PROBLEM TO BE SOLVED: To provide an organic glass laminate which suppresses whitening of an adhesive layer caused by heat generation of a heating wire layer while having excellent abrasion resistance and weather resistance, and can secure a sufficient visual field.SOLUTION: There is provided an organic glass laminate on which an organic glass substrate 1, a first adhesive layer 2, a heat wiring layer 3 partially provided, and a hard coat layer 4 are sequentially laminated, where the hard coat layer 4 is formed of a cured product of a resin composition containing a curable resin and a glass transition point of the adhesive layer 2 is set at 80-250°C, which can suppress whitening of an adhesive layer caused by heat generation of a heating wire layer while having excellent abrasion resistance and weather resistance, and can secure a sufficient visual field.SELECTED DRAWING: Figure 1 【課題】優れた耐摩耗性及び耐候性を備えつつ、電熱線層の発熱による接着層の白化が抑制され、十分な視界を確保できる有機ガラス積層体の提供。【解決手段】有機ガラス基体１、第１接着層２、部分的に設けられた電熱線層３、及びハードコート層４が順に積層された有機ガラス積層体において、ハードコート層４を、硬化性樹脂を含む樹脂組成物の硬化物で形成し、且つ接着層２のガラス転移点を８０〜２５０℃に設定することによって、優れた耐摩耗性及び耐候性を備えつつ、電熱線層の発熱による接着層の白化を効果的に抑制でき、十分な視界の確保が可能になる有機ガラス積層体。【選択図】図１
