Abstract of the Disclosure Disclosed are colored, molding thermoplastic resin pellets prepared by mixing molding thermoplastic resin pellets of polyethylene, polypropylene, polystyrene, ABS resins, etc., a powdery colorant and a liquid thermoplastic adhesive of ethylene- vinyl acetate copolymer, nylon, water-soluble acrylic polymer, etc. having a water content of 5 % by weight or more followed by drying the resulting mixture whereby said powdery adhesive is made adhered onto the surfaces of said pellets. The colored pellets are prepared, using minimized equipment and running costs necessary for melting and granulating steps. When mixing the powdery colorant and the uncolored molding thermoplastic resin pellets, static electricity is not generated. The invention is free from troubles to be caused by antistatic agents and organic solvents, not needing them. 24
