Abstract
Abstract A color filter element comprising at least two differently colored sets of color arrays and having a barrier layer separating the sets to prevent color contamination between the sets is disclosed. The barrier layer is an optically clear polymerized, crosslinked hexaalkoxymethylmelamine monomer. The element is useful in color imaging devices.
