ABSTRACT:
Fatty acid amide coated pigments are obtained and used to formulate with thermoplastic or thermoset materials. The colors of the pigments are fully developed and extremely high pigment loadings are obtained. The coated pigments are formed by admixing the pigment with melted fatty acid amide; solidifying the material by cooling it; grinding the material; and separating out the fines. The coated pigment particles are compounded with thermoplastic or thermoset materials by low shear means, such as, injection molding. An improved form of the coated pigments can be obtained by admixing the melted fatty acid amide and the pigment; extruding the admixture to form a creamy mass; solidifying and forming the creamy mass by passing it through cold and forming rollers; grinding the resultant wafer-like material; and separating out the fines. Liquid compositions of fatty acid amide coated pigments can be obtained by admixing pigment particles and a fatty acid amide which is liquid at room temperature or by admixing a fatty acid amide, pigment particles and a non-solvent diluent which is liquid at room temperature.
