Abstract

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.

A dispersion composition, comprising:

(A) a modified polyolefin resin;
and
(B) a dispersing medium comprising an alcohol solvent and an aliphatic hydrocarbon solvent,
wherein the modified polyolefin resin (A) is dispersed in the dispersing medium (B),
wherein the modified polyolefin resin (A) is modified by a (meth)acrylic acid component comprising
(C) a (meth)acrylate ester of formula (I):
CH2═C(R1)COOR2 (I),
R1 being H or a methyl group;
and R2 being —CmH2mOH, with m being an integer in a range of from 1 to 18;
and
(D) a (meth)acrylic ester of formula (II):
CH2═C(R3)COOR4 (II),
R3 being H or a methyl group;
and R4 being a linear, a branched, and/or a cyclic alkyl group having 4 to 18 carbon atoms,
wherein a total content of a structure derived from the (meth)acrylic acid component in the dispersion composition is in a range of from 3 to 94 wt. %, relative to 100 wt. % as a total amount of the modified polyolefin resin (A) and (meth)acrylic acid component polymer, and
wherein a solid fraction in the dispersion composition is in a range of from 30 to 80 wt. %.
