Patent ID: 7419715

Claim:
A light diffusing resin film: wherein the light diffusing resin film is formed by light-curing a light-curable liquid resin composition whose indispensable components are a photo-polymerizable monomer (A), an aliphatic amino alcohol (B) that is incompatible with the photo-polymerizable monomer (A), a cosolvent (C) that is compatible commonly with the photo-polymerizable monomer (A) and the aliphatic amino alcohol (B) that is incompatible with the photo-polymerizable monomer (A), and a photo-polymerization initiator (D); wherein all indispensable components are present during the light-curing; wherein the cured light diffusing resin film is substantially transparent; wherein the aliphatic amino alcohol (B) comprises at least 15 wt % of a combined amount of the indispensable components; wherein the photo-polymerization initiator (D) is selected from group consisting of carbonyl compound based photo-polymerization initiators, organic sulfur compound based photo-polymerization initiators, and organic phosphorus compounds based photo-polymerization initiators in amount ranging from 0.1 to 3.0% by weight with respect to the photo-polymerizable monomer (A); and wherein the light diffusing resin film is an aggregate of fine particles of cured resin having an average particle diameter in the range of 0.1 to 0.9 μm.
