<p>A polymerizable compound represented by the general formula (1): (1) wherein A is a ring assembly consisting of at least two six-membered rings, each ring bearing a substituent optionally; X1 and X2 are each (meth)acryloyloxy; Y1 and Y2 are each independently a single bond, optionally branched alkylene having 1 to 8 carbon atoms, an ether linkage,-COO-,-OCO-, a six-membered ring which may have a substituent, a naphthalene ring which may have a substituent, or a combination of two or more of them; and the substituents are each hydrogen, halogeno, cyano, optionally branched alkyl having 1 to 8 carbon atoms, optionally branched alkoxy having 1 to 8 carbon atoms, or optionally branched alkenyl having 2 to 8 carbon atoms, with the provisos that a-CH2-group in the alkyl, the alkoxy or the alkenyl may be replaced by sulfur or oxygen and that a hydrogen atom in the alkyl, the alkoxy or the alkeny may be replaced by halogen or cyano.</p> |
