Title:
ULTRAVIOLET LIGHT CURING URETHANE ACRYLATE COMPOSITION, THIN-FILM FORMED BODY, OPTICAL FILM, AND METHOD FOR MANUFACTURING THIN-FILM FORMED BODY
Document Type and Number:
WIPO Patent Application WO/2013/146193
Kind Code:
A1
Abstract:
Provided is an ultraviolet light curing urethane acrylate composition with excellent ultraviolet light curing properties without containing a photo polymerization initiator, and that can be used for optical applications that require high transparency. The present invention is an ultraviolet light curing urethane acrylate composition containing (E) a urethane acrylate oligomer having a (meth)acryloyl group on the terminal of a molecule obtained by addition reaction of (D) a (meth)acrylate compound having a hydroxide group to (C) a urethane polymer having an isocyanate group on the terminal of a molecule obtained by reacting (A) a polyol that does not have an aromatic backbone and (B) a polyisocyanate that does not have an aromatic backbone; wherein the composition further contains 0.2 to 80 mass% of (F) at least one type of organic solvent that does not have an aromatic backbone, selected from the group consisting of ketone solvents, amide solvents, and alkyl halide solvents; and wherein the composition does not contain a photo polymerization initiator.
