PURPOSE:The titled composition, containing a specific polyester resin which is a dehydration condensate of a polyhydric alcohol containing a cyclic aliphatic dihydric alcohol with a polyfunctional carboxylic acid and a reactive group- containing resin in a specific proportion and having improved chipping resistance. CONSTITUTION:A composition containing (A) a polyester resin which is a dehydration condensate of (i) a polyhydric alcohol containing 20-85wt% cyclic aliphatic dihydric alcohol, e.g. cyclohexane-1,4-dimethylol, etc., with (ii) a polyfunctional carboxylic acid and has 2,000-10,000 number-average molecular weight and average 2.1-2.8 hydroxyl groups in one molecule and (B) a resin containing reactive groups reactive with hydroxyl groups, e.g. amino resin, etc., at 90:10-60:40 weight ratio.
