FIELD: chemistry.
SUBSTANCE: invention relates to a paste resin which can be used to prepare pigment paste compositions for tinting of coloured paints. Resin A for pigment paste is a mixture of at least two acrylic copolymer resins A1 and A2. Copolymer resin A1 comprises at least one basic acrylic comonomer and further vinylic monomer A13 being a hydrophilic vinyl monomer having a moiety, derived from polyethylene glycol or a mixed ether of ethylene and propylene glycol. Acrylic copolymer resin A2 comprises at least one acidic acrylic comonomer.
EFFECT: resin is provided that is compatible with most types of pigments, as well as most resin binders.
