Abstract: Described herein are shaped articles comprising a monolayer of microspheres partially embedded in its surface. The shaped articles are made via a transfer article (20), which comprises a microsphere monolayer (22) comprising a plurality of microspheres partially embedded in a first major surface of a transfer polymer layer (23), which is disposed on a support layer (21). The transfer article is shaped and a conformable substrate is contacted with the shaped transfer article, transferring the microspheres to the conformable substrate forming a shaped finished article having a surface comprising a monolayer of partially embedded microspheres.

Abstract: Wet-on-wet coating processes are provided to produce multilayer articles. First and second coating materials are sequentially applied on to a structured substrate surface to form a skin layer directly over the structured substrate surface and a bulk layer over the skin layer. The conformability of the skin layer can be adjusted to provide desired surface and bulk properties.
