摘要:
The present invention provides a method for producing an optical recording medium having: a supporting substrate; a light transmission layer, which transmits a laser beam; and an information layer formed between the supporting substrate and the light transmission layer, which includes: applying a resin composition on the information layer by a spin coating method to form a coating film, wherein the resin composition contains, as main components: (A) a radical-curing urethane(meth)acrylate, which is obtained by reacting (a-1) a compound having three or more isocyanate groups binding to an aliphatic carbon atom per one molecule thereof and (a-2) a polycaprolacton-modified hydroxyethyl(meth)acrylate; and (B) a radical-curing monomer having a viscosity of 400 mPa.s or less at 25° C., curing the coating film by irradiating the coating film with an ultraviolet light or an electron beam to form the light transmission layer.

摘要:
A recording method whereby an inorganic resist made of an incomplete oxide of a transition metal is formed as a film onto a substrate and a latent image corresponding to pits is formed onto the inorganic resist by exposure. The exposure is performed by a laser beam whose intensity has been modulated by a pulse signal whose pulse height decreases in a rear portion in a length direction of the pit, thereby forming a format of a track pitch smaller than a recording beam diameter(track pitch/exposure beam diameter=0.333 to 0.833).
摘要:
In the production of a nuclear-hydrogenated polymer, the hydrogenation of an aromatic vinyl compound—(meth)acrylate copolymer is conducted in a mixed solvent comprising an ester compound and an alcohol compound in the presence of a catalyst. By this method, a highly transparent nuclear-hydrogenated polymer is produced safely, stably and quickly, even when the degree of nuclear-hydrogenation is low.
