1. A method for producing a microstructure, the method comprising the steps of:
a) preparing a mold having a relief-patterned surface; b) preparing a substrate; c) forming and sandwiching a liquid photocurable transferable material layer between the substrate and the relief-patterned surface of the mold to shape the transferable material layer; d) performing exposure of the shaped transferable material layer to convert the transferable material layer into a photocured layer; and e) demolding the photocured layer from the mold to give the microstructure, the step a) comprising
preparing the mold from a polymeric organic compound comprising siloxane bonds, the step c) comprising
forming the transferable material layer from a photocurable composition comprising:
a cationically polymerizable compound (A); anda photoacid generator (B), the cationically polymerizable compound (A) in the photocurable composition comprising at least one compound selected from the group consisting of:
compounds represented by Formula (I); andcompounds represented by Formula (II):wherein n represents an integer from 0 to 10; X is, independently in each occurrence, selected from oxygen, —CH2—, —C(CH3)2—, —CBr2—, —C(CBr3)2—, —CF2—, —C(CF3)2—, —CCl2—, —C(CCl3)2—, and —CH(C6H5)—, where, when n is 2 or more, two or more occurrences of X may be identical or different; and R1 to R18 are, identically or differently, selected from hydrogen, halogen, a hydrocarbon group optionally containing oxygen or halogen, and optionally substituted alkoxy,wherein R represents a group corresponding to a q-hydric alcohol, except for removing hydroxy group in a number of q from the alcohol; and p and q each represent, identically or differently, an integer of 1 or more. |
