Photosensitive transfer material, substrate having photosensitive low refractive index transfer layer, method for producing photosensitive low refractive index transfer layer, method for forming permanent film, and method for manufacturing optical device

摘要

It is an object of the present invention to provide a photosensitive transfer material having a low refractive index, high light transmission efficiency, and capable of obtaining a layer excellent in in-plane film thickness uniformity after transfer. The photosensitive transfer material of the present invention has at least a photosensitive low refractive index material layer on a support, and the photosensitive low refractive index material layer is composed of (Component A) hollow or porous particles and (Component B) A photopolymerization initiator, (Component C) a polymer having a polymerizable functional group, and (Component D) monomer. Further, the substrate of the present invention has a photosensitive low refractive index transfer layer obtained by transferring the photosensitive low refractive material layer from the photosensitive transfer material.
