Title:
METHOD FOR PRODUCING MULTILAYER PATTERN FORMED BASE AND METHOD FOR PRODUCING TOUCH PANEL
Document Type and Number:
WIPO Patent Application WO/2017/208842
Kind Code:
A1
Abstract:
A method for producing a multilayer pattern formed base, which comprises a first light exposure step wherein a laminate that is obtained by sequentially laminating a base A, a photosensitive layer B and a transparent electrode layer C is exposed to light, a coating step wherein the surface of the laminate is coated with a photosensitive conductive paste D so as to obtain a photosensitive conductive film D, a second light exposure step wherein the photosensitive conductive film D is exposed to light, and a development step wherein the laminate and the photosensitive conductive film D are collectively developed at the same time, thereby obtaining a multilayer pattern that is composed of a transparent electrode pattern C and a conductive pattern D, and wherein the photosensitive layer B contains a photosensitive resin and a photopolymerization initiator, while the photosensitive conductive paste D contains conductive particles, a photosensitive resin and a photopolymerization initiator. Consequently, the present invention provides a method for producing a multilayer pattern formed base, which is able to suppress the generation of a residue during removal of an unexposed part by dissolution, while maintaining adhesion between a conductive pattern and a photosensitive resin layer formed on a base, and which has excellent ion migration resistance between the conductive pattern and the photosensitive resin layer.
