A composition including a compound (A) represented by general formula (I), and a compound (other than the compound (A)) having two or more polymerizable functional groups in the molecule thereof, the mass ratio ((A)/(B)) of the compound (A) and the compound having two or more polymerizable functional groups in the molecule thereof being 30/70 to 50/50. [In general formula (I): R 1 and R 2 each independently represent any group selected from the group consisting of a hydrogen atom, a C1-6 alkyl group, and a C2-6 alkenyl group, aryl group, or aralkyl group; R 3 represents any group selected from the group consisting of a C1-6 alkyl group, and a C2-6 alkenyl group, aryl group, or aralkyl group; R 4 represents any group selected from the group consisting of a (meth)acryloyl group, a styryl group, and a C2-6 alkenyl group; and n represents any integer of 1-5.] |
