• (a) at least one organic diol monomer;
• (b) at least one organic diacid monomer, at least one diester monomer or mixtures thereof;
• (c) at least one carbinol terminated polydimethylsiloxane, at least one carboxy terminated polydimethylsiloxane, or mixtures thereof;
• and
• (d) at least one ion salt of a sulfonate difunctional monomer;
• (ii) a water-soluble or water-dispersible second polymer;
• and
• (iii) a thermally activated curing system comprising a multifunctional compound wherein the multifunctional compound comprises at least one of melamine, diazine, urea, cyclic ethylene urea, cyclic propylene urea, thiourea, cyclic ethylene thiourea, alkyl melamines, aryl melamines, benzo guanamines, guanamines, alkyl guanamines, aryl guanamines with an aldehyde, and combinations thereof and wherein the release coating composition is aqueous.
