Abstract
A thermally-transferred color filter array element comprising a support having thereon a polymeric dye image-receiving layer containing a thermally-transferred image comprising a repeating pattern of colorants of a maleimide blue dye having the formula: ##STR1## wherein: R.sup.1 and R.sup.2 each independently represents hydrogen; a substituted or unsubstituted alkyl group having from 1 to about 8 carbon atoms; a cycloalkyl group having from about 5 to about 8 carbon atoms; or a substituted or unsubstituted alkenyl group having from about 2 to about 8 carbon atoms; PA0 R.sup.1 and R.sup.2 may represent the elements which may be taken together to form a 5- or 6-membered heterocyclic ring; PA0 each Y independently represents hydrogen; a substituted or unsubstituted alkyl group having from 1 to about 8 carbon atoms; an alkoxy group OR.sup.1 ; halogen; or two adjacent Y's may represent the atoms which may be taken together to form a fused aromatic ring; PA0 n is 0 to 4; PA0 the position of Y ortho to the nitrogen may also be combined with R.sup.1 to form a 5- or 6-membered non-aromatic, single or double nitrogen-containing, heterocyclic ring, thus forming a fused ring system; and PA0 X …
