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.
