Abstract:
In an imprint method in a condensable gas atmosphere, the force (mold releasing force) required to separate a mold from a resist cured film (mold release) has been large. A photocurable composition for performing imprint in an atmosphere containing a condensable gas includes a component (A) which is a (meth)acrylate monomer, a component (B) which is a photopolymerization initiator; and a component (C) which is a mold releasing agent. The saturated solubility of the component (C) in the condensable gas at 5 degrees (Celsius) and 1 atm is 50% by weight or more, the condensable gas being in a liquid state at 5 degrees (Celsius) and 1 atm.
