Summary:PURPOSE:To provide the titled particulate resin which is free from bleeding or blotting of color, hardly causes thickening, has excellent flow characteristics and workability and is useful as a color aggregate which enables easy patterning, by providing a synthetic resin film on the surface of a particulate resin colored by a pigment, a dye, an ink, etc. CONSTITUTION:A particulate resin having a particle size of 100-1,000mu such as PVC, a vinyl chloride/ethylene/vinyl acetate copolymer, etc. is introduced into a mixer and the surface of said resin is wetted with a plasticizer or an org. solvent. A pigment, a dye or an ink is then added thereto and the mixture is mixed at 15-30 deg.C for 1-15min to obtain a colored particulate resin. A synthetic resin emulsion such as an acrylic resin emulsion, etc. is added to the particulate resin and the mixture is mixed at 70-160 deg.C for 2-20min to obtain a colored particulate resin coated with a synthetic resin film.
