1. A release composition comprising a waterborne latex polymer particles comprising a polymerization reaction product of:
i) a first monomer having
the formula
CnH2n+1—Y—CmH2m—X—CR1═CH2
wherein n ranges from 12 to 24;
Y is a nitrogen-containing or ester linking group;
R1 is hydrogen or methyl;
m ranges from 2 to 10; and
X is a divalent linking group selected from ester or amide;
ii) a second free-radically polymerizable monomer having less than 12 carbon atoms;
iii) a free-radically polymerizable surfactant; and
an aqueous carrier liquid.
