COLORANT FOR THERMOPLASTIC RESIN AND USES THEREOF

摘要

A colorant for thermoplastic resins which is excellent in dispersibility, transparency, ultraviolet-shielding properties, etc.; a thermoplastic resin composition containing the colorant; and a thermoplastic resin molding having a satisfactory dispersion state, transparency, ultraviolet-shielding properties, stretchability, and surface smoothness. The colorant for thermoplastic resins comprises: surface-treated alpha-ferric oxide (A) obtained by coating non-acicular alpha-ferric oxide having an average particle diameter of 0.01 to 0.06 mum and an aspect ratio of 0.2 to 1.0 with a polyhydric alcohol and an organopolysiloxane; and a dispersant (B) comprising a metal hydroxycarboxylate (B1). It optionally further contains a methine dye (C). The thermoplastic resin composition and the molding are obtained by using the colorant for thermoplastic resins. Also provided is a molding obtained by coating the molding with a carbon film.
