Synthetic example 1

[0189]2.5 g of MAA, 9.2 g of MMA, 5.0 g of HEMA, and 0.2 g of AIBN as a polymerization catalyst were dissolved in 50.7 g of PM, and reacted at 70° C. for 20 hours to obtain an acrylic copolymer solution (solid content concentration: 25% by mass) (P1). Mn of the obtained acrylic copolymer was 19,600, and Mw was 45,200.

Synthetic example 2

[0191] 25.0 g of BMAA and 1.04 g of AIBN as a polymerization catalyst were dissolved in PM 48.4 g, and reacted at 85° C. for 20 hours to obtain an acrylic copolymer solution (solid content concentration: 35% by mass) (P2). Mn of the obtained acrylic copolymer was 4800, and Mw was 3100.

Abstract

An aim of the invention is to provide a cured-film formation composition for forming a cured film having photoreaction efficiency and solvent resistance, and high adhesiveness alignment uniformity, and an orientation material for photo-alignment, and a retardation material formed by use of the orientation material. A cured-film formation composition includes (A) a compound having a photo-aligning group and one substituent selected from a hydroxy group, a carboxy group, and an amino group; (B) a hydrophilic polymer having one or more substituents selected from a hydroxy group, a carboxy group, and an amino group; and (C) a polymer obtained by polymerizing a monomer including an N-hydroxymethyl compound or an N-alkoxymethyl (meth)acrylamide compound, and optionally further a cross-linking catalyst as a component (D). By use of the composition, a cured-film is formed and an orientation material is formed by utilizing photo-alignment technique. A retardation material is obtained by applying a polymerizable liquid crystal on the orientation material and curing it.

Description

[0001] The invention of this application is a divisional application of the application No. 201380037032.2, the title of the invention is "Cured Film Forming Composition, Orientation Material and Phase Difference Material", and the filing date is July 11, 2013. technical field [0002] The present invention relates to a composition for forming a cured film, an orientation material, and a retardation material. Background technique [0003] In recent years, in the field of displays such as televisions using liquid crystal panels, development of 3D displays capable of viewing 3D images has been progressing as an effort to increase performance. In a 3D display, for example, an image having a three-dimensional effect can be displayed by allowing the viewer's right eye to view a right-eye image and the viewer's left eye to view a left-eye image. [0004] There are various systems for a 3D display displaying a 3D image, and a lenticular lens system, a parallax barrier system, and t...
