ABSTRACT:
The UV crosslinking compound of the present invention is characterized in having the following chemical formula, and has high photosensitivity. Accordingly, the crosslinking reaction can be accomplished within a short period of time. Thus, if this compound is employed in the alignment film for a LCD component, it becomes possible to carry out a sufficient alignment treatment with UV irradiation over a short period of time. Accordingly, production time can be shortened and production costs reduced. ##STR1## wherein, n is an integer, and X is an atom selected from among F, Cl, Br, I and CN.
