    Abstract: Release liners that can be included in various adhesive products are provided. A first release liner is a layer of a composition including a) a polymeric material having at least one hydrogen atom covalently bonded to an oxygen atom, a nitrogen atom, or a sulfur atom; and b) a silicone polyether comprising at least one of polyoxoethylene units or polyoxopropylene units. A second release liner includes a substrate and a coating of the above composition disposed on a major surface of the substrate. The present disclosure also provides an article including one of the above release liners and an adhesive layer disposed on a major surface of the release liner. The composition of the release liner can advantageously be dissolved and optionally recycled.

    Abstract: Article comprising, in order: a first polymeric film having first and second, opposed major surfaces; a first primer layer having first and second opposed, major surfaces on the first major surface of the first polymeric film, wherein for a distance of at least 25 nm starting from the first major surface of the first 5 primer layer toward the second major surface of the first primer layer there is an average Si content, on a theoretical elemental basis, not greater than 15 atomic percent; and a first release layer having first and second opposed, major surfaces, wherein the second major surface of the first release layer is in direct contact with the first major surface of the first primer layer, wherein the first release layer comprises, on a theoretical elemental basis, Si. Articles described herein are useful, for example, as a release liner for 10 casting pressure sensitive adhesives thereon.
