ABSTRACT:
A color imaging device having a certain color filter array is disclosed. The color filter array is of the "wash-off" type wherein the individual filter elements are formed by dyeing tiny elements of a dyeable composition. In order to form a barrier so that the process of dyeing subsequent filter elements does not affect a previous set of filter elements, the first set of filter elements is treated with a metal salt of a long-chain fatty acid. The dyeable composition comprises at least one compound having coordination sites for the metal of the long-chain fatty acid salt.
