A magenta toner for developing electrostatic images which comprises a resin and at least one kind of the dis-azo dye represented by the following formula [I]: <IMAGE> [I] wherein X represents methyl group, ethyl group or alkoxy group having 1 to 4 carbon atoms; Y represents hydrogen atom or methyl group; R1 and R2 independently represent hydrogen atom, alkyl group, alkoxy group or halogen atom; Q and Q' represent naphthol AS residue. This magenta toner is good in transparency, color fastness to light, heat resistance, bleeding resistance and spectral property and offers good color reproduction as a toner for full-color images. A colored resin, a colored molded resin member and a color filter dyed with at least one kind of the dis-azo dye represented by Formula [I], These are good in color fastness to light, bleeding resistance, heat resistance, transparency, spectral property and durability.
