Process for producing a resin molded article having a patterned surface, a method of manufacturing a stamper master, and the resin molded article of the manufacturing equipment

摘要

PURPOSE: To provide the method for forming a resin molding having rugged patterns on a surface formed with a photosetting resin,(abbreviated as 2P) replica to prevent the shrinkage on curing of the 2P without intrusion of bubbles and bleeding out of the 2p. ;CONSTITUTION: An original mold 1 having the rugged patterns 1' and a glass substrate 2 are disposed to face each other to form a cell 4 having a gap via a spacer material 3 in the outer peripheral edge. The internal pressure of the cell 4 is set smaller than the external pressure to inject the 2P into the cell 4 from an injection port 5 by the differential pressure between the external pressure and the internal pressure. The original mold and the substrate are peeled after the 2P is cured, by this treatment the resin molding having the rugged patterns on the surface formed with the replica of the original mold is formed.;COPYRIGHT: (C)1993,JPO&Japio
