摘要： An object is to provide a resin composition having excellent performance as a binder such as adhesiveness and, at the same time, retaining solution properties favorably even after a solution is stored for a long period of time. A modified polyolefin resin composition includes a modified polyolefin resin (C), in which the modified polyolefin resin (C) is a resin made by modifying a polymer (A) that is a polymer (a) of a polyolefin resin or a chlorinated polyolefin resin and an α,β-unsaturated carboxylic acid derivative having a structure derived from at least one carboxy group or a chlorinated product (b) thereof with a modification component including an alcohol (B); and a residual ratio of the structure derived from at least one carboxy group in the modified polyolefin resin (C) is 50% or more and 80% or less.

摘要： An alcohol-based composition may contain an acryl-modified polyolefin resin and exhibit a good adhesion even at a high solid content, suppress an increase in viscosity, and have good stability such as dispersibility and sustainable stability. A dispersion composition may contain at least a modified polyolefin resin dispersed in a dispersing medium containing an alcohol solvent and an aliphatic hydrocarbon solvent. The modified polyolefin resin may be modified with a (meth)acrylic acid component containing at least a (meth)acrylic ester of formula (I) and a (meth)acrylic ester of formula (II). The total content of the structure derived from the (meth)acrylic acid component in the dispersion composition is 3% to 94% by weight, relative to 100% by weight as a total amount of the modified polyolefin resin and (meth)acrylic acid component polymer, and a solid fraction in the dispersion composition is 30% to 80% by weight.

摘要： 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)
