▎ 摘  要

NOVELTY - Intermediate film (11) contains a pigment, in which the value YId obtained by subtracting a yellow index YIp calculated from a parallel transmittance from a yellow index YIt calculated from a total transmittance in the intermediate film for laminated glasses is -1 or more. USE - The intermediate film is used for laminated glasses (claimed) which is used for automobiles, railroad vehicles, aircraft, ships, and buildings. ADVANTAGE - The film makes bluish fogging unlikely to occur, and utilizes pigment to provide heat shielding property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a laminated glass comprising a first laminated glass member, a second laminated glass member, and the above-mentioned interlayer film, where the interlayer film is arranged between the first laminated glass member and the second laminated glass member. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view schematically showing an interlayer film for laminated glass. First layer (1) First surface (1a) Second surface (1b) Second layer (2) Third layer (3) Interlayer film (11)
