Abstract
A process for producing an optical member comprises forming a resin layer on the surface of a glass substrate by filling with a resin the gap between a master having a releasing layer on the surface and a glass substrate and separating the master to produce an optical member constituted of a glass substrate and a resin layer and the releasing layer is comprised of a compound having a fluorine-substituted hydrocarbon group and an alkoxysilane group or a silane halide group. The releasing layer may be treated with an amine or an acid so as to form a rigid adherence between the compound forming the releasing layer and the surface of the master by chemical bonding. The releasing layer is subjected, if desired, to a thin film-forming treatment. The thin film-forming treatment is carried out, for example, by ultrasonic cleaning.
