Document Type and Number:
WIPO Patent Application WO/2023/228757
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing, as a composition for coloring poly(ethylene terephthalate) (PET) or a nylon resin, a pigment composition which contains a phthalocyanine pigment and in which fading and changes in color hue after molding are unlikely to occur even in the case of injection molding at a high temperature (for example 260-300ºC). Specifically, this pigment composition for resin coloring contains a non-metal or metal phthalocyanine pigment and a transition metal salt, and the resin is poly(ethylene terephthalate) or nylon.
