  • Patent number: 10563081
    Abstract: A main object of the present invention is to provide an ink composition for ink-jet recording capable of forming an ink film excellent in both film strength and scratch resistance. The present invention achieves the object by providing an ink composition for ink-jet recording comprising: an aqueous solvent including water and water-soluble organic solvent; a coloring agent; a resin emulsion; and a surfactant; wherein the resin emulsion includes a silicon-acrylic resin emulsion and a resin emulsion other than the silicon-acrylic resin emulsion; a content ratio of the resin emulsion to the coloring agent (content of the resin emulsion/content of the coloring agent) is 1/5 or more and 15/1 or less; and a content ratio of the silicon-acrylic resin emulsion to the coloring agent (content of the silicon-acrylic resin emulsion/content of the coloring agent) is 1/20 or more and 5/1 or less.

  • Publication number: 20200040207
    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.

  • Patent number: 9944810
    Abstract: Provided is an aqueous ink jet-use ink composition which includes a binder resin, a surfactant, a pigment, a solvent and, if necessary, a pigment-dispersing resin. The binder resin has a glass transition temperature of 40-90° C. and is dispersed as resin emulsion particles. The value of A, which is defined as the sum of the product of the acid value and the content in terms of parts by mass of the binder resin and pigment-dispersing resin, is 0-200 mg KOH/g. The surfactant is a non-ionic compound represented by formula (1), and the content of solvents having boiling points of 250° C. or higher is less than 5 parts by mass relative to 100 parts by mass of the ink composition. R1O—(R2O)n—H??(1) R1 is a straight-chain or branched chain alkyl group having 12-22 carbon atoms. R2 is an ethylene group or propylene group. n is an integer between 10 and 50.
