Aqueous coloring composition for textile printing, textile printing method, and fabric

An aqueous coloring composition for textile printing, the aqueous coloring composition comprising a colorant and water, wherein:

• a molecule of the colorant comprises a chromophoric group and a dissociable group that is in a dissociated state;
• the chromophoric group and a negative electric charge, generated by dissociation of the dissociable group, form a conjugated system;
• and
• a number of the dissociable groups in the molecule of the colorant is the same as a number of the chromophoric groups in the molecule;
• and wherein
• the colorant is an azo dye represented by the following Formula 1-1:
• wherein, in Formula 1-1, D1 represents a cyclic hydrocarbon group or a heterocyclic group may have a substituent;
• E represents a hydrogen atom, an acylamino group, or an electron withdrawing group;
• the benzene ring shown in Formula 1-1 may be condensed with a ring including X1 as a component;
• G represents a substituent that bonds to the benzene ring shown in Formula 1-1 or the condensed ring including X1 as a component;
• m represents an integer from 0 to 4;
• W1 represents an anionic substituent selected from —O−, —S−, —N−(R1), and —C−(R1)(R2), and each of R1 and R2 independently represents an electron withdrawing group having a Hammett σp value of 0.30 or higher.
