Abstract
According to the invention, provided are an optical alignment film composition with which an optical alignment film having excellent aligning properties can be produced, and an optical alignment film, an optical laminate, and an image display device produced using the optical alignment film composition. An optical alignment film composition according to the invention contains a polymer A which has a constitutional unit a1 including a cinnamate group and a low-molecular-weight compound B which has a cinnamate group and has a lower molecular weight than the polymer A.
Claims20
An optical alignment film composition comprising:
- a polymer A which has a constitutional unit a1 including a cinnamate group;
- and
- a low-molecular-weight compound B which has a cinnamate group and has a lower molecular weight than the polymer A,
- wherein the low-molecular-weight compound B is a compound represented by Formula (B1),
- here, in Formula (B1), a represents an integer of 0 to 5, R1 represents a chain or cyclic alkyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, or an aryl group having 6 to 20 carbon atoms which may have a substituent, and R2 represents a branched-chain alkyl group having 1 to 20 carbon atoms, and in a case where a is 2 or greater, a plurality of R1's may be the same as or different from each other.
