Recording liquid
First Claim
1. An ink-jet recording liquid comprising an aqueous medium and at least one dye selected from the group consisting of dyes, the free acid forms of which are represented by general formula {I}:
- ##STR6## wherein R1, R2, and R3 each independently represents a substituted or unsubstituted alkyl group having 1 to 9 carbon atoms, a halogen atom, a hydrogen atom, a hydroxyl group, a substituted or unsubstituted carbamoyl group, a substituted or unsubstituted sulfamoyl group, a substituted or unsubstituted amino group, a nitro group, a sulfonic ester group, a sulfonyl group, a COOH group, or a carboxylic ester group;
m represents a number of 0, 1, or 2; and
R4, R5, R6, and R7 each independently represents a hydrogen atom, an alkyl group having 1 to 18 carbon atoms, an alkenyl group having 1 to 18 carbon atoms, an aryl group, an aralkyl group, an alicyclic group, or a heterocyclic group, and each may have a substituent when not representing a hydrogen atom, provided that at least one of R4, R5, R6, and R7 represents a group having a COOH group as a substituent;
wherein the at least one dye is suitable for ink-let recording.

Abstract
The present invention relates to a recording liquid characterized by comprising an aqueous medium and at least one monoazo dye selected from dyes, the free acid forms of which are represented by general formula {I}: ##STR1## (wherein R1, R2, and R3 each independently represents a substituted or unsubstituted alkyl group having 1 to 9 carbon atoms, an alkoxy group having 1 to 9 carbon atoms, a halogen atom, a hydrogen atom, a hydroxyl group, a substituted or unsubstituted carbamoyl group, a substituted or unsubstituted sulfamoyl group, a substituted or unsubstituted amino group, a nitro group, a sulfonic ester group, a sulfonyl group, a COOH group, or a carboxylic ester group;
m represents a number of 0, 1, or 2; and
R4, R5, R6, and R7 each independently represents a hydrogen atom, an alkyl group having 1 to 18 carbon atoms, an alkenyl group having 1 to 18 carbon atoms, an aryl group, an aralkyl group, an alicyclic group, or a heterocyclic group, and each may have a substituent when not representing a hydrogen atom, provided that at least one of R4, R5, R6, and R7 represents a group having a COOH group as a substituent).
