Abstract:
The present invention aims to provide an interlayer film for a colored laminated glass which exhibits a visible light transmittance Tv of 5% or lower, small variation in visible light transmittance and an excellent appearance when incorporated in a laminated glass together with two clear glass plates in conformity with JIS R3202 (1996), and a colored laminated glass produced using the interlayer film for a colored laminated glass. Provided is an interlayer film for a colored laminated glass having, recesses on at least one surface, and exhibiting a visible light transmittance Tv of 5% or lower when incorporated in a laminated glass together with two clear glass plates in conformity with JIS R3202 (1996), the interlayer film for a colored laminated glass including a laminate of at least two layers including a first resin layer containing a thermoplastic resin and a colorant and a second resin layer containing a thermoplastic resin and no colorant, the elastic modulus E1 of the first resin layer and the elastic modulus B2 of the second resin layer having a ratio E1/E2 of 1.25 or more, the thickness t1 of the first resin layer and the thickness t2 of the second resin layer having a ratio t1/t2 of 2.0 or less.
