One side of a substrate film
11
is coated with a coating composition containing (A) a reactive particle produced by chemically bonding an organic compound having at least one polymerizable unsaturated group in its molecule to an inorganic oxide particle, (B) a monomer or oligomer of an organic compound having at least two polymerizable unsaturated groups in its molecule, (C) an organic compound with a weight average molecular weight of at least 1500 and having at least one polymerizable unsaturated group in its molecule, and, if desired, (D) a siloxane compound having a dimethylsiloxane skeleton, and the coating composition is cured by irradiation with ionizing radiation to form a hard coat layer
12
with a thickness of 2 to 20 μm. This provides a hard coat film having adequate surface hardness and suppressed warpage.
基底薄膜的一面
11
的一面涂有涂层组合物,该涂层组合物含有 (A) 通过将分子中含有至少一个可聚合不饱和基团的有机化合物与无机氧化物粒子
化学键合而产生的活性粒子,(B) 分子中含有至少两个可聚合不饱和基团的有机化合物的单体或低聚物、(D) 具有二甲基
硅氧烷骨架的
硅氧烷化合物,通过电离辐射照射固化涂层组合物,以形成硬涂层层; (E) 具有二甲基
硅氧烷骨架的
硅氧烷化合物,通过电离辐射照射固化涂层组合物,以形成硬涂层层。
12
厚度为 2 至 20 微米。这样形成的硬涂层膜具有足够的表面硬度,并能抑制翘曲。
