1. A method for making a composite particulate in fused agglomerate form and which is not a collapsed microsphere having a portion comprised of at least one colorant and a portion comprised of at least one clear or translucent thermoplastic material comprising the steps of:
(a) combining one or more colorants in particulate form with polymethylmethacrylate (PMMA) in the form of solid spheres; (b) adding solvent in an amount sufficient to swell the PMMA and cause the fused agglomerates of colorant and PMMA to form; (c) removing the solvent and causing the mixture to dry, (d) subjecting the dried mixture to milling to form fused agglomerates having a particle size ranging from 1 to 100 microns. |
