摘要： An optical recording medium is prepared by the use of spiropyrane whose molecular structure contains an alkyl chain having at least 10 more carbon atoms, and by the use of an LB film method or a spin coating method. This recording medium is of a structure wherein when irradiated with the UV, the spiropyrane is photo-isomerized to photomerocyane and, thereafter, when subsequently heated at 35 to 40°C for 15 minutes, a J-aggregate of the photomerocyane is formed in very stabilized form. When the recording medium is irradiated with light of wavelength of visible spectrum, the color is bleached with the information consequently recorded. The optical recording medium herein disclosed is rewritable and can retain the recorded information for 5,000 hours or more.

摘要： Provided is an information recording medium, e.g., an optical recording medium, and a method for recording information thereon. The information layer of the recording medium comprises an organo macrocyclic chromophore containing a central hetero atom or two central hydrogen atoms or isotopes of hydrogen, e.g., a naphthalocyanine having silicon as the hetero atom, which chromophore is substituted with at least one substituent conferring film forming properties to the chromophore, e.g., a monomer or oligomeric substituent comprised of acid, amide or ester units. The information layer thereby offers excellent thermomechanical properties and exhibits excellent absorption properties all in a single component material. By utilizing a single component material, the problem of dye/polymer phase separation frequently encountered in dye/polymer mixtures is also overcome.

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.
