-i- MIXTURE OF YELLOW AND MAGENTA DYES TO FORM A RED HUE FOR COLOR FILTER ARRAY ELEMENT 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 mixture of a yellow dye and a magenta dye to form a red hue, said yellow dye having the formula: Image wherein R is a substituted or unsubstituted alkyl group of from 1 to about 10 carbon atoms; a cycloalkyl group of from about 5 to about 7 carbon atoms; or represents the atoms which when taken together with Z forms a 5- or 6-membered ring; R1 is an alkylene or substituted alkylene group; X is -OJO-, -OJ-, -JO-, -OJNR3-, -NR3J-, -NR3JNR3, -JNR3- or -NR3JO-; J is CO or SO2; R3 is hydrogen; a substituted or unsubstituted alkyl group of from 1 to about 10 carbon atoms; a substituted or unsubstituted aryl group of from about 6 to -ii- about 10 carbon atoms; or represents the atoms which when taken together with R2 forms a 5- or 6-membered ring; R2 is a substituted or unsubstituted alkyl group of from 1 to about 10 carbon atoms; a cycloalkyl group of from about 5 to about 7 carbon atoms; a substituted or unsubstituted aryl group of from about 6 to about 10 carbon atoms; or represents the atoms which when taken together with R3 forms a 5- or 6-membered ring; Z is hydrogen or represents the atoms which when taken together with R forms a 5- or 6-membered ring; Y is a substituted or unsubstituted alkyl or alkoxy group of from 1 to about S carbon atoms or halogen; and n is a positive integer from 1 to 4; and said magenta dye having the formula: II Image wherein R4 and R5 may each independently be hydrogen, substituted or unsubstituted alkyl or allyl of from 1 to about 6 carbon atoms, substituted or unsubstituted cycloalkyl of from about 5 to about 7 carbon atoms, substituted or unsubstituted aryl of from about S to about 10 carbon atoms; or R4 and R5 may be taken together to form a ring; or a 5- or -iii- 6-membered heterocyclic ring may be formed with R4 or R5, the nitrogen to which R4 or R5 is attached, and either carbon atom ortho to the carbon attached to said nitrogen atom; R6 may be hydrogen, substituted or unsubstituted alkyl of from 1 to about 6 carbon atoms, substituted or unsubstituted aryl of from about 5 to about 10 carbon atoms, alkylthio or halogen; B may be substituted or unsubstituted alkyl of from 1 to about 6 carbon atoms, substituted or unsubstituted aryl of from about 5 to about 10 carbon atoms or NHA, where A is an acyl or sulfonyl radical; and Q may be cyano, thiocyanato, alkylthio or alkoxycarbonyl.
