FIELD: chemistry.
SUBSTANCE: cationic resin for pigment dispersion, such as polyepoxide amino resin containing an acid-neutralised amine group. Resin is obtained from a monoepoxide amine compound formed during reaction of monoepoxide and amine, having three or more active hydrogen atoms, and a quaternary ammonium salt group in the middle of its chain.
EFFECT: invention enables to obtain a good appearance of the coating, good pigment dispersion and stability during prolonged storage.
