An automobile fuel tank includes an outer wall including a main body of a multiple-layered synthetic resin, in which the outer wall includes at least an outer body layer, an outer adhesive layer, a barrier layer, an inner adhesive layer, and an inner body layer. The outer body layer and the inner body layer include a high density polyethylene (HDPE) as a main ingredient. Each of the outer adhesive layer and the inner adhesive layer includes a synthetic resin having adhesiveness against both the high density polyethylene (HDPE) and the barrier layer. The barrier layer includes a synthetic resin.

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.
