摘要： A composite substrate plate for a magnetic or optical disk, comprising a metal plate, an undercoat resin layer formed on one side or both sides of said metal plate, and a surface resin layer having a mirrorlike surface formed on said undercoat resin layer. Such a composite substrate plate is obtained by placing a liquid resin for forming the surface resin layer on the undercoat resin layer formed on one side or both sides of said metal plate or, alternatively, on one or two mirror-finished surfaces of molding plates for imparting a mirrorlike surface to said surface resin layer, then assembling the metal plate and the one or two molding plates so that one side or both sides of said metal plate carrying the undercoat resin layer and the liquid resin may be brought into contact with the one or two clean mirrorlike surfaces of molding plates or, alternatively, one side or both sides of said metal plate carrying the undercoat resin layer and no liquid resin may be brought into contact with the one or two liquid resin-bearing surfaces of molding plates, subsequently allowing the liquid resin to cure, and removing the one or two mirror-finished molding plates.

摘要： An optical recording medium comprising a transparent substrate of a synthetic resin and an information recording layer provided thereon, on which medium information can be optically written, read and erased by means of a laser light, wherein said transparent substrate consists essentially of a cast-cured product of an epoxy resin composition comprising an alicyclic epoxy resin, or a mixture of a major amount of an alicyclic epoxy resin and a minor amount of an aromatic epoxy resin, an organic polybasic acid anhydride, a curing-accelerator and an anti-discoloring agent.
