    摘要： A method for preparing encapsulated red phosphorus is disclosed. The method entails obtaining a material system that contains dispersed particulate red phosphorus having a mean particle size of 0.1 to 100 nullm in an aqueous phase that comprise urea, formaldehyde and a water-soluble silicon dioxide precursor, adding to the material system a sufficient amount of acid to lower the pH to 0 to 5 and maintaining the resulting acidic system at a temperature of 80 to 120null C. for a period longer than one hour. The encapsulated red phosphorus of the invention is suitable for using as a flame retarding agent for plastics molding compositions.

    摘要： A powder-based coating composition for coating a substrate, having a first color effect, with a film layer is disclosed. Application of the film layer to the substrate produces a second color effect different from the first color effect. The composition includes a powder-based binder and a color effect-providing pigment. The powder-based binder is the reaction product of a resin, having a functional group, and a cross-linking agent reactive with the functional group. The color effect-providing pigment includes a pigment substrate and an inorganic coating. The pigment substrate has first and second substantially parallel and planar surfaces, and the inorganic coating is disposed on the first and second surfaces. The inorganic coating has an index of refraction of 1.8 or less. To produce the second color effect, the inorganic coating and the pigment substrate of the color effect-providing pigment interact with the first color effect of the substrate upon application of the film layer to the substrate.
