Abstract
The present invention relates to a novel anthrapyridone compound represented by Formula (1) as described below or the salt thereof which has hue and vividness suitable for ink-jet printing and give a print excellent in fastness to light and water, a water-based magenta ink composition containing any of the compounds or salt thereof, an ink-jet printing method using the ink composition and a new intermediate. wherein, R1 is hydrogen atom, an alkyl group etc; R2 is hydrogen atom, methyl etc; X and Y represent independently chlorine atom, hydroxy, etc.
Claims20
A novel anthrapyridone compound represented by Formula (1) as described below or the salt thereof
- wherein, R1 is hydrogen, an alkyl group, a hydroxy lower alkyl group, cyclohexyl, a mono- or di-alkylaminoalkyl group, or a cyano lower alkyl group;
- R2 is hydrogen, methyl, ethyl, phenoxy which may be substituted, sulfo or carboxy;
- X and Y represent independently chloro, hydroxy, an alkoxy group, phenoxy which may be substituted with the substituents selected from the group consisting of sulfo, carboxy, acetylamino, amino, and hydroxy, a mono- or di-alkylamino group having sulfo or carboxy, anilino which may be substituted with one or two substituents selected from the group consisting of sulfo and carboxy, naphthylamino, the naphthyl may be substituted with sulfo, or a mono- or di-alkylaminoalkylamino group, except that X and Y are respectively any groups selected from the group consisting of chloro, hydroxy and anilino which may be substituted with one or two substituents selected from the group consisting of sulfo and carboxy, if R2 is hydrogen.
A novel anthrapyridone compound represented by Formula (1) or the salt thereof:
- or Formula (2) or the salt thereof:
- wherein R1 is hydrogen or methyl;
- R2 is hydrogen, methyl, ethyl, phenoxy which may be substituted, sulfo or carboxy;
- X is anilino having two carboxy groups;
- and Y is hydroxy, anilino having two sulfo groups, an alkylamino group having sulfo or carboxy, or a dialkylaminoalkylamino group.
An anthrapyridone compound represented by Formula (5) as shown below:
- wherein, R1 is hydrogen, an alkyl group, a hydroxy lower alkyl group, cyclohexyl, a mono- or di-alkylaminoalkyl group, or a cyano lower alkyl group;
- and R2 is hydrogen, methyl, ethyl, phenoxy which may be substituted, sulfo or carboxy;
- except that if R1 is hydrogen or methyl, R2 is hydrogen.
