Abstract
Abstract A thermally-transferred color filter array element comprising a transparent support having thereon a thermally-transferred image comprising a repeating mosaic pattern of colorants in a receiving layer, one of the colorants being a phenyl or thienyl azoaniline blue dye. In a preferred embodiment, the dye has the following formula: ##STR1## wherein R 1 and R 2 each independently represents hdyrogen; a substituted or unsubstituted alkyl group of from 1 to about 6 carbon atoms; a cycloalkyl group of from about 5 to about 7 carbon atoms; or a substituted or unsubstituted aryl or hetaryl group of from about 6 to about 10 carbon atoms; R 3 represents hydrogen or a substituted or unsubstituted alkyl or alkoxy group of from 1 to about 10 carbon atoms; R 2 may be taken together with R 1 to form a 5- or 6-membered ring; R 1 or R 2 may be combined with R 3 or may be joined to the carbon atom of the benzene ring at a position ortho to the position of attachment of the anilino nitrogen to form a 5- or 6-membered ring; R 4 represents hydrogen, a substituted or unsubstituted alkyl or alkoxy group of from 1 to about 10 carbon atoms, halogen, sulfonamido or acylamido; R 5 represents nitro, cyano, fluorosulfonyl, alkylsulfonyl, arylsulfonyl, acyl, alkoxycarbonyl, carbamoyl, sulfamoyl, trifluoromethyl or halogen; R 6 represents nitro, cyano, acyl, trifluoroacetyl, dicyanovinyl or tricyanovinyl; and J represents --S-- or --CH═CR 5 --.
