Abstract:
There is provided an article a binder resin layer comprising an aliphatic polyurethane polymer comprising a plurality of soft segments, and a plurality of hard segments, where the soft segments comprise poly(alkoxy) polyol, and where the poly(alkoxy) polyol is essentially free of crosslinker; and a plurality of microspheres partially embedded and adhered to a first major surface of the binder resin layer, wherein the specific chemical identities and relative amounts of the segments and moieties of the aliphatic polyurethane polymer are sufficient to impart a glass transition temperature of 10° C. or less in the article and a storage modulus in the article that changes less than 15 MPa from 25° C. to 175° C.
