分散させたマスターバッチ等が使用されている。Traditionally, dyes and pigments have been dispersed with dispersants such as low molecular weight polyethylene and fatty acid metal soaps as colorants for polyolefin resins such as polyethylene and polypropylene, and other synthetic resins, or dyes and pigments using these dispersants have been used. A masterbatch or the like is used, in which the compound is dispersed at a high concentration in polyethylene or other carrier resin.

が避けられない。However, with conventional powder colorants and masterbatches, the concentration of dyes and pigments cannot be made very high, and in recent years, the coloring of polyolefin-based and other synthetic resins has tended toward high dilution ratios and high-speed coloring. It is becoming increasingly difficult to provide sufficient support with colorants and masterbatches, especially in the case of thin-walled, large-sized injection molded products. Therefore, the problem of poor appearance such as color unevenness of the molded product is unavoidable.

十分に解決できることを知見して本発明を完成した。As a result of intensive research in order to solve the above-mentioned drawbacks of the prior art, the present inventors have discovered that by selecting a specific material as a dispersant for a powder colorant or a masterbatch, the dye and pigment of a powder colorant or a masterbatch can be improved. The present invention was completed based on the finding that even if the content is high, the dye and pigment in the powdered colorant or masterbatch can be dispersed at high speed in the resin to be colored, and the above-mentioned drawbacks of the conventional technology can be sufficiently solved. .
