ABSTRACT:
A recording liquid capable of giving a printed matter which is high in printing density, is suppressed in blur, has high printing quality, and has good fastness of a recorded matter including light fastness, water fastness and the like and having a low viscosity, good discharge properties and excellent storage stability. The invention is concerned with a polyvinyl alcohol based block copolymer represented by the following general formula (1), a pigment dispersion aqueous liquid containing this polyvinyl alcohol based block copolymer and a pigment in an aqueous medium, and a recording liquid containing this pigment dispersion aqueous liquid.wherein A, B, X1, X2, X3, X4, m1, and m2have the same meanings as defined in the specification.
