Abstract
The present invention is directed to pigment compositions with the formula BiwMnxCoyCuzO40, wherein w is between 7 and 9, x is between 3 and 13, y is between 2 and 13, z is between 0.5 and 7 and the sum of w, x, y and z is 26. The invention also is directed to thick film black pigment compositions, conductive single layer thick film compositions, black electrodes made from such black conductive compositions and methods of forming such electrodes, and to the uses of such compositions, electrodes, and methods in flat panel display applications, including alternating-current plasma display panel devices (AC PDP).
