A modified polyolefin resin composition may include a modified polyolefin resin (X) formed by modifying an acid-modified polyolefin resin (A) with a modification component comprising an alcohol (B), in which the modified polyolefin resin composition satisfies (I) to (III): (I) the resin (A) is a resin formed by modifying a polyolefin (a) with an α,β-unsaturated carboxylic acid and a derivative (b) of the α,β-unsaturated carboxylic acid having a structure (b1) derived from at least one carboxy group; (II) a residual ratio of the structure (b1) in the resin (X) is more than 0% to 50% or less; and (III) a content of the alcohol in the composition is 1.0 mol to 5.0 mol relative to 1.0 mol of the structure (b1) that the resin (A) has.

Modified polyolefin resin composition

Provided is a resin composition having a large proportion of polyolefin components, allowing preparation of a solution having a high solid content, having a good solution property after long-term storage, having good pigment dispersibility, and including a modified product of component (A): polyolefin resin with component (B): (meth)acrylic acid and/or (meth)acrylic acid ester, in which the weight ratio of the component (A) to the component (B) ((A)/(B)) is 90/10 to 30/70, and the component (B) contains 20% by weight or more of component (B1): an alkoxy (poly)alkylene glycol mono(meth)acrylic acid ester.
