Zusammenfassung:To provide a resin composition for an intermediate film for laminate glass which improves in weather resistance.SOLUTION: A resin composition that is used for forming an intermediate film for laminate glass contains a resin (A), a dye (B), and an ultraviolet absorber (C). In total light transmittance of the laminate glass composed of the resin composition, a light transmittance at a wavelength of 400 nm is 65% or less, a wavelength having a minimal light transmittance is 570 nm or more and 605 nm or less in a range of a wavelength of 420 nm or more and 720 nm or less, and a light transmittance at the wavelength having a minimal light transmittance is 1% or more and 50% or less in a range of a wavelength of 570 nm or more and 605 nm or less.SELECTED DRAWING: Figure 1 【課題】耐候性が向上した合わせガラス中間膜用樹脂組成物を提供する。【解決手段】合わせガラス中間膜を形成するために用いられる樹脂組成物であって、樹脂(A)と、色素(B)と、紫外線吸収剤(C)と、を含み、前記樹脂組成物により構成される合わせガラスの全光線透過率において、波長400nmにおける光線透過率が65%以下であり、波長420nm以上720nm以下の範囲において、光線透過率が極小となる波長が波長570nm以上605nm以下であり、波長570nm以上605nm以下の範囲において、光線透過率が極小となる波長における光線透過率が1%以上50%以下である透過スペクトルを有する。【選択図】図1
