  • Light diffusing articles and methods to manufacture thereof
    Patent number: 6773787
    Abstract: Disclosed herein is a light diffusing substrate in the form of film or sheet including multi-wall sheet and a process for making such light diffusing article, wherein the article comprises a light transmitting thermoplastic resin and about 0.001 to 10 wt. parts of a polyalkyl silsesquioxane, wherein the alkyl group is selected from a methyl, a C12-C18 alkyl, hydride, phenyl, vinyl, and cyclohexyl. The light diffusing substrate is characterized as having a surface roughness expressed as a centerline average height Ra of about or less than 0.1 &mgr;m, a ten-point surface roughness Rz of about or less than 1.0 &mgr;m, and a maximum height surface roughness Rmax of about or less than 1.0 &mgr;m.
