ABSTRACT:
A production process of colored resin powder, comprising a coloring step of mixing 0.5 to 40% by mass of a colorant (b1) with 99.5 to 60% by mass of a non-phthalic acid plasticizer (b2) to prepare a colored paste (B) and adding and mixing the colored paste (B) into a powdery thermoplastic polyurethane-urea resin (A), wherein the amounts of the colorant (b1) and the plasticizer (b2) contained in the colored paste (B) added to the powdery thermoplastic polyurethane-urea resin (A) are 0.1 to 5 parts by mass and 1 to 20 parts by mass, respectively, per 100 parts by mass of the thermoplastic polyurethane-urea resin. According to the production process, there can be provided colored resin powder, which is free from color mottling (color unevenness) on its surface and does not cause smearing of a molded product due to separation and falling of the colorant upon a molding process or the like.
