Abstract
Abstract Pattern coloring material for synthetic resins, comprising particulate matter of a cross-linked olefin polymer containing pigment, which is useful as a material for producing synthetic resin molded products with colored patterns. The material is produced by kneading crosslinkable olefin polymer with pigment, granulating the kneaded mixture and subjecting the particulate matter thereby obtained to a cross-linking treatment.
