Abstract
This dispersion-type acrylic copolymer has a matrix (I) formed of an acrylic copolymer having a glass transition temperature of 50° C. or higher and a polymer unit (II) formed of an acrylic copolymer having a glass transition temperature of less than 50° C., the polymer unit (II) forms localized regions having an average diameter of 5-300 nm in the matrix (I), the matrix (I) and polymer unit (II) contain units of a crosslinking component, and the content of these units of a crosslinking component is more than 2% by mass relative to the total weight of the acrylic copolymer.
