Document Type and Number:
WIPO Patent Application WO/2020/162131
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of providing: a method for producing a metal pattern by processing a substrate having a metal layer at a surface thereof, using photosensitive fibers having a specific composition; a production method for a metal pattern; and a composition for producing the photosensitive fibers, and preferably providing a transparent interconnect pattern that is low-cost and is flexible. [Solution] The present invention provides a photosensitive fiber containing a positive photosensitive material. The positive photosensitive material may contain a novolac resin or the like. The production method for a metal pattern according to the present invention includes a first step for forming a fiber layer containing photosensitive fibers on a substrate having a metal layer at a surface thereof, a second step for exposing the fiber layer with light through a mask, a third step for developing the fiber layer using a developer liquid to form a photosensitive fiber pattern, and a fourth step for etching the metal layer using an etchant, and removing the photosensitive fibers, to form a reticulated metal pattern.
