| titleOfInvention | Granular colorant for synthetic resin and process for producing the same |
| abstract | A granular colorant for a synthetic resin is provided, having the advantages that there is no contamination to the hands of an operator, molding apparatuses and the working environment, that the particle size is uniform, the weighing accuracy in using an automatic batching feeder is high, the mixing ratio of the colorant and a resin does not change, the dispersibility to a molding resin is good, the production is simple, and the production cost is low. The granular colorant has a particle size of 7 to 100 meshes, and comprises thermoplastic resin powder particles having a particle size of 5 to 100 meshes as a nucleus, a colorant composition comprising a coloring component which comprises an organic or inorganic dye or pigment, and optionally, a binder, wherein the colorant composition is fixed onto the surface of the thermoplastic resin powder particles. The colorant can be produced by mixing the thermoplastic resin powder as the nucleus, the coloring component and the dispersant with a mixing machine, and fixing the coloring composition onto the surface of the nucleus by the dispersant melted by friction heat generated in mixing, or mixing the thermoplastic resin powder, the coloring component, and the dispersant, adding the binder to the resulting mixture at a time when the friction heat generated by mixing does not sufficiently rise, and further mixing the resulting mixture. Colored synthetic resin molded products can be obtained by mixing the granular colorant with a thermoplastic molding resin, and molding the resulting mixture. |
