    • A hard coat film comprises a hard coat layer formed by coating at least one face of a substrate with a coating fluid and curing the obtained coating layer by irradiation with an ionizing radiation. The coating fluid comprises a component for forming a hard coat layer comprising (A) a compound which is formed by bonding an organic compound having a polymerizable unsaturated group to fine particles of silica, (B) an ester of (meth)acrylic acid having an alicyclic structure and (C) a compound having at least two polymerizable unsaturated groups and at least one aryl group in a molecule. The hard coat layer comprises 20 to 60% by weight of silica and has a refractive index of 1.53 or greater. The hard coat film exhibits excellent scratch resistance, little shrinking by curing and little shrinking and curling under high temperature and humidity and forms no optical interference fringes.
    • 硬涂膜包括通过用涂布液涂布基材的至少一个表面而形成的硬涂层,并且通过用电离辐射照射固化所获得的涂层。 涂布流体包括用于形成硬涂层的组分,其包含(A)通过将具有可聚合不饱和基团的有机化合物与二氧化硅细颗粒结合而形成的化合物,(B)具有(甲基)丙烯酸的 脂环结构和(C)分子中具有至少两个可聚合不饱和基团和至少一个芳基的化合物。 硬涂层包含20至60重量%的二氧化硅,折射率为1.53或更大。 硬涂膜具有优异的耐擦伤性,通过固化几乎不收缩,并且在高温和高湿下几乎不收缩和卷曲,并且不形成光学干涉条纹。
