Abstract
Provided are urethane resin particles for slush molding which make it possible that inconveniences based on the slip-down of a pigment, on the aggregation of particles of the pigment, and on other causes are removed although this coloring is coloring onto the resin particle surfaces. The present invention is urethane resin particles for slush mold which contain a urethane resin and an additive, wherein the particles have a shape factor SFof 101 to 200, a shape factor SFof 120 to 240, and a central particle diameter of 20 to 500 μm. It is preferred that the urethane resin has a concentration of urea groups of 0.5 to 10% by weight, a total of the concentration of urethane groups and that of the urea groups of 4 to 20% by weight, a melting point of 160 to 260° C. and a glass transition temperature of −65 to 0° C.
