MASTER BATCH FOR COLORING RESIN AND COLORED RESIN MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a master batch for coloring a resin capable of producing a colored resin molded product which is reduced in the dissipation amount of VOC and suppressed in odor and has a stable and desirable ivory hue at a low cost.SOLUTION: There is provided a master batch for coloring a resin used for producing a colored resin molded product which is reduced in the dissipation amount of a volatile organic compound. A coloring agent includes titanium oxide, a yellow pigment, carbon black and the like. The titanium oxide is first surface treated titanium oxide which is surface treated with alumina but is not surface treated with siloxane or second surface treated titanium oxide which is surface treated with at least siloxane. The yellow pigment is at least any one of yellow iron oxide and chromium titanium yellow (provided that if titanium oxide is the second surface treated titanium oxide, the yellow pigment includes chromium titanium yellow).
