PURPOSE:The titled composition having improved releasability of burr, providing a molded article having improved packing properties, obtained by blending an unsaturated polyester resin composition containing a crosslinking agent having a polymerizable double bond with a specific amount of melamine resin. CONSTITUTION:A composition containing an unsaturated polyester obtained by reacting an alpha,beta-unsaturated dibasic acid and a saturated dibasic acid as acid with a glycol and 10-50wt% crosslinking agent (e.g., styrene or triallyl cyanurate) having a polymerizable double bond (a ratio of the crosslinking agent is 3-50wt%) is blended with 2-40wt% melamine resin.
