PROBLEM TO BE SOLVED: To prepare a polyurethane resin-based slash molding material having a soft feeling even at a lower temperature, not causing fogging, having long-term durability under exposure to UV and at a higher temperature, excellent in both durability such as chemical resistance and pigment dispersibility, scarcely causing color unevenness even in the case of light color and capable of imparting molded products such as automotive instrument panels by including a specific elastomer, plasticizer or the like. SOLUTION: This material includes (A) a thermoplastic polyurethane elastomer having 10,000-50,000 number average molecular weight and 120-200 deg.C thermally softening initiation temperature, (B) a plasticizer and (C) a radically polymerizable unsaturated group-including compound and, optionally, (D) an additive. It is pref. that one molecule of the component C has 3-6 radically polymerizable unsaturated groups, the weight ratio of (the component A/the component C) is [100/(0.1-10)], the prepared material is fine particles having 50-400μm average particle diameter and the content of particles having <100μm particle diameter is 50 wt.% or below. |
