摘要： The present invention provides a modified polyolefin resin that can form a coating that exhibits excellent adhesion to a low-polarity base material, especially a poorly adherable polyolefin base material with no surface treatment even when being dried at low temperatures and has flexibility (bendability). Provided is a modified polyolefin resin that is a modified product of a polyolefin resin having a melting point (Tm) by a differential scanning calorimeter (DSC) of 60 to 165°C with a modifier comprising the following (A):
(A) a monomer mixture comprising Monomer Group (A-1) and Monomer Group (A-2) with a weight ratio of Monomer Group (A-1) to Monomer Group (A-2) ((A-1)/(A-2)) of 30/70 to 50/50.-

摘要： An object of the present invention is to provide an alcohol-based composition containing an acryl-modified polyolefin resin that exhibits a good adhesion even at a high solid content, that suppresses an increase in viscosity, and that has good stability such as dispersibility and sustainable stability. The present invention relates to a dispersion composition in which at least a modified polyolefin resin is dispersed in a dispersing medium containing an alcohol solvent and an aliphatic hydrocarbon solvent. The modified polyolefin resin is modified with a (meth)acrylic acid component containing at least a (meth)acrylic ester represented by the following general formula (I) and a (meth)acrylic ester represented by the following general 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.
