Patent
Optical film coating
TL;DR: In this article, a low fringing transparent polymeric (LFP) film is constructed by coating a polymeric composition onto a substrate with a good solvent for the polymeric material and a poor solvent for either the material or the solvents.
Patent
Coating edge control
TL;DR: In this paper, methods and products prepared from the methods, each of which include methods of coating certain materials onto a substrate, including coating a coating material and an edge material onto the substrate in a manner which may provide an improved thickness profile of the overall coating, and that may do so by using the edge material to augment the thickness of the coating material edge.

TL;DR: In this article, a light redirecting film is disclosed, which includes a first major surface that includes a plurality of first microstructures that extend along a first direction and an optical haze that is in a range from about 4% to about 20%.
Patent
Apparatus and method for drying a coating on a substrate
TL;DR: In this paper, the first heat transfer rate is created by a first heat-transfer coefficient and a first temperature difference between the first coating temperature and the first drying gas temperature, which causes maximum evaporation of the coating solvent yet insignificant formation of mottle.
Patent

TL;DR: In this paper, a micro-replicated tool was used to construct a high refractive index layer (60) and low refractive indices (80) for antireflective films with a microstructured surface.
