Title: Formation of light controlling film
Inventor: KUME MAKOTO
IPC: G02B5/00
Filed: 1988-08-30
Abstract: PURPOSE:To prepare a light controlling film simply by fixing inorganic colored particles scattered onto a transparent plate coated with an adhesive in the presence of a magnetic field wherein a major axis direction of the particles is oriented toward a perpendicular direction to the plate. CONSTITUTION:Magnetic particles having acicular, fibrous, or flake shape are oriented on a transparent flat plate so that the major axis direction of the particles is arranged to an almost perpendicular direction of the flat plate by a magnetic field, and the particles are fixed on the surface of the flat plate with a transparent tacky adhesive coated on the flat plate. If the magnetic field is absent, the particles tend to be arranged toward a direction coinciding with a face direction of the flat plate, resulting no light controlling effect. Since the light incident into the flat plate from a perpendicular direction intersects scarcely the colored, particles, the light is transmitted, causing thereby hardly absorption. On the other hand, if the light is incident obliquely, the intersecting ratio of the light across the colored particles increases in accompany with the increase of an angle of incidence, so more quantity of light is absorbed causing a decrease of the amt. of transmitted light. Thus, the prepn. of the light controlling film is simplified, and the film is prepd. inexpensively with uniform quality of the film.
