Claims
- 1. A method for preparing an ink for the manufacture of an EL lamp, said method comprising the steps of:providing a solvent selected from the group consisting of DMAC, DMF, THF, DMSO, NMP, acetone, and mixtures thereof; dissolving a binder consisting essentially of low molecular weight PVDF/HFP copolymer resin in the solvent to form a solution of 5-55% by weight binder; and adding to the solution a filler selected from the group consisting of Zn:S particles doped to produce electroluminescence, BaTiO3 particles, TiO2 particles, SrTiO3 particles, CaTiO3 particles, carbon particles, and silver particles, to form a slurry.
- 2. The method as set forth in claim 1 and further including the step of:adding 0-5% by weight of flow controller to the ink.
- 3. The method as set forth in claim 1 and further including the step of:adding 0-50% by weight of an acrylic resin to the ink.
