-i- MIXTURE OF YELLOW AND CYAN DYES TO FORM A GREEN HUE FOR COLOR FILTER ARRAY ELEMENT 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 mixture of a yellow dye and a cyan dye to form a green hue, said yellow dye having the formula: I wherein: R1 and R2 each independently represents hydrogen; 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; a substituted or unsubstituted aryl or hetaryl group of about 6 to about 10 carbon atoms; or can be taken together to form, along with the nitrogen to which they are attached, a 5- or 6-membered ring; or either or both of R1 and R2 can be joined to a carbon atom of the aromatic ring at a position ortho to the position of attachment of the anilino nitrogen to form a 5- or 6-membered ring; R3 represents hydrogen or halogen; Y represents hydrogen; halogen; cyano; a substituted or unsubstituted alkyl or alkoxy -ii-group of from 1 to about 6 carbon atoms; a substituted or unsubstituted aryl or hetaryl group of from about 6 to about 10 carbon atoms; aryloxy; acylamido, alkylsulfonamido; or arylsulfonamido; and n is a positive integer from 1 to 5; and said cyan dye having the formula: II wherein R4 and R5 each independently represents hydrogen; 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; R6 represents hydrogen or a substituted or unsubstituted alkyl or alkoxy group of from 1 to about 10 carbon atoms; R5 may be taken together with R4 to form a 5- or 6-membered ring; R4 or R5 may be combined with R6 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; R7 represents hydrogen, a substituted or unsubstituted alkyl or alkoxy group of from 1 to about 10 carbon atoms, halogen, sulfonamido or acylamido; R8 represents nitro, cyano, fluorosulfonyl, alkylsulfonyl, arylsulfonyl, -iii-acyl, alkoxycarbonyl, carbamoyl, sulfamoyl, trifluoromethyl or halogen; R9 represents nitro, cyano, acyl, trifluoroacetyl, dicyanovinyl or tricyanovinyl; and J represents -S- or -CH=CR8.
