LOW-STAINING COATING COMPOSITION, AND LOW-STAINING COATING FILM PRODUCED FROM THE SAME

摘要

A low-staining coating composition comprising: a coating composition which comprises (A) a coating film-forming resin, (B) a hydrophilizing agent having a hydrolyzable group and (C) an organic solvent capable of dissolving or dispersing therein the resin (A) and the hydrophilizing agent (B); and (D) a hydrolysis-promoting catalyst dispersion, blended into the coating composition, which comprises an organic transition metal compound (D-1) capable of promoting the hydrolysis by the hydrophilizing agent (B) and an organic solvent (D-2) having a carbonyl group as well as a carbonyl group and/or a hydroxyl group and having a catalyst blocking property against the organic transition metal compound (D-1). By using this coating composition, the surface hydrophilization of the coating film by the hydrophilizing agent can be expressed with high efficiency and with effective timing and a coating film having low staining property can be formed early in the course of the film formation process.
