ABSTRACT:
Disclosed herein is a method for transferring a pattern of minute dents and projections to an energy ray-setting resin layer coated on a substrate plate by pressing a master pattern on a transfer mold, followed by irradiation of energy rays. The pattern transfer method comprises the steps of pressing a master pattern on a transfer mold against the resin layer under a predetermined imprinting pressure, irradiating the resin layer under the imprinting pressure with energy rays, interrupting the irradiation of energy rays and at the same time cancelling application of the imprinting pressure and holding the resin layer and the transfer mold in a non-pressed state to relieve the resin layer of internal stresses, and recommencing irradiation of the resin layer with energy rays to complete hardening of the resin layer which is held in contact with the transfer mold in a non-pressed state.
