Release coating compositions for pressure sensitive adhesive articles and methods

A method of making a release coated article comprising:

• providing a coating composition comprising:
• one or more monomers, each monomer comprising an ethylenically unsaturated group and a terminal alkyl group with at least 18 carbon atoms;
• one or more crosslinking components, each crosslinking component comprising at least two ethylenically unsaturated groups;
• optionally other ethylenically unsaturated monomers, oligomers, or polymers;
• and
• a polymerization initiator;
• wherein the coating composition comprises at least 50 wt. % of the monomer(s) comprising an ethylenically unsaturated group and a terminal alkyl group with at least 18 carbon atoms that is solid at 25° C. based on the total ethylenically unsaturated monomers, crosslinking components, and when present other ethylenically unsaturated monomers, oligomers, or polymers;
• wherein the coating composition comprises no greater than 1 wt. % of organic solvent;
• applying the coating composition to a surface of a substrate at a temperature above the melting temperature of the coating composition;
• polymerizing the one or more monomer(s) comprising an ethylenically unsaturated group and a terminal alkyl group with at least 18 carbon crosslinking component(s), and when present other ethylenically unsaturated monomers, oligomers, or polymers of the coating composition after applying the coating composition to the substrate, thereby forming a polymerized release coating on the substrate.
