Mixture of yellow and cyan dyes to form a green hue for color filter array element.

摘要

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, characterized in that said yellow dye has the formula: wherein: R<1> and R<2> each independently represents hydrogen; a substituted or unsubstituted alkyl group of from 1 to 6 carbon atoms; a cycloalkyl group of from 5 to 7 carbon atoms; a substituted or unsubstituted aryl or hetaryl group of 6 to 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 R<1> and R<2> 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; R<3> represents hydrogen or halogen; Y represents hydrogen; halogen; cyano; a substituted or unsubstituted alkyl or alkoxy group of from 1 to 6 carbon atoms; a substituted or unsubstituted aryl or hetaryl group of from 6 to 10 carbon atoms; aryloxy; acylamido, alkylsulfonamido; or arylsulfonamido; and n is a positive integer from 1 to 5; and said cyan dye has the formula: wherein R<4> and R<5> each independently represents hydrogen; a substituted or unsubstituted alkyl group of from 1 to 6 carbon atoms; a cycloalkyl group of from 5 to 7 carbon atoms; or a substituted or unsubstituted aryl or hetaryl group of from 6 to 10 carbon atoms; R<6> represents hydrogen or a substituted or unsubstituted alkyl or alkoxy group of from 1 to 10 carbon atoms; R<5> may be taken together with R<4> to form a 5- or 6-membered ring; R<4> or R<5> may be combined with R<6> 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<7> represents hydrogen, a substituted or unsubstituted alkyl or alkoxy group of from 1 to 10 carbon atoms, halogen, sulfonamido or acylamido; R<8> represents nitro, cyano, fluorosulfonyl, alkylsulfonyl, arylsulfonyl, acyl, alkoxycarbonyl, carbamoyl, sulfamoyl, trifluoromethyl or halogen; R<9> represents nitro, cyano, acyl, trifluoroacetyl, dicyanovinyl or tricyanovinyl; and J represents -S- or -CH=CR<8>-. o
