1. A composition comprising:
at least 20 percent by weight, based on the total weight of acrylic-functional compounds in the composition, of an acrylic monomer comprising a carboxylic acid group;
an acrylic monomer comprising a hydroxyl group; and
a compound comprising divalent segments L and at least two X groups, wherein the divalent segments L are represented by the formula:

OG Complex Work Unit Chemistry
wherein each divalent segment L is respectively directly bonded to:
i) two secondary N atoms, each directly bonded to a further divalent segment L or an X group, or
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, wherein 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.
