Resin film, laminated glass and screen

Abstract

The resin film of the present invention is such that, when one surface of a laminated glass obtained by adhesion of two sheets of standard glass having a thickness of 2.5 mm with the resin film being interposed is irradiated with simulated solar light by a solar simulator in a perpendicular direction, a ratio between a maximum value and a minimum value with respect to brightness measured in directions at angles relative to a direction perpendicular to other surface of the laminated glass, of 30°, 45°, 60° and 75°, is 0.1 or more. The laminated glass of the present invention comprises the resin film of the present invention and paired glass members, in which the resin film is placed between the paired glass members. The screen of the present invention is such that, when one surface is irradiated with simulated solar light by a solar simulator in a perpendicular direction, a ratio between a maximum value and a minimum value with respect to brightness measured in directions at angles relative to a direction perpendicular to other surface, of 30°, 45°, 60° and 75°, is 0.1 or more. According to the present invention, there can be provided a resin film, a laminated glass and a screen, in which high-contrast image display is realized with the laminated glass being low in haze.
