Abstract of corresponding document: WO2015100194 (A1)

A composition suitable for use as a low adhesion backsize or a primer for low surface energy adhesives, including the reaction product of at least one moisture-curable, semi-crystalline (meth)acrylic oligomer represented by the formula: wherein R1 is independently a C16 to C40 alkyl group; R2 is independently a C1 to C40 alkyl group; each R3 is independently a methyl, ethyl, or isopropyl group; X is a chain transfer agent as defined further below; Y is independently selected to be a methyl, ethyl, or isopropyl group; a, b and c are each independently selected to be an integer of at least 10, and a + b + c < 1500; n > 1; and p is 0, 1, 2, or 3. Articles and methods of using the composition as a low adhesion backsize or a primer for a low surface energy adhesive are also described.
