Abstract: Provided is a printing agent including a pigment, a pigment dispersant, water, an organic solvent, and a binder resin, the pigment dispersant being a polymer (A) including an anionic group, the polymer (A) having a solubility in water of 0.1 g/100 ml or less, a number-average molecular weight of 1000 to 6000, and an acid value of 40 to 400 mgKOH/g. Also provided is a printed fabric produced by applying the printing agent on a fabric. The polymer (A) is preferably a polymer represented by General Formula (1) (where A1 represents a residue of an organolithium initiator; A2 represents a polymer block including a monomer having an aromatic ring or a heterocyclic ring; A3 represents a polymer block including an anionic group; n represents an integer of 1 to 5; and B represents an aromatic group or an alkyl group).
