LIGHT DIFFUSION FILM AND LIGHT SOURCE DEVICES PROVIDED WITH THE FILM

摘要

The invention relates to a light diffusion film made by using a thermosetting resin as the binder resin for a light diffusion layer and aims at attaining desired luminance and clarity, particularly enhanced luminance and suppressed clarity, without impairing the printability and cuttability inherent in the thermosetting resin. The invention relates to a light diffusion film provided with a light diffusion layer containing both a binder resin containing a thermosetting resin as the main component and a light diffusion agent wherein the binder resin contains a liquid or pasty fluorinated additive which does not contain any hydrophilic groups in the molecule. The liquid or pasty fluorinated additive is preferably one having at least one fluoroalkyl group and at least one ether linkage in the molecule, while the additive is contained in an amount of 3 to 16 parts by weight per 100 parts by weight of the binder resin.
