To obtain the subject resin composition effective in coloring a textile product requiring a high level of pigment dispersion or a polyolefin-based resin composition containing an inorganic filler or a fiber reinforcing material at high contents by combining a specific component with a pigment.
This resin composition for coloring comprises (A) 5-80wt.% of a resin and/or a wax prepared by reacting (a) a thermoplastic resin and/or a wax having carboxyl groups or acid anhydride groups (e.g. preferably a copolymer containing acrylic acid) with (b) a polyalkylene oxide compound having a functional group reactive with the carboxyl groups or acid anhydride groups (e.g. preferably a compound having 100-10,000 molecular weight), (B) 0.01-90wt.% of a pigment (e.g. an azo-based organic pigment) and preferably further (C) 5-94wt.% of a thermoplastic resin having 0.1-400 melt flow rate (e.g. a crystalline or an amorphous polypropylene).
