Abstract
Abstract The present invention relates to the development of a coloring matter which has a moderately bluish magenta color and an excellent lightfastness and can provide a wide range of color tones in the visible range when used together with yellow and cyan inks. A water-base ink composition or the like is prepared by using a sulfonic acid derivative of an anthrapyridone compound represented by general formula (I) as a magenta dye, wherein R 1 ' represents alkoxycarbonyl, carbonyl or benzoyl; R 2 represents hydrogen or alkyl; and R 3 and R 4 represent each independently hydrogen, halogeno, alkyl or alkoxy. ##STR1##
