A polymerizable composition is provided which is constituted by adding isocyanate by 0.1 to 2 equivalent to the alcoholic hydroxyl group in a mixture dissolving component A prescribed below by 20 to 60 parts by weight to a total of 80 to 40 parts by weight of component B and component C in the ratio specified below:
[Component A]
A multifunctional (meth)acrylate possessing at least one alcoholic hydroxyl group, and also possessing at least one aromatic ring replaced by at least one halogen atom other than fluorine or phenyl group, and two or more (meth)acryloyl groups in a molecule:
[Component B]
A multifunctional (meth)acrylate possessing at least one aromatic ring having neither halogen atom nor phenyl group as substituent, and posessing two or more (meth)acryloyl groups in a molecule, or a mixture of radically polymerizable multifunctional unsaturated monomer including the compound; 5 to 80 wt.%:
[Component C]
A mixed solution of a styrene type compound, or a radically polymerizable monofunctional unsaturated monomer including the compound; 95 to 20 wt.%.
