摘要： The invention relates to a transparent coating on a transparent glass pane which may be a laminated glass pane such as an automobile windshield. The present invention provides a two-layer coating including a first layer which is a transparent oxide film in direct contact with the major surface of the glass substrate and a second layer which is a transparent oxide film. The first layer has a thickness of 70-230 nm and a refractive index of 1.80-2.10 and includes a major portion and a minor portion which is exposed and adapted to be used as a combiner of a head-up display system. The second layer is formed on the major portion of the first layer so as to expose the minor portion of the first layer. The second layer has a thickness of 110-130 nm and a refractive index of 1.40-1.50. An additional film is optionally formed on the minor portion of the first layer so as to fully or partly cover the minor portion. The additional layer is adapted to be used as a wavelength-selective combiner of the head-up display system. The two-layer coating except the minor portion is adapted to be used as a reflectance reducing coating. To reduce the reflectance of perpendicularly incident light the two-layer coating can be modified into a three-layer coating by interposing another oxide film.

摘要： The present invention relates to a head-up display system which includes an element thereof. The element is attached to, for example, an automobile windshield so as to project light rays carrying images of display information onto the element from a luminous source in a car. The element includes first and second reflection layers. The first layer is directly attached to the windshield and has a relatively uniform reflectance throughout visible light spectrum. The second layer is directly formed on the first layer and has a selective reflection against incident visible light of wavelengths in the range from about 500 nm to about 600 nm. Thus, the light rays from the luminous source are displayed on the first and second layers in different colors.

摘要： The invention relates to a sol-gel method for forming a metal oxide film, e.g. TiO.sub.2 film or TiO.sub.2 -SiO.sub.2 film, on a substrate by applying a solution of at least one metal alkoxide to the substrate to form a sol film on the substrate, drying the sol film to cause it to turn into a gel film by hydrolysis and baking the gel film. According to the invention the viscosity of the metal alkoxide solution is adequately increased, preferably to 3-30 cP at 20.degree. C., by the addition of a combination of a hydroxypropyl cellulose of which 2 wt % aqueous solution has a viscosity of 150-400 cP at 20.degree. C. and another hydroxypropyl cellulose of which 2 wt % aqueous solution has a viscosity of 6-10 cP at 20.degree. C. Metal oxide films formed by this method are free from minute cracks and excellent in optical characteristics and durability. By this method it is possible to form a metal oxide film as thick as about 300 nm without repeating the application of the alkoxide solution to the substrate.

The invention provides a reflectance-reducing glass pane including: a transparent glass substrate having first and second major surfaces opposed to each other; a first reflectance-reducing coating formed on the first major surface of the glass substrate; and a second reflectance-reducing coating formed on the second major surface of the glass substrate. The first coating has at least two metal-oxide layers which are different in refractive index. The second coating has a refractive index of up to 1.50 and is made of one selected from the group consisting of SiO.sub.2 and a mixture of SiO.sub.2 and another metal oxide. The reflectance-reducing glass pane optionally further includes a third water-repellent coating which is formed on the second coating. The third coating comprises a silane compound containing a polyfluoroalkyl group. The reflectance of the glass pane is substantially low, with respect to a visible light incident on the glass pane from a side of the first coating at an incidence angle within a range from 40 to 80 degrees.

摘要： The invention relates to a transparent coating on a transparent glass pane which may be a laminated glass pane such as an automobile windshield. The invention provides a two-layer coating made up of a first oxide film, e.g. a TiO.sub.2 -SiO.sub.2 mixed oxide film, which is in contact with the glass pane and has a thickness of 70-100 nm and a refractive index of 1.80-1.90 and an outer second oxide film, e.g. a SiO.sub.2 film, which has a thickness of 110-130 nm and a refractive index of 1.40-1.50. With respect to visible light obliquely incident on the coating side of the glass pane at an angle of 50-70 degrees with the normal, the reflectance of the coated glass pane becomes lower than that of the glass pane without coating by 4.5-6.5%. To reduce the reflectance of perpendicularly incident light the two-layer coating can be modified into a three-layer coating by interposing another oxide film, e.g. a TiO.sub.2 film, having a thickness of 130-160 nm and a refractive index of 2.05-2.30 between the above described first and second oxide films. The three-layer coating is nearly equivalent to the two-layer coating in the ability to reduce the reflectance of obliquely incident light.
