Vehicle-windshield-glass intermediate film, rolled body, and vehicle windshield glass

摘要

The purpose of the present invention is to provide: a vehicle-windshield-glass intermediate film which makes it possible to produce a vehicle windshield glass with high yield by using a vacuum degassing method, and which has concavities formed in a ruled-line pattern; a rolled body of said vehicle-windshield-glass intermediate film; and a vehicle windshield glass which uses said vehicle-windshield-glass intermediate film. The present invention pertains to a vehicle-windshield-glass intermediate film having a plurality of concavities and a plurality of convexities on one or more surfaces thereof, wherein: the floor sections of the concavities have a continuous groove shape; adjacent concavities are regularly arranged in parallel with one another; and furthermore, the slope of the groove-shaped concavities having continuous floor sections is 35° or more relative to the direction of flow of the film when producing the vehicle-windshield-glass intermediate film.
