PURPOSE: To reduce the contraction for hardening and to improve the transfer precision and the flatness, by using a radiation hardening lacquer which consists of only a monomer capable of open ring polymerization or contains this monomer partially.
CONSTITUTION: A lacquer layer 2 which is hardened by radiation is provided on a mold for transfer such as a negative plate or a stamper, and a plastic substrate or a glass substrate 3 is placed on the lacquer layer 2 to hold the lacquer layer 2 between the mold 1 for transfer and the substrate 3, and in this state, the substrate 3 is irradiated with radiation 5 to harden the lacquer layer 2. The lacquer layer 2 consists of a monomer capable of open ring polymerization, for example, a compound capable of cation polymerization such as a cyclic ester, a cyclic formal, or the like or a compound capable of radical polymerization such as a vinyl cyclopropane derivative, a cyclic acetal having unsaturated bonding, an ether, or the like.
