A method of making a release coated article is described comprising: providing a release coating comprising at least 50 wt. % of monomer(s) comprising an ethylenically unsaturated group and a terminal alkyl group with at least 18 (e.g. contiguous) carbon atoms based on the total amount of ethylenically unsaturated components; crosslinking components(s) comprising at least two ethylenically unsaturated groups; and at least one polymerization initiator. The release coating is substantially solventless, comprising no greater than 1 wt. % of non-polymerizable organic solvent. The method further 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 after applying the release coating to the substrate. Also described are release coating compositions.
