Abstract:
The present invention provides a thermal transfer sheet comprising a substrate, and a light-to-heat conversion layer containing a substance capable of converting light to heat and a binder, and an image forming layer, which are disposed on the substrate, wherein the binder in the light-to-heat conversion layer is a polyimide resin soluble in an organic solvent. In the thermal transfer sheet provided by the present invention, the light-to-heat conversion layer is not affected by the coating liquid disposed as a layer on the light-to-heat conversion layer. Further, the light-to-heat conversion layer thus formed exhibits high heat resistance and humidity resistance. Accordingly, the thermal transfer sheet of the present invention produces good images with little or no fogging.
Abstract:
An optical information recording medium of two disc substrates, which are adhered directly or through a convex portion formed on at least one of the substrates or a spacer provided between the substrates by an adhesive layer, and a recording layer which is capable of recording and/or reading information by laser beam and which is provided on a surface of at least one of the substrates facing the other substrate, wherein the adhesive layer is formed by an ultraviolet-curing epoxy adhesive composition comprising a light-initiator which produces a cationic polymerization initiator upon irradiation with ultraviolet rays and an epoxy compound having two or more epoxy groups per molecule.
Abstract:
In a method for recording information by irradiating an optical information recording material comprising a heat mode recording layer comprising a metal on a base with a light beam, the method for recording optical information in which said heat mode recording layer consists of a metal and at least one metal compound selected from metal oxides and metal sulfides and the proportion of the amount of the metal to that of said metal compound increases or decreases in the direction of the thickness of the layer, said recording layer having a layer comprising of mixture of at least one of the metal and at least one of the metal compound, in which irradiation with the light beam is conducted from the side where the proportion of the metal in the recording layer is smaller, and in which melting and removing are conducted until the difference in reflectance of the light between the non-recorded area and the recorded area reaches an extent which permits reading by light. The method permits highly sensitive recording by a light beam of a lower energy and can afford a record of information suitable for reflex reading.
Abstract:
A light information recording medium is disclosed. The medium is comprised of a support which has transparency with respect to light. The support has coated thereon a light sensitive recording layer which contains SiO.sub.2 and In at the SiO.sub.2 content of 10 to 35 vol. % based on the total volume of SiO.sub.2 and In. The recording medium can be used for the recording and reading of the information recorded thereon by striking the medium with laser light from the support side. The recording medium can be used as an optical disk memory having excellent recording sensitivity with respect to laser light, long preservability and high resolving power as well and high S/N ratio.
Abstract:
