Abstract: The invention relates to a polymeric optical film comprising a base provided with integral optical features on at least one side, wherein the features have two or more sides that form a ridge line, wherein the optical film has light leakage through crossed polarizers of less than 1.0%.

Abstract: An inkjet recording element comprising a support coated with an immiscible polymer blend to overcome limitations of existing hydrophilic materials for extrusion coating. The two phases correspond, respectively to a first composition comprising a hydrophobic thermoplastic polymer such as a polyolefin, which does not absorb water, and a second composition comprising a hydrophilic thermoplastic polymer, for example, polyvinyl alcohol, modified ethyl vinyl alcohol, polyether block polyamide, or the like. The characteristics of the polymers are such that hydrophilic thermoplastic polymer encapsulates the polyethylene layer during extrusion and produces a swellable inkjet receiver layer. Also disclosed are methods for making and a method of printing on such inkjet recording elements.
