Abstract: The present invention provides a modified polyolefin resin composition including 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 the following (I) to (III) and also provides applications of the modified polyolefin resin composition.
(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.
(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.

Abstract: A resin composition can be used as a raw material of a primer, and capable of superior solution stability, adhesion to a non-polar substrate, and/or chipping resistance in a coating film formed from the composition. The resin composition includes a component A: a modified polyolefin resin, and a component B: a polymer having a functional group at least in a terminal thereof, and having a number-average molecular weight in a range of 1,000 to 20,000, and containing a constituent unit (i) derived from a (meth)acrylate ester of a formula, CH2═C(R1)COOR2, wherein R1 is a hydrogen atom or a methyl group, R2 is a —CnH2n+1 group, and n is an integer of 1 to 18)
