An optical recording medium is provided with: a light transmissive substrate; a recording film formed of an organic dye with 2,2,3,3-tetrafluoro-1-propanol having pH of not less than 6.0 as a solvent, on a surface of the substrate; a reflective film formed on a surface of the recording film; and a protection film formed on a surface of the reflective film.
摘要:
A planar display device having a fast display reaction time and which can have a large screen size but which is thin and light in weight. A face plate is provided which contains fluorescent materials sensitive to three different wavelengths of invisible ultraviolet rays and which emit light in red, green and blue colors in response to stimulation by rays of the three wavelengths. The three fluorescent materials may be stacked together in layers or mixed in a single layer with a binder, and a wavelength-converting layer may be employed.
摘要:
A reflectance of an optical recording medium provided with a light transmission substrate on which a recording film containing a dye material is formed is controlled or regulated by providing a recording film which is formed by a method comprising the steps of preparing a solution containing only a non-aggregated portion of a dye material and a solution containing only an aggregated portion of a dye material, mixing both the solutions with a predetermined mixing ratio to prepare a mixture solution and coating the mixture solution on a surface of a light transmission substrate to form a recording film of an optical recording medium having a predetermined reflectance by changing the mixing ratio. The aggregated portion of the dye material is a metal phthalocyanine aggregated material represented.
摘要:
An optical recording medium has a substrate and a recording film provided on the substrate. The recording film contains organic coloring matter and polyvinylbutyral. The organic coloring matter and polyvinylbutyral are dissolved by a solvent and coated on the substrate to form the recording film.
