Title: Production of optical organic recording medium
Inventor: SANTO TAKESHI
IPC: B41M5/26
Filed: 1986-10-23
Abstract: PURPOSE:To prevent liquid sagging and creeping of a coating liquid to a central hole by executing continuously a stage for providing a water- and oil-repellent resin layer to the non-recording part on a substrate, then a stage for providing an org. recording layer to the recording part by dip coating of the coating liquid on the substrate. CONSTITUTION:The stage for providing the water- and oil-repellent resin layer 4 to the non-recording part on the substrate and the stage for providing the org. recording layer to the recording part by dip coating of the coating liquid on the substrate are continuously executed. The resin layer 4 functions to prevent the wetting of the part provided with the resin layer 4 with the coating liquid by repelling the coating liquid at the time of providing the org. recording layer by dip coating. The accumulation of the coating liquid in the upper part of the end face in the outer peripheral part of the substrate and in the lower part at the end of the inner peripheral part and the consequent generation of the liquid sagging are, therefore, prevented, by providing the resin layer 4 to the non-recording part on the substrate and dipping the substrate in the coating liquid for the org. recording layer, then pulling up the substrate. The provision of the org. recording layer to the recording part 6 except the non- recording part is thus permitted.
