In one embodiment, the process for forming a multilayer film comprises disposing a supportive layer adjacent to an imprinting layer to form a multilayer film and imprinting microstructures in the imprinting layer as the multilayer film passes between a heated roller and a compression roller. The multilayer film is free of a removable carrier layer. The supportive layer has a supportive layer glass transition temperature that is greater than or equal to about 15° C. higher than the imprinting layer glass transition temperature and/or the supportive layer has a supportive layer melting temperature that is greater than or equal to about 15° C. higher than an imprinting layer melting temperature. The imprinting temperature is lower than the supportive layer melting temperature.

In one embodiment, a brightness enhancement film comprises: a diffusing film comprising a front surface and a back surface, a coating on the front surface, and light redirecting structures disposed in the coating. The brightness enhancement film is capable of collimating light, and wherein, without the coating, the diffusing film would be capable of spread light passing through the back surface. In another embodiment, the brightness enhancement film comprises: a diffusing film comprising a front surface and a back surface, a coating on the front surface, and light redirecting structures disposed in the coating. The diffusing film has a stress retardation gradient of less than or equal to 50 nm/in, wherein an interval for calculation of the stress retardation gradient is less than 1 inch. The brightness enhancement film is capable of collimating light.

A method of inspecting a light-management film comprises reflecting light from an overhead light source off a first side of the light-management film and examining the light-management film for defects; directing transmission light from a backlight source through a second side of the light-management film to the first side and examining the light-management film for defects; reflecting light from the overhead light source off the second side of the light-management film and examining the light-management film for defects; directing transmission light from the backlight source through the first side of the light-management film to the second side and examining the light-management film for defects; and measuring a location of each of the examined defects in the light-management film.

A light management film includes a first layer with a thermoplastic resin and a particular phosphonium sulfonate salt, and a second layer formed from a curable composition and having a refractive index of at least 1.5. The light management film exhibits reduced static electricity build-up and reduced dust attraction, making it easier to handle during fabrication of display devices such as the flat panel displays of laptop computers.

Disclosed herein are copolyester embossed film and methods of making the same. In one embodiment, the film making process comprises forming a substrate film, wherein the substrate film comprises a copolyester stilbene polymer, embossing the substrate film to form an embossed film, and cross-linking the embossed film. In another embodiment, the process comprises forming a substrate film, embossing the substrate film to form an embossed film, and cross-linking the embossed film. The substrate film comprises a copolyester comprising repeating units derived from stilbene dicarboxylic acid, 1,4 cyclohexane dicarboxylic acid, and 1,4-cyclohexane dimethanol.
