The present invention provides a laminated glass for vehicles exerting the functions that are difficult to be made compatible in combinations such as (1) a shade band in an interlayer and an optical device such as a CCD camera, (2) a heat shielding interlayer and an optical device, and (3) a heat shielding interlayer and a combiner. In this laminated glass for vehicles, the interlayer includes a first region and a second region that is either enclosed by the first region or formed by partially recessing an edge portion of the first region. The first region is provided with a light reducing function that imparts a light transmittance loss at least of visible light, and in the second region, the interlayer has a light transmittance loss of visible light that is smaller than that in the first region.

Laminated glass for vehicles and method for manufacturing the same

The present invention provides a heat-reflecting windshield that includes a laminated glass sheet and a detecting device for optically detecting a target object such as water droplets. The laminated glass sheet includes a first glass sheet, a heat-reflecting film formed on the first glass sheet, an intermediate film and a second glass sheet. The detecting device is disposed on a main surface of the laminated glass such that a light-emitting element and a light-receiving element in the device are arranged in a predetermined region of the main surface, and the predetermined region is rubbed by a windshield wiper. The heat-reflecting film includes at least three dielectric layers and at least two metal layers, and the heat-reflecting film is not formed in said predetermined region.

The present invention provides a laminated glass sheet for windshield that includes a transparent conductive film and enables ITS communication. The laminated glass sheet includes a first bus-bar aranged along an upper end of the laminated glass sheet, and a second bus-bar arranged along a lower end of the laminated glass sheet, and the first busbar includes a protruding portion that extends toward the second bus-bar, and the transparent conductive film is not formed in a concave portion that is formed by the protruding portion. Since the concave portion can be used for the communication, the conductive film may be free from an opening.

The present invention is directed to a light-transmitting color film comprising oxides which have high chemical resistance and excellent light-absorption effect, making them available in a wide color range; a method for producing the same; and a coating solution used for forming the color film. In the light-transmitting color film comprising an oxide of an element which serves as a network former and oxides of transition metal elements serving as coloring components, the element serving as a network former is at least one selected from Si, Al, and B, and the transition metal elements comprise Cu, Mn, and Ni; and the two types of oxides form a complex oxide. Moreover, a method for producing the light-transmitting color film comprises: coating on the substrate a coating solution for forming the color film which contains at least one alkoxide of elements selected from Si, Al, and B which serve as network formers, and as coloring components, transition metal salts comprising at least Cu, Mn, and Ni, and at least one organic compound having a functional group which can coordinate the transition metals; and thereafter firing the substrate.

Light-transmitting color film, method for producing the same, and coating solution for forming the color film

There is provided a method of manufacturing a glass plate with a light-transmissive colored film using a coating solution including a metal salt and a metal alkoxide, the light-transmissive colored film having a coloring effect due to a metal oxide which will not be impaired even if the amount of the added metal alkoxide is increased, and being highly resistant to wear and chemicals. A method of manufacturing a glass plate with a light-transmissive colored film comprises the steps of hydrolyzing and polymerizing a metal alkoxide to form a hydrolyzed polymeric product, aging the hydrolyzed polymeric product to achieve a weight-average molecular weight no less than 3000 based on polystyrene, preparing a coating solution including the hydrolyzed polymeric product, a metal salt as a coloring component, and a solvent, coating the coating solution on a surface of a glass plate, preliminarily firing the glass plate to convert the hydrolyzed polymeric product into a porous gel, and firing the glass plate to vitrify the porous gel and thermally decompose the metal salt into an oxide.
