Abstract
A method of forming a transfer film is described. The transfer film includes a template layer having a first major surface and an opposing second major surface. The second major surface includes a structured non-planar release surface. A backfill layer is disposed upon and conforms to the non-planar structured surface. The backfill layer includes a first cross-linked polymer and a plurality of multifunctional monomers, which cure via different and independent curing mechanisms.
