Abstract

The purpose of this invention is to provide: a hard-coat composition with which it is possible to produce a hard-coat layer having excellent hardness and abrasion-resistance when cured, and having excellent moldability during processing; and a laminate film and the like having such a hard-coat composition. This problem is solved by a curable hard-coat composition containing a (meth)acryloyl polymer and inorganic oxide nanoparticles, wherein the (meth)acryloyl polymer has a (meth)acrylic equivalent of 200-500 g/eq and a weight-average molecular weight of 5,000-200,000.
