1. A method for producing a printed matter, comprising:
providing an ink comprising:
a binder (A) of a core-shell polymer having a core portion comprising an acrylic polymer of a vinyl monomer component containing diacetone acrylamide having a carbonyl group, and a shell portion comprising an arbitrary acrylic polymer;
adipic dihydrazide as a compound (B);
water;
a surfactant selected from the group consisting of anionic surfactant, nonionic surfactant, cationic surfactant, and amphoteric surfactant; and
a solvent (C1) in which the binder (A) and the compound (B) are dissolved or dispersed, the solvent (C1) selected from the group consisting of 1,2-propanediol, 1,4-butanediol, 1,3-butanediol, 1,2-butanediol, 3-methyl-1,5-pentanediol, 2-methyl-1,3-propanediol, 3-methyl-1,3-butanediol, and 3-methyl-1,4-butanediol;
bringing the ink in contact with a surface of a recording medium; and
drying the ink while maintaining the surface temperature of the recording medium in a range of 5 to 60° C. such that the carbonyl group of the diacetone acrylamide in the core portion reacts with the adipic dihydrazide when the solvent (C1) volatilizes, thereby forming a structure represented by the following chemical formula (1):
