ARTICLES HAVING A MULTILAYER STRUCTURE INCLUDING UNDERCUT FEATURES INTERLOCKED WITH AN ADHESIVE AND METHODS OF MAKING SAME

摘要

(a) a first layer comprising undercut features formed on and extending from an integral backing and formed of a polyolefin; (b) a second layer comprising an adhesive having a Shore D hardness greater than 59 when cured; And (c) a third layer comprising a substrate. The second layer is interlocked with the undercut features, the third layer is bonded to the adhesive, and the second layer is disposed between the first and third layers. (a) placing a polyolefin resin within a mold cavity to form a first layer comprising undercut features; (b) demoulding the first layer at a rate of at least 150 millimeters per minute from the mold cavity; (c) applying a curable adhesive to the undercut features to form a second layer attached to the first layer; And (d) attaching a third layer comprising a substrate to the second layer.
