Composition including monomer with a carboxylic acid group, monomer with a hydroxyl group, an alkyl monomer, and crosslinker and related article and method

A composition comprising:

• an acrylic monomer comprising a carboxylic acid group;
• at least one of an alkyl acrylate or alkyl methacrylate;
• an acrylic monomer comprising a hydroxyl group;
• and
• a compound comprising divalent segments L and at least two X groups in an amount from 15 percent to 22 percent by weight, based on the total weight of acrylic-functional compounds in the composition, wherein the divalent segments L are represented by the formula:
• wherein each divalent segment L is independently directly bonded to:
• i) two secondary N atoms, each directly bonded to a further divalent segment L or an X group,
• ii) two tertiary N atoms, each directly bonded to p further divalent segments L and (2-p) X groups, wherein p is 0, 1, or 2, or
• iii) a secondary N atom directly bonded to a further divalent segment L or an X group;
• and a tertiary N atom directly bonded to p further divalent segments L and (2-p) X groups, wherein p is 0, 1, or 2,
• wherein each R1 independently represents an alkylene group having from 1 to 4 carbon atoms, with the proviso that at least some of the R1 groups are —CH2—CH2—CH2—CH2—, wherein each n independently represents a positive integer, and wherein each X group is independently represented by the formula
• CH2═C(R)—C(O)—O—V—W—C(O)—
• wherein each R is independently hydrogen or methyl, each W is independently O, S, or NR2, wherein R2 is hydrogen or alkyl having up to 4 carbon atoms, and wherein each V is independently alkylene that is optionally interrupted by at least one ether linkage or amine linkage and optionally substituted by hydroxyl.
