<P>PROBLEM TO BE SOLVED: To provide resin particles that are free of defects associated with sliding-down or agglomeration of a pigment when pigmented on the surface of the resin particles. <P>SOLUTION: The urethane resin particles for slush molding (C) is urethane resin particles that contains a urethane resin (D) and an additive (N) and have a shape factor SF1 of 101-200, a shape factor SF2 of 120-240, and a median particle diameter of 20-500 μm. The urethane resin (D) contained in (C) has a urea group concentration of 0.5-10 wt.%, a total concentration of a urethane group and the urea group of 4-20 wt.%, a melting point of 160-260°C, and a glass transition temperature of -65 to 0°C. <P>COPYRIGHT: (C)2011,JPO&INPIT |
