Abstract
To provide an aqueous matte ink composition for gravure printing or flexographic printing that has excellent adhesion to polyolefin films, acid resistance, blocking resistance, and abrasion resistance that can withstand friction with rubber, and also has excellent storage stability, as well as laminates and packaging materials using the same. [Solution] An aqueous matte ink composition for gravure printing or flexographic printing, comprising (meth)acrylic resin emulsion (A), modified polypropylene resin emulsion (B), matting agent (C), and aqueous medium (D), wherein the acid value of (A) is 60 mgKOH / g or less, the average particle size is 0.038 to 0.300 μm, the acid value of (B) is 60 mgKOH / g or less, the difference between the acid value of (A) and the acid value of (B) satisfies a specific relational expression, the content of (B) is 1.0 to 10.0 mass%, and the mass ratio in terms of solid content expressed as (B) / (A) is 0.050 to 0.500.
