Zusammenfassung: | PURPOSE: To improve higher light resistant fastness, resistivity to a humidity and a chemical substance, solubility in a printing ink blend, a color strength, hue clarity and the like by using a specific anthraquinone dye. CONSTITUTION: An anthraquinone dye represented by a formula (wherein R is an alkyl, alkoxyalkyl, aryloxyalkyl, alkanoyloxyalkyl, alkoxycarbonyloxyalkyl or alkoxycarbonylalkyl group, which may each contain up to 20 carbon atoms and whose carbon chains may be interrupted by from one to four oxygen atoms in ether function, or is 5-8C cycloalkyl or phenyl which may each be substituted by 1-4C alkyl or 1-4C alkoxy group) is used. |
