Title:
PHOTOSENSITIVE ELECTRIC CONDUCTIVE PASTE
Document Type and Number:
Japanese Patent JP3672105
Kind Code:
B2
Abstract:
PURPOSE: To provide a conductor pattern having a fine line width by exposing a film formed of a predetermined photosensitive conductive paste via a pattern mask, and applying developing and the like with a developer.
CONSTITUTION: Exposure is conducted via a pattern mask onto a film formed by application of a photosensitive conductive paste including a conductive metallic component grain, acrylic copolymer having an ethylene unsaturated group in a side chain, photoreactive polymerizing compound, and a photo polymerization initiator. Then, developing is conducted with a developer to form a pattern, followed by a heat treatment, and a conductor pattern having a fine line width of 100μm or less is obtained.
