Manufacturing methods of transfer films, laminates, and optical waveguides; photosensitive components; polymers; optical waveguides

Abstract

The first objective of this invention is to provide a transfer film capable of forming an optical waveguide that can be alkaline developed and achieves low light propagation loss. Furthermore, the second objective of this invention is to provide a laminate, a method for manufacturing an optical waveguide, a photosensitive composition, a polymer, and an optical waveguide. A transfer film comprises a temporary support and a photosensitive composition layer, wherein the aforementioned photosensitive composition layer comprises a polymer having repeating units represented by formula (1), free radical polymerizable groups, and carboxyl groups or salts thereof.
