To provide irregular finish coating materials capable of forming patterned coated films which meet both processability at low temperatures and blocking resistance at high temperature.

This coating material composition comprises 100 pts.wt. sum of (A) 60-95 pts.wt. hydroxyl group-containing polyester resin and (B) 5-40 pts.wt. amino resin, (C) 2-40 pts.wt. organic polymeric fine particles having an average particle diameter of 0.2-80 μm, and (D) 1-15 wt.% cellulose ester derivative to be obtained by the ring-opening polymerization of a cyclic ester onto a cellulose ester having hydroxyl groups.
