Photocurable composition and method for manufacturing film

A photocurable composition which can be cured using light while being in contact with a mold to manufacture a film, the photocurable composition comprising:

• a polymerizable compound;
• a photopolymerization initiator;
• and
• a photosensitive gas generating agent having a photostimulation responsive portion,
• wherein the photosensitive gas generating agent has a repeating structure including at least one alkylene oxide chain and generates a gas from the photostimulation responsive portion by light irradiation,
• wherein the photosensitive gas generating agent includes a compound represented by the following general formula (2):
• RG1-XA—(O—RA—)n—XB—RG1′ (2)
• where in the formula (2), RG1 and RG1′ each represent a monovalent functional group functioning as the photostimulation responsive portion and are optionally identical to or different from each other;
• XA and XB each represent a divalent linking group and are optionally identical to or different from each other;
• RA represents a divalent alkylene group;
• and n is an integer of 1 or more.
