Flexible microsphere articles having high temperature stability

An article comprising:

• (a) a binder resin layer comprising an aliphatic polyurethane polymer comprising a plurality of soft segments, and a plurality of hard segments, wherein the soft segments comprise poly(alkoxy) polyol, and wherein the poly(alkoxy) polyol is essentially free of crosslinker;
• and
• (b) a plurality of microspheres wherein the plurality of microspheres consists essentially of glass, glass ceramics, ceramics, or combinations thereof, wherein each microsphere is partially embedded and adhered to a first major surface of the binder resin layer,
• wherein the aliphatic polyurethane polymer has a glass transition temperature of 10° C. or less and the binder resin layer has a storage modulus that changes less than 15 MPa from 25° C. to 175° C., the portion of each microsphere partially embedded in the first major surface of the binder resin layer, and at least about 60% of the first major surface of the binder resin layer is covered with the plurality of microspheres is in direct contact with the binder resin layer.
