| abstract |
a compound (A) represented by the following general formula (I), and a compound (B) having two or more polymerizable functional groups in the molecule (with the exception of compound (A)); The composition in which the mass ratio ((A)/(B)) of the compound (B) which has two or more polymerizable functional groups in a molecule|numerator is 30/70-50/50. [In general formula (I), R 1 and R 2 each independently represent any one selected from the group consisting of a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an aryl group, and an aralkyl group , R 3 represents any selected from the group consisting of an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an aryl group and an aralkyl group, and R 4 is a (meth)acryloyl group, a styryl group and a carbon number Any selected from the group consisting of 2-6 alkenyl groups is shown. n represents an arbitrary integer of 1 to 5.] |
