INTERLAYER FILM FOR COLORED LAMINATED GLASS, AND COLORED LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2018/025932
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an interlayer film that is for colored laminated glasses, and that has, when being used to produce a laminated glass using two sheets of clear glass conforming to JIS R3202 (1996), a visible-light transmittance Tv of 5% or less, a small variation in visible-light transmittance between portions thereof, and superior aesthetic appearance; and a colored laminated glass using the interlayer film for colored laminated glasses. This interlayer film for colored laminated glasses has a recessed portion on at least one of the surfaces and has, when being used to produce a laminated glass using two sheets of clear glass conforming to JIS R3202 (1996), a visible-light transmittance Tv of 5% or less, wherein the interlayer film comprises a laminate having at least two layers including a first resin layer containing a thermoplastic resin and a coloring agent and a second resin layer containing a thermoplastic resin and not containing a coloring agent, the ratio E1/E2 of the elasticity modulus E1 of the first resin layer to the elasticity modulus E2 of the second resin layer is 1.25 or more, and the ratio t1/t2 of the thickness t1 of the first resin layer to the thickness t2 of the second resin layer is 2.0 or less.
