A coloring paint composition comprising: (a) 5-60 wt.% (based on the total solid content of the composition; the same applies hereinbelow) of a polymer having carboxyl and carboxylic ester groups, (b) 5-60 wt.% of a polymer having hydroxy and epoxy groups, (c) 0.05-20 wt.% of a pigment dispersant, and (d) 0.1-50 wt.% of a pigment, and satisfying the relationship of AR > 0.5 BP or BR > 0.5 AP, and AR + AP > BR, wherein AR and BR refer to the total acid content and total base content, respectively, ascribed to the pigment dispersant, while AP and BP refer to the total acid content and total base content, respectively, ascribed to the pigment. Thus provided is a solid color paint composition that can meet the requirements of scuff resistance, acid resistance, shelf stability, and excellent appearance. |
