PASTE COMPOSITION FOR PRINTING

摘要

A paste composition for printing is provided to realize optimized offset printing characteristics required for directly forming a micropattern, and to avoid a problem of retreating materials removed from a development step in a conventional photolithographic process for forming an electrode pattern of a plasma display panel. A paste composition for printing comprises: (a) 5-30 wt% of an acrylate polymer resin; (b) 5-30 wt% of a crosslinkable oligomer; (c) 0.1-5 wt% of a photopolymerization initiator; and (d) 50-85 wt% of metal powder. The acrylate polymer resin is obtained by polymerizing 20-50 wt% of an unsaturated carboxylic acid monomer, 10-30 wt% of an aromatic monomer, and 20-60 wt% of at least one monomer selected from the group consisting of 2-hydroxyethyl (meth)acrylate, 2-hydroxyoctyl (meth)acrylate, methyl (meth)acrylate, ethyl (meth)acrylate and n-butyl acrylate in the presence of a solvent.
