PROBLEM TO BE SOLVED: To provide a method for producing a resin dispersion liquid and a colorant, which have less dispersion and excellent dispersion stability, and an electrophotographic developer, a paint, a printing ink and an ink jet ink using the same. Offer. SOLUTION: In the presence of a non-aqueous solvent, α, β unsaturated aliphatic carboxylic acid and α-olefin copolymer, α, β unsaturated aliphatic carboxylic acid ester and α-olefin copolymer, Alternatively, a copolymer resin selected from an α, β unsaturated aliphatic carboxylic acid, an α, β unsaturated aliphatic carboxylic ester and an α-olefin copolymer is heated to 60 to 150 ° C. and crosslinked by a crosslinking agent. A method for producing a resin dispersion to obtain a resin dispersion. |
