  • Synthetic resin composition and interior material coated with the same
    Patent number: 5622778
    Abstract: 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.
