摘要:
The invention is directed to a process and more particularly, to utilizing polymer solutions to make thick film compositions. In one embodiment the process is directed to the formation of photoimageable thick film compositions for use in photo-patterning methods to make photoimageable electrodes in flat panel display applications, including plasma display panels (PDP). Polymer solutions are obtained by directly polymerizing desired monomers in a desired solvent to form a desired polymer, rather than by dissolving a pre-made polymer in a desired solvent. Other ingredients are added to the polymer solution to directly form thick film pastes, including photoimageable thick film pastes.
