Abstract: The purpose of the present invention is to provide a receptive solution which can suppress the occurrence of odor from the receptive solution itself when the receptive solution is applied on a recording medium, and can also prevent the appearance of a printed surface from being deteriorated. The receptive solution for ink-jet recording ink contains polyvalent metal cations, an aqueous solvent, a resin, and anions, wherein the resin is contained as a resin emulsion, and the anions contained in the receptive solution contain anions of an organic substance which has an OV/IV value of 0.3-1.0, the OV/IV value being a ratio of an organic value to an inorganic value.

Abstract: This receiving solution for inkjet recording inks contains a resin emulsion as the resin; the polyvalent metal salt contains ions of a polyvalent metal and anions of an organic material; the (organic value)/(inorganic value) ratio, namely the OV/IV value of the anions of the organic material is 0.25 or more but less than 1.30; the HLB value of the surfactant is from 9 to 19 (inclusive); and the surfactant is represented by general formula (1). (In the formula, R1 represents an optionally branched alkylene group having 1 to 5 carbon atoms (inclusive); R2 represents a hydrogen atom or an optionally branched alkyl group having 1 to 3 carbon atoms (inclusive); R3 represents a hydrogen atom or an optionally branched alkyl group having 1 to 3 carbon atoms (inclusive); A represents 2 or 3; X represents ethylene oxide and/or propylene oxide; and n represents an integer).
