Ink composition for an inkjet, a recorded material, and a recording method with an inkjet

Abstract

[Problem] An object of the present invention is to provide an ink composition for inkjet printing that imparts a printed layer that is excellent in terms of tactile sensation, abrasion resistance, and adherence to a substrate, a printed material and a recorded material that have an ink layer formed from the ink composition, and an inkjet recording method. [Solution] An ink composition comprising the following components (A), (B) and (C), (A) an emulsion of a silicone acrylic copolymer resin in an amount of 0.5 to 20 parts by mass as a solid content, (B) an emulsion of a urethane resin in an amount of 10 to 79.5 parts by mass as a solid content, and (C) pigment in an amount of 20 to 89.5 parts by mass, provided that a total mass of the solid content of components (A) and (B) and component (C) is 100 parts by mass, wherein component (A) is an emulsion of a copolymer of (a1) a polyorganosiloxane represented by the following formula (1) in an amount of 60 to 99 parts by mass with (a2) an acrylic acid ester monomer and/or a methacrylic acid ester monomer in an amount of 1 to 40 parts by mass, provided that a total amount of components (a1) and (a2) is 100 parts by mass, wherein R1 is, independently of each other, a substituted or unsubstituted monovalent hydrocarbon group having 1 to 20 carbon atoms, precluding the groups defined for R2 and a phenyl group; R2 is, independently of each other, an alkenyl group having 2 to 6 carbon atoms or an alkyl group having 1 to 6 carbon atoms and of which a part of the hydrogen atoms bonded to the carbon atom is substituted with a mercapto group, a vinyl group, an acryloxy group, or a methacryloxy group; R3 is, independently of each other, a phenyl group or the group defined for R1, and at least one of R3s bonded to the silicon atom is a phenyl group; and X is, independently of each other, a substituted or unsubstituted monovalent hydrocarbon group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, or a hydroxyl group; and a, b, c and d are the number satisfying equations: 0.11≤a/(a+b+c+d)<1, 0.00001≤b/(a+b+c+d)≤0.05, 0≤c/(a+b+c+d)≤0.6, and 0.000001≤d/(a+b+c+d)≤0.24, based on the total number of a, b, c and d.
