Abstract:
1. 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 with energy rays, characterized in that said method comprises the steps of: pressing said transfer mold against said resin layer by application of a predetermined imprinting pressure in a pattern imprinting stage to imprint profiles of minute dents and projections of said master pattern on said resin layer; hardening said resin layer in a first hardening stage, irradiating energy rays toward said resin layer which is still in pressed contact with said transfer mold under said imprinting pressure; temporarily interrupting irradiation of energy rays of hardening of said resin layer halfway in an interrupting stress relieving stage, holding said transfer mold in a non-pressed state to relieve internal stresses of said resin layer; and recommencing irradiation of energy rays to complete hardening of said resin layer in a second hardening stage, holding said transfer mold in contact with said resin layer in a non-pressed state.
