  • Patent number: 6837925
    Abstract: A coloring pearlescent flake pigment capable of providing pearl-like luster caused by interference color and a vivid color caused by a tar color is provided as a new material which contributes to the diversification of cosmetics and paints thanks to its powdery smoothness and the visual effect as well as covering protection effect in an application layer. The coloring pearlescent flake pigment having a double coating layer which is formed on inorganic flake-like particles and which is composed of a high-refraction-index metal oxide (e.g.

  • Patent number: 4340697
    Abstract: The present invention relates to a heat resistant molding resin composition comprising 60-99.9% by weight of an aromatic polyamideimide resin, and 40-0.1% by weight of a thermoplastic resin which comprises at least one member selected from the group consisting of a polyphenylene sulfide resin, a polyamide resin, a polysulfone resin, an aromatic polyester resin, a polyphenylene-ether resin and a phenoxy resin. The thermoplastic resin must have a melt viscosity at 350.degree. C. of not more than 1.times.10.sup.5 poise and a decomposition temperature of not lower than 350.degree. C. The aromatic polyamideimide resin is improved in melt viscosity characteristics by being blended with the thermoplastic resin. Therefore, a resin composition is obtained which is excellent in moldability characteristics. This composition may optionally comprise various kinds of fillers.
