Problems solved by technology

However, methyl methacrylate is a hard monomer. When this binary copolymer system is used as an alkali-soluble resin, the pattern after exposure may be too hard, and the pattern may be peeled off during development, causing defects such as over-display and trimming. Reduce the flatness of electrode lines

Abstract

The invention relates to a photosensitive resin composition for a plasma panel electrode, which is characterized in that: the resin composite comprises (1) 40-80wt percent of conducting metal powder; (2) 5-20wt percent of low melting point glass powder; (3) 10-50wt percent of organic matter ingredient; wherein the organic matter ingredient comprises (1) 5-50wt percent of alkaline solubility resin based on the organic matter ingredient; (2) a polymer monomer, a polymer initiator and volatile inert solvent, and the alkaline solubility resin copolymer is terpolymer, and the terpolymer is composed of methyl methacrylate, methacrylic acid and a third monomer which is not based on the methyl methacrylate and the methacrylic acid.

Description

Technical field [0001] The present invention relates to the field of gas discharge, in particular to a photosensitive resin composition used for bus electrodes and address electrodes of a plasma display panel. Background technique [0002] A plasma display panel is a flat panel display that uses plasma discharge light to display images and information. Compared with liquid crystal displays, plasma displays have a faster response speed and are easy to be processed into large sizes, and are gradually becoming the direction of large-size flat panel displays. Each display unit of the plasma display is filled with phosphors, and there are ITO electrodes for discharge on the front substrate, and the silver bus electrodes are covered on the ITO electrodes to increase the conductivity. When the display is working, the address electrodes on the back substrate determine the light-emitting unit, and the ITO electrode discharges the ionized gas, thereby exciting the phosphor in the barrier ...
