Abstract

A photocurable composition which decreases a mold releasing force is provided. The photocurable composition is a photocurable composition which is cured using light while being in contact with a mold having a surface in which a concavo-convex pattern is formed so as to manufacture a film having a concavo-convex pattern and which includes a polymerizable compound, a photopolymerization initiator, and a photosensitive gas generating agent having a photostimulation responsive portion. The photosensitive gas generating agent has a repeating structure containing at least one alkylene oxide chain and generates a gas from the photostimulation responsive portion by light irradiation.
