    Abstract: A method of making a release coated article is described comprising: providing a release coating composition comprising at least 50 wt.% of a mixture of ethylenically unsaturated monomers based on the total ethylenically unsaturated components; wherein the mixture comprises monomer(s) with a linear alkyl group with at least 18 carbon atoms, and monomer(s) with a branched alkyl group with 7 to 31 carbon atoms, and crosslinking component(s) comprising at least two ethylenically unsaturated groups. The method comprises applying the release coating to a major surface of a substrate and polymerizing the monomer(s) and crosslinking component(s) of the release coating. The monomer(s) with linear alkyl groups and branched alkyl groups are typically present at a weight ratio such that the release coating is a liquid at 25°C. Also described are release coating compositions and articles.
