| abstract |
The present invention provides an aqueous dispersion which contains the component (A) and the component (B) described below, and which is configured such that the mass ratio of the content of the component (A) to the content of the component (B), namely (content of component (A))/(content of component (B)) is from 55/45 to 95/5. Component (A): a polyolefin which is modified with an α, β-unsaturated carboxylic acid and/or a derivative thereof, and which has a weight average molecular weight of 100,000 or more, a crystallinity of more than 10% and an acid value of 1-30 mgKOH/g Component (B): a polyolefin which is modified with an α, β-unsaturated carboxylic acid and/or a derivative thereof, and which has a weight average molecular weight of less than 100,000 and an acid value of 15-50 mgKOH/g |
