Abstract
The composition includes an acrylic monomer having a carboxylic acid group, an acrylic monomer having a hydroxyl group, and a compound composed of divalent segments L and at least two X groups. The divalent segments L are represented by the formula Each divalent segment L is respectively directly bonded to two secondary N atoms, two tertiary N atoms, or a secondary and a tertiary N atom. Each Rrepresents an alkylene group having from 1 to 4 carbon atoms, and at least some of the Rgroups are —CH—CH—CH—CH—. Each X group is independently represented by the formula CH═C(R)—C(O)—O—V-W—C(O)—. The acrylic monomer having a carboxylic acid group is present in an amount of at least 20 percent by weight, based on the total weight of acrylic-functional compounds. Articles and a method of using the composition are also described.
