An aqueous composition that can be used to provide a release release properties to adhesive tape substrates can be applied at coating weights far less than those required in previously available compositions containing the same or similar release polymers. Inclusion of small amounts of a superwetter results in improved coatability and reduced amounts of sound generated during the process of releasing an adhesive tape from its roll.

Provided here is a release coating composition, comprising of at least one polymer binder and one or more micro-beads, wherein the amount of the micro-beads is in the range of 1 vol % to 85 vol % of the total dry volume of the release coating composition. The release coating composition enables recycling of release liner substrates provides high quality printing and utilizable in self-wound label laminate construction with no liner.

An adhesive film liner comprising (a) a polymeric layer having a first and a second surface, the second surface being opposed to the first surface; (b) a first release layer located on top of the first surface of the polymeric layer, the first release layer comprising at least one polyurethane acrylate oligomer and/or at least one polyurethane methacrylate oligomer; and (c) a second release layer located on top of the second surface layer of the polymeric layer, the second release layer comprising at least one acrylate polymer.

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.
