Mischung von gelben und purpurroten Farbstoffen für die Erzeugung eines roten Tones für ein Farbfilterreihenelement.

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 magenta dye to form a red hue, said yellow dye having the formula: wherein R is a substituted or unsubstituted alkyl group of from 1 to 10 carbon atoms; a cycloalkyl group of from 5 to 7 carbon atoms; or represents the atoms which when taken together with Z forms a 5- or 6-membered ring; R<1> is an alkylene or substituted alkylene group; X is -OJO-, -OJ-, -JO-, -OJNR<3>-, -NR<3>J-, -NR<3>JNR<3>, -JNR<3>- or -NR<3>JO-; J is CO or SO2; R<3> is hydrogen; a substituted or unsubstituted alkyl group of from 1 to 10 carbon atoms; a substituted or unsubstituted aryl group of from 6 to 10 carbon atoms; or represents the atoms which when taken together with R<2> forms a 5- or 6-membered ring; R<2> is a substituted or unsubstituted alkyl group of from 1 to 10 carbon atoms; a cycloalkyl group of from 5 to 7 carbon atoms; a substituted or unsubstituted aryl group of from 6 to 10 carbon atoms; or represents the atoms which when taken together with R<3> 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 6 carbon atoms or halogen; and n is a positive integer from 1 to 4; and said magenta dye having the formula: wherein R<4> and R<5> may each independently be hydrogen, substituted or unsubstituted alkyl or allyl of from 1 to 6 carbon atoms, substituted or unsubstituted cycloalkyl of from 5 to 7 carbon atoms, substituted or unsubstituted aryl of from 5 to 10 carbon atoms; or R<4> and R<5> may be taken together to form a ring; or a 5- or 6-membered heterocyclic ring may be formed with R<4> or R<5>, the nitrogen to which R<4> or R<5> is attached, and either carbon atom ortho to the carbon attached to said nitrogen atom; R<6> may be hydrogen, substituted or unsubstituted alkyl of from 1 to 6 carbon atoms, substituted or unsubstituted aryl of from 5 to 10 carbon atoms, alkylthio or halogen; B may be substituted or unsubstituted alkyl of from 1 to 6 carbon atoms, substituted or unsubstituted aryl of from 5 to 10 carbon atoms or NHA, where A is an acyl or sulfonyl radical; and Q may be cyano, thiocyanato, alkylthio or alkoxycarbonyl.
