An trim material for the interior of an automobile obtained by successive injection molding. The trim comprises a surface layer and a base layer. The surface layer is formed from a composition comprising: (A) a partially cross-linked thermoplastic elastomer comprising a polypropylene resin and an &agr;-olefin copolymer rubber, and (B) a polybutylene-1 resin. The base layer is formed of a polypropylene resin or a blend of polypropylene resin and an organic filler. The interior trim material is lightweight, is easily recycled, and generates no hazardous gas when incinerated.

Interior trim for automobile

A synthetic resin composition comprises an aqueous medium, a surfactant, and a resin and filler dispersed in the aqueous medium by the surfactant. The surfactant comprises a first high molecular weight compound having a weight-average molecular weight of at least 10000 and a second high molecular weight compound having a weight-average molecular weight of not less than 150 and less than 10000. In the synthetic resin composition, a solid material is well dispersed and the viscosity doesn't remarkably increase even if a solid content is increased. So, the increased amount of a non-volatile matter may be used and the storage stability improves. Further, flame retardation, deodorization, heat resistance and light fastness also improve. In addition, an interior material which is a fabric coated with the synthetic resin composition is provided. In the interior material, the texture, flame retardation, deodorization and light fastness improve without the deterioration of workability.
