    • 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%.

    • This invention provides an electroless plating method comprising electrolessly plating the surface of a metal base sample using a supercritical fluid or a subcritical fluid in such a state that a metal powder is dispersed in an electroless plating liquid. According to this method, a homogeneous and thick plating layer is formed in a short time by taking advantage of an induction eutectoid phenomenon. In the electroless plating method, the metal powder may have an average particle diameter of not less than 1 nm and not more than 100 &mgr;m, and the electroless plating method may also be applied to a damascene process or a dual damascene process which is a method for forming a fine metal wiring within a semiconductor element. The above constitution can provide an electroless plating method which can realize the formation of an even film by electroless plating in a short time using a subcritical fluid or a supercritical fluid by taking advantage of an induction eutectoid phenomenon.

    • 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%.
