Abstract: An adhesive article attachable to a substrate may include an adhesive layer attachable to a major surface of a substrate and a releasable liner in contact with the adhesive layer. The releasable liner has a release layer and a biodegradable polymer layer applied to the release layer. The release layer defines a structured surface in contact with the adhesive layer.

Abstract: Described herein is a release coating comprising a blend of: (a) a first polymer, wherein the first polymer is a silicone-containing (meth)acrylic polymer; and (b) a second polymer, wherein the second polymer comprises the polymerization reaction product of: (i) a first monomer having an alkyl group with 12 to 24 carbon atoms, a linking group containing a nitrogen or ester group, and a free-radically polymerizable (meth)acryl group; and (ii) a second free-radically polymerizable monomer having less than 12 carbon atoms. Such release coatings can be coated onto a substrate and used as a release coating for pressure sensitive adhesives.

Abstract: A release composition comprising a waterborne latex polymer particles comprising the polymerization reaction product of: i) a first monomer having an alkyl group with 12 to 24 carbon atoms, a nitrogen-containing or ester linking group, and a free-radically polymerizable (meth)acryl group; ii) a second free-radically polymerizable monomer having less than 12 carbon atoms; and iii) a free-radically polymerizable surfactant; and an aqueous carrier liquid. Also described is a method of making a release coated article and articles.
