ABSTRACT:
Disclosed are colored, shaping thermoplastic resin pellets prepared by mixing shaping thermoplastic resin pellets of polyethylene, polypropylene, polystyrene, ABS resin, 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 equipments and running costs necessary for melting and granulating steps. When mixing the powdery colorant and the uncolored shaping 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.
