Abstract: An object of the present invention is to provide an active energy ray-curable lithographic printing ink set that is excellent in superimposition of inks, and a method for producing a printed material using the same.
The present invention is an active energy ray-curable printing ink set including at least one ink of black or chromatic color including at least any one of a black pigment, a cyan pigment, a magenta pigment, and a yellow pigment, and a white ink including a white pigment, wherein at least one of the ink of black or chromatic color is the black/chromatic ink (1) having a tack value of 5.0 or more and 12.0 or less at 400 rpm measured with an inkometer at 38° C., and the white ink has a tack value of 1.0 or more and 5.0 or less at 400 rpm measured with an inkometer at 38° C.

Abstract: An object of the present invention is to provide a resin that is superior in low tackiness and anti-scumming property at the time of printing and also superior in hot water treatment resistance after printing, an active energy ray-curable composition, an active energy ray-curable ink, an overcoat varnish, a paint, an adhesive, a photoresist, and a method for producing a printed matter. The present invention is a resin that is a copolymer of a monomer group including a styrene-based compound (a) and a vinyl monomer (c) having a hydrophilic group, wherein a content of the styrene-based compound (a) in the monomer group is 50.0 mol % or more and 85.0 mol % or less, and the resin has a glass transition temperature (Tg) of 100° C. or more and 150° C. or less.
