A photocurable composition capable of producing a micropattern-formed product efficiently, which is excellent in physical properties such as heat resistance, chemical resistance, releasability and optical characteristics (transmittance and low refractive index), and a process for producing a micropattern-formed product, capable of highly precisely transferring a micropattern of a mold to its surface are provided.
A photocurable composition which comprises from 50 to 98 mass% of a monomer containing no fluorine atom and having a viscosity at 25°C of from 0.1 to 100 mPa·s, from 0.1 to 45 mass% of a fluoromonomer, from more than 0.1 to 20 mass% of a fluorinated surfactant and/or a fluoropolymer and from 1 to 10 mass% of a photopolymerization initiator, and contains substantially no solvent. A process for producing a micropattern-formed product comprising a cured product having a micropattern of a mold transferred on its surface, or such a micropattern-formed product integrated with a substrate, which uses the photocurable composition, a substrate and a mold having a micropattern.
