Document Type and Number:
WIPO Patent Application WO/2022/255393
Kind Code:
A1
Abstract:
A resin film according to the present invention is configured such that if one surface of a laminated glass, which is obtained by bonding two reference glass sheets having a thickness of 2.5 mm to each other, with the resin film being interposed therebetween, is irradiated with simulated sunlight by means of a solar simulator from a direction that is perpendicular to the surface, the ratio of the minimum value to the maximum value among the luminances measured from directions at angles of 30°, 45°, 60° and 75° with respect to the direction that is perpendicular to the other surface of the laminated glass is 0.1 or more. A laminated glass according to the present invention comprises a resin film according to the present invention and a pair of glass members; and the resin film is arranged between the pair of glass members. A screen according to the present invention is configured such that if one surface of this screen is irradiated with simulated sunlight by means of a solar simulator from a direction that is perpendicular to the surface, the ratio of the minimum value to the maximum value among the luminances measured from directions at angles of 30°, 45°, 60° and 75° with respect to the direction that is perpendicular to the other surface is 0.1 or more. The present invention is able to provide: a resin film which enables the achievement of image display with high contrast, while lowering the haze of a laminated glass; a laminated glass; and a screen.
