1. An overcoat liquid for inkjet textile printing, comprising:
particles of an anionic polyurethane;
particles of a wax;
a water-soluble organic solvent; and
water,
wherein a content of the particles of the anionic polyurethane is 4 mass % to 20 mass % relative to a total amount of the overcoat liquid,
a content of the particles of the wax is 0.1 mass % to 3 mass % relative to the total amount of the overcoat liquid, and
a content of the water-soluble organic solvent satisfies formula (1) in units of mass %:
0.7×A+0.8×B+C<20  (1)
A: a content of a water-soluble organic solvent having a boiling point of 200° C. or lower relative to the total amount of the overcoat liquid,
B: a content of a water-soluble organic solvent having a boiling point of higher than 200° C. and 250° C. or lower relative to the total amount of the overcoat liquid, and
C: a content of a water-soluble organic solvent having a boiling point of higher than 250° C. relative to the total amount of the overcoat liquid,
wherein a ratio of the content of the particles of the anionic polyurethane to the content of the particles of the wax is 25 to 50 on a mass basis.
