Title:
PHOTOCURABLE COMPOSITION FOR NANOIMPRINT AND METHOD FOR PRODUCING OPTICAL COMPONENT
Document Type and Number:
WIPO Patent Application WO/2017/195548
Kind Code:
A1
Abstract:
Provided is a photocurable composition for nanoimprint, which has excellent fast curing properties and coating uniformity, and which is capable of exhibiting excellent shape transferability, while suppressing swelling of a silicone mold in a nanoimprint method. A photocurable composition for nanoimprint according to the present invention contains the component (A), the component (B), the component (C) and the component (D) described below, and is configured such that, relative to the total amount of curable compounds contained in the photocurable composition, the content of the component (A) is 10-60% by weight, the content of the component (B) is 10% by weight or more and the content of the component (C) is 10% by weight or more. Component (A): an alicyclic epoxy compound which has at least one partial structure represented by formula [a], while having a molecular weight of 400 or more and an SP value of Fedors of 9.0 (cal/cm3)1/2 or more (In formula [a], R1-R9 and X are as defined in the description.) Component (B): an oxetane compound which has an SP value of Fedors of 10.0 (cal/cm3)1/2 or more or a molecular weight of 400 or more (excluding compounds that fall under the category of the component (A)) Component (C): a cationic curable compound having a number average molecular weight of 1,000 or more (excluding compounds that fall under the category of the component (A) or the component (B)) Component (D): a photopolymerization initiator
