    • The surface of a metal base is electroplated by utilizing an induction codeposition phenomenon using at least one of carbon dioxide and inert gas, an electroplating liquid containing a metal powder dispersed therein, and a surfactant in a supercritical state or a subcritical state. The concentration of the metal in the electroplating liquid is in a saturated or supersaturated state. Accordingly, the dissolution speed of the metal base can be suppressed, and, at the same time, a plating layer having a smooth surface can be formed in a short time by utilizing an induction codeposition phenomenon. The electroplating method can be applied even when the metal base is formed of a metallic thin film provided on a surface of an insulating film provided on the substrate, or even when the metal is copper, zinc, iron, nickel, or cobalt. The above constitution can provide an electroplating method which, in electroplating on the surface of a metal base, can prevent the dissolution of the metal base to realize normal electroplating even in the case of a very thin metal base.
    • 使用二氧化碳和惰性气体中的至少一种,含有分散在其中的金属粉末的电镀液体和超临界状态或亚临界状态的表面活性剂,利用感应共沉淀现象对金属基体的表面进行电镀。 电镀液中金属的浓度处于饱和或过饱和状态。 因此,可以抑制金属基体的溶解速度,并且同时可以通过利用感应共沉积现象在短时间内形成具有光滑表面的镀层。 即使当金属基底由设置在基板上的绝缘膜的表面上设置的金属薄膜形成时,或甚至当金属为铜,锌,铁,镍或钴时,也可以应用电镀方法。 上述结构可以提供一种电镀方法,即使在非常薄的金属基底的情况下,在金属基体表面的电镀中也能够防止金属基体的溶解,从而实现正常的电镀。

    • There are provided a light polarizing film of a grid type, usable for light at a wavelength in a range of a visible light region to an infrared region, and a method of continuously fabricating the same. A PET film 12 was fed via rolls 13, and a mixed liquid containing poly (vinyl alcohol), formaldehyde, ZnO whiskers after metal treatment, and water was applied to the surface of the PET film to a predetermined thickness with the use of a T-die 14, subsequently executing coating while applying shearing stress by varying peripheral velocity of an upper roll 16 of biaxial rolls from that of a lower roll 16′ thereof, whereupon the ZnO whiskers were oriented in the longitudinal direction of the film. Thereafter, the film was dried and cured through a constant temperature cell 17 kept at a predetermined temperature, and rolls 18 to be subsequently taken up by a take-up roll 19. The light polarizing film obtained was found very high in polarized light reflection property in an infrared region of a wavelength in a range of 1 to 10 μm, and upon measurement of reflectance for two sheets of the light polarizing films crossed at right angles, infrared light reflectance thereof was found at 99%.

    • There are provided a light polarizing film of a grid type, usable for light at a wavelength in a range of a visible light region to an infrared region, a method of continuously fabricating the same, and a reflective optical film using the light polarizing film. A polypropylene film is passed through rolls 12, a first constant temperature cell 13, and rolls 12′ to thereby undergo uniaxial drawing by 4-fold. Thereafter, an aluminum metal is vapor-deposited to a thickness of 100 nm in a vacuum deposition cell 14 to be subsequently passed through rolls 15, a second constant temperature cell 16, and rolls 15′, undergoing uniaxial drawing by 2-fold again while partially crystallizing the polypropylene film. At this point in time, the aluminum metal undergoes substantially uniform cracking in a direction orthogonal to a drawing direction. Thereafter, heat treatment is applied to the film in a third constant temperature cell 17, and the film is subsequently taken out by take-up rolls 18. The film-like light polarizing film obtained had a degree of polarization at 99.5%, and light transmittance at 90%, in a region of infrared wavelength in a range of 1 to 10 μm. With two sheets of the films crossed at right angles, reflectance thereof for infrared rays was measured and was found at not less than 99.9%.
