Zusammenfassung:	To provide a novel optical laminate capable of suppressing color loss at edges of a polarizer under high temperature and high humidity.SOLUTION: An optical laminate provided herein comprises a polarizer, a selective light absorbing adhesive layer, and an intermediate layer laminated between the polarizer and the selective light absorbing adhesive layer in contact therewith. The intermediate layer comprises just one or more layers selected from a group consisting of a liquid crystal cured layer, alignment layer, and adhesive layer. The polarizer has iodine absorbed and aligned therein and contains 5.0 mass% or less boron. An adhesive composition forming the selective light absorbing adhesive layer contains a selective light absorbing polymer.SELECTED DRAWING: Figure 1 【課題】高温高湿下で偏光子の端部において色抜けが抑制された新規の光学積層体を提供する。【解決手段】偏光子と、光選択吸収性粘着剤層と、前記偏光子と前記光選択吸収性粘着剤層との間にこれらに接して積層された中間層と、を有する光学積層体であって、前記中間層は、液晶硬化層、配向層、及び貼合層からなる群より選択される１又は複数の層のみを有し、前記偏光子は、ヨウ素が吸着配向され、ホウ素の含有量が５．０質量％以下であり、前記光選択吸収性粘着剤層を形成する粘着剤組成物は、光選択吸収性重合体を含む、光学積層体。【選択図】図１
