid mixture (b) with porous inorganic fine particles to give an ink receiving layer coating liquid and applying the coating liquid to a support, the inkjet recording material being characterized in that the ink receiving layer comprises the porous inorganic fine particles, the saponified vinyl acetate-diacetone acrylamide copolymer, and the crosslinking agent.
