Title:
INSULATING PASTE FOR SUPPORTING ELECTRODE LAYER, TOUCHSCREEN, AND TOUCHSCREEN MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/094693
Kind Code:
A1
Abstract:
The present invention provides an insulating paste for supporting an electrode layer. The insulating paste is suitable for use in a process where a conductive paste is applied, exposed through a photomask, and developed to form a pattern. The insulating paste can be developed without generating residue such as silver microparticles, adheres well to the electrode layer, and will not impede the visibility of the touch position on a touchscreen. The insulating paste for supporting an electrode layer according to the present invention comprises a carboxyl-group-containing resin, a polyfunctional monomer, and a photopolymerization initiator. The photopolymerization initiator content is 3.5-20 mass%, the carboxyl-group-containing resin content is 20-35 mass%, and the weight average molecular weight of the carboxyl-group-containing resin is 20,000-120,000.
