Curable composition for photoimprint, and method for producing cured product using same

A method for producing a cured product, comprising using a curable composition for photoimprints comprising a photopolymerizable monomer, a polymerization initiator and a compound of the following formula (1), wherein the content of compounds having a molecular weight of at least 1000 is at most 10% by mass of all the solid content therein, and the content of the compound of the formula (1) is from 0.3 to 10.0% by mass of all the solid content therein:

• wherein Z represents an aliphatic hydrocarbon group;
• R1 and R2 each independently represent a hydrogen atom or a substituent;
• R3 and R4 each independently represent a methyl group, an ethyl group, a methoxy group or an ethoxy group;
• and R5 represents a methoxy group or an ethoxy group.

A method for producing a cured product, comprising:

• applying a curable composition for photoimprints onto a substrate to form a patterning layer thereon, wherein the curable composition for photoimprints comprises a photopolymerizable monomer, a polymerization initiator and a compound of the following formula (1), wherein the content of compounds having a molecular weight of at least 1000 is at most 10% by mass of all the solid content therein, and the content of the compound of the formula (1) is from 0.3 to 10.0% by mass of all the solid content therein:
• wherein Z represents an aliphatic hydrocarbon group;
• R1 and R2 each independently represent a hydrogen atom or a substituent;
• R3 and R4 each independently represent a methyl group, an ethyl group, a methoxy group or an ethoxy group;
• and R5 represents a methoxy group or an ethoxy group,
• pressing a mold against the surface of the patterning layer, and
• irradiating the patterning layer with light.
