NON-AQUEOUS RESIN DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide a non-aqueous resin dispersion produced by dispersing a urethane resin in an organic solvent and having excellent monodispersity and dispersion stability (storage stability).

SOLUTION: The non-aqueous resin dispersion is produced by polyaddition reaction of a polyol (C) and a polyisocyanate (D) in the presence of a dispersion stabilizing resin (A) and a dispersion medium (B), wherein the dispersion stabilizing resin (A) is a urethane resin obtained by polyaddition reaction of a polyisocyanate (G) and a polyol (F) containing a vinyl resin (E) having two hydroxyl groups on one terminal and obtained by radical polymerization of an ethylenic unsaturated monomer (a2) in the presence of a compound (a1) having two hydroxyl groups and one mercapto group.
