An object to be achieved by the present invention is to provide a textile printing agent which has less coarse particles and which forms a printed portion having excellent printing properties, especially excellent fastness to washing and excellent fastness to rubbing. The present invention is directed to a textile printing agent which contains a polyhalogenated metallophthalocyanine pigment or a diketopyrrolopyrrole pigment, water, an organic solvent, a binder resin, and, as a pigment dispersant, a polymer (A) having an anionic group, a solubility in water of 0.1 g/100 ml or less, and a number average molecular weight of 1,000 to 6,000, wherein the polymer (A) forms fine particles in water when the polymer (A) is neutralized such that the neutralization rate of the anionic group by a basic compound is 100%.
