A nonaqueous ink composition contains organic solvents. The organic solvents include an organic solvent (a) and an organic solvent (b). Organic solvent (a): Glycol ether dialkyl. Organic solvent (b): At least one selected from the group consisting of alkylamide-based solvents (b1), cyclic amide-based solvents (b2), and lactone-based solvents (b3) each having a ring including six or more members.

Nonaqueous ink composition, and recording method and recorded matter manufacturing method using same

A non-aqueous ink composition which has superior printing performance, such as continuous discharge stability, and also has excellent storage stability and excellent coloring properties, and with which printed matter having superior durability can be obtained. A non-aqueous ink composition discharged using an inkjet method, the composition containing an organic solvent, a colorant, and a resin, where the resin contains at least one resin selected from the group consisting of acrylic resins, vinyl chloride-vinyl acetate copolymer resins, and cellulose resins, and a resin having intrinsic viscosity at 25° C. of 90 mL/g or more accounts for up to 5 mass % of the entire resin.

Non-aqueous ink composition, inkjet recording method, and method for manufacturing printed matter

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.

Receptive solution, ink set containing said receptive solution and method for producing printed material using ink set

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, Rrepresents an optionally branched alkylene group having 1 to 5 carbon atoms (inclusive); Rrepresents a hydrogen atom or an optionally branched alkyl group having 1 to 3 carbon atoms (inclusive); Rrepresents 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).
