INTERLAYER FOR LAMINATED GLASS AND LAMINATED GLASS

摘要

PROBLEM TO BE SOLVED: To provide a laminated glass in which the loss of transmittance of a ray having a specified wavelength in a partial region is decreased without taking much time and effort of operation, and to provide an interlayer for the laminated glass. SOLUTION: The interlayer for the laminated glass comprises a first interlayer having a region which gives a loss of transmittance of a ray having a specified wavelength when a laminated glass is composed and a second interlayer which gives a loss of transmittance of a ray having a specified wavelength which is less than the loss given by the region of the first interlayer when a laminated glass is composed and has an area of the interlayer surface of a quarter of the first interlayer or less. The second interlayer is superposed on a part of the surface of the region which gives transmittance loss. The thickness of the interlayer in the region on which the second interlayer is superposed is larger than that in region on which the second interlayer is not superposed. COPYRIGHT: (C)2007,JPO&INPIT
