본 발명은, JIS R3202 (1996) 에 준거한 2 장의 클리어 유리를 사용하여 합판 유리를 제조했을 때에, 가시광선 투과율 (Tv) 이 5 % 이하이면서, 부위에 따른 가시광선 투과율의 편차가 작고, 미관이 우수한 착색 합판 유리용 중간막, 및 그 착색 합판 유리용 중간막을 사용한 착색 합판 유리를 제공하는 것을 목적으로 한다. 본 발명은, JIS R3202 (1996) 에 준거한 2 장의 클리어 유리를 사용하여 합판 유리를 제조했을 때에, 가시광선 투과율 (Tv) 이 5 % 이하인 착색 합판 유리용 중간막으로서, 열가소성 수지와 착색제를 함유하는 제 1 수지층과, 열가소성 수지를 함유하고, 착색제를 함유하지 않는 제 2 수지층의 적어도 2 층의 적층체로 이루어지고, 상기 제 1 수지층의 두께의 최대값 (t1max) 과 두께의 최소값 (t1min) 의 차 (Δt1) 와, 상기 제 1 수지층의 평균 두께의 비 (Δt1/제 1 수지층의 평균 두께) 가 0.30 이하인 착색 합판 유리용 중간막이다.

    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 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 first resin layer satisfying a ratio of a difference Δtin thickness between the maximum value tand the minimum value tto an average thickness (Δt/average thickness of first resin layer) of 0.30 or less.
