Abstract:
Described herein is a construction comprising a microsphere layer comprising a plurality of microspheres wherein the microspheres comprise glass, ceramic, and combinations thereof; a first polymer layer comprising a first polymer, wherein the plurality of microspheres is partially embedded in the first polymer layer; and an undercoat layer therebetween the microsphere layer and first polymer layer, wherein the undercoat layer comprises a plurality of silica nanoparticles. Also disclosed herein are articles comprising the construction and methods of making thereof. In one embodiment, the constructions of the present disclosure have good anti-soiling and abrasion resistant properties.
Abstract:
There is provided an article comprising at least a first surface having a first binder layer selected from at least one of linear resins and resins having low cross link densities, where the first binder layer has a first major surface opposite a second major surface; and a plurality of microspheres at least partially embedded in the first major surface of the first binder layer. For at least a portion of the first major surface, the plurality of micro spheres may cover 30% to 50% of that portion, and the microspheres may be substantially uniformly spaced.
