<P>PROBLEM TO BE SOLVED: To provide a disperse dye mixture having excellent color reproducibility in a wide color reproduction range, particularly in a hue range of blue-cyan-green-yellow when used for text printing. <P>SOLUTION: The dye mixture contains at least one pyrroline dye (component (A)) selected from dyes represented by general formula (1) and at least one anthraquinone dye (component (B)) selected from dyes represented by general formula (2). In general formula (1), R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>each independently denote unsubstituted 1-6C alkyl, allyl, 1-6C-akoxy-1-4C-alkyl, phenoxy-1-3C-alkyl, optionally substituted phenyl, aryl-1-3C-alkyl, 1-6C-alkoxycarbonyl-1-3C-alkyl or phenoxyethoxycarbonyl-2-3C-alkyl, and R<SP POS="POST">3</SP>denotes optionally substituted phenyl-1-3C-alkyl, 1-6C-alkoxycarbonyl-1-3C-alkyl, phenoxyethoxycarbonyl-2-3C-alkyl or cyano-1-2C-alkyl. In general formula (2), R<SP POS="POST">4</SP>is (CH<SB POS="POST">2</SB>)<SB POS="POST">n</SB>OR<SP POS="POST">5</SP>, R<SP POS="POST">5</SP>denotes unsubstituted 1-5C alkyl or 1-6C-alkoxy-1-3C-alkyl, and n denotes 1-6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
