Abstract
Provided is a resin molded article for an automobile interior material, the resin molded article achieving both resin strength permitting formation of a thin film, and crease resistance. This molded article is to be used in an automobile interior material, the resin molded article being obtained by slush-molding a powdered thermoplastic urethane urea resin composition (P) that satisfies (1)-(5) below, said resin composition (P) containing an additive and a thermoplastic urethane urea resin (U) obtained by reacting a high-molecular diol (a), a linear alkane diol (b), a monool (c), a diamine (d), and an organic diisocyanate (e):
- (1) (a) contains a specific polyester diol;(2) the weight of (b) is within a specific range relative to the total weight of (a)-(e);(3) the tensile strength of a film comprising (P) is 8.0 MPa or higher;(4) the storage modulus of (P) at 130° C. is 0.1-5.0 MPa;(5) the ratio of the storage modulus of (P) at 50° C. to the storage modulus at 23° C. by a specific measurement method is 50% or higher.
