Title:
ANISOTROPIC OPTICAL FILM COMPOSITION AND ANISOTROPIC OPTICAL FILM
Document Type and Number:
WIPO Patent Application WO/2022/044598
Kind Code:
A1
Abstract:
Provided is an anisotropic optical film composition for producing a light diffusion film that can achieve both excellent diffusibility and hue. The anisotropic optical film composition contains: component (A-1) of a (meth)acrylic ester having at least one fluorene skeleton and at least one (meth)acryloyl group; component (A-2) of a (meth)acrylic ester that has at least one aromatic ring and at least one (meth)acryloyl group and does not have a fluorene skeleton; component (B) of a thermoplastic polymer having a weight average molecular weight of 1,000-500,000 and a glass transition temperature of -40 °C or higher; and component (C) of a photopolymerization initiator, wherein the content of component (A-1) is 3-100 parts by weight with respect to 100 parts by weight of the content of component (A-2), and the content of component (B) is 10-400 parts by weight with respect to 100 parts by weight of the sum of the (meth)acrylic ester containing component (A-1) and component (A-2).
