the monomer composition comprising a compound represented by the following Formula (1):

OG Complex Work Unit Chemistry
wherein, in Formula (1):
X represents an n-valent organic group having from 1 to 200 carbon atoms and containing at least one selected from the group consisting of an oxygen atom and a nitrogen atom, wherein the at least one selected from the group consisting of an oxygen atom and a nitrogen atom is bound to Y;
each Y represents a (meth)acryloyl group-containing group (Y1) represented by the following Formula (A), a (meth)acryloyl group (Y2), a hydrogen atom, or a hydrocarbon group having from 1 to 20 carbon atoms, with the proviso that at least one or more Y, among all Ys included in the compound represented by Formula (1), is the (meth)acryloyl group-containing group (Y1);
a plurality of Ys may be the same as or different from each other; and
n represents an integer of 3 or more

OG Complex Work Unit Chemistry
wherein, in Formula (A), R1a represents a hydrogen atom or a methyl group; and R1b represents a divalent organic group having from 2 to 6 carbon atoms, which may be substituted with an alkyl group having from 1 to 6 carbon atoms or a (meth)acryloyloxyalkylene group,
wherein X is any one of groups represented by the following Formulae (X1) to (X10):
