내상성이 우수하고, 보관 시 등의 압흔이 억제되며, 프리폼 후의 표면 평활성이 우수한 인서트 성형용 하드 코트 필름을 제공한다. 기재 필름(12) 및 기재 필름(12)의 면 위에 형성된 하드 코트 층(14)을 갖고, 하드 코트 층(14)은 이온화(전리) 방사선에 의하여 경화하는 조성물로 이루어지며, 나노인덴테이션법(나노압입법)에 의하여 측정되는 하드 코트 층(14)의 압입 경도가 30 ℃에서 10 내지 200 N/㎟이고, 150 ℃에서 100 N/㎟ 이하인, 인서트 성형용 하드 코트 필름(10)으로 한다. Provided is a hard-coat film for insert molding, the film having excellent scratch resistance, suppressing indentation that could occur during storage, etc., and having excellent post-preform surface smoothness.　A hard-coat film 10 for insert molding comprises a substrate film 12 and a hard coat layer 14 formed on a surface of the substrate film 12. The hard-coat layer 14 is formed of a composition which is curable with ionization radiation. The indentation depth hardness of the hard-coat layer 14 as measured with the nanoindentation method is 10-200 N/mm2 at 30°C, and 100 N/mm2 or less at 150°C.
