DYESTUFFS ARE PROVIDED CONTAINING AN ATOM GROUPING OF THE FOLLOWING FORMULAE:
-N(+)(=(C(-)-C(-))N=C
-N(-(C(-)=C(-))N-C IN WHICH X REPRESENTS A MONOVALENT ANION, Y REPRESENTS AN OXYGEN OR SULPHUR ATOM AND N REPRESENTS 1 OR 2. PROCESSES FOR THE PREPARATION OF THESE DYESTUFFS ARE ALSO PROVIDED.
摘要:
A dye and a heat transfer sheet for use in a heat transfer printing method employing a sublimable dye, capable of producing an image which has a sufficiently high density and is excellent in sharpness, fastness properties and, in particular, resistance to light are provided. The dye has the following formula (I): ##STR1## The heat transfer sheet includes a substrate sheet, and a dye layer including the dye having formula (I), provided on one surface of the substrate sheet.
摘要:
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 benz-cd-indole merocyanine blue dye having the formula: ##STR1## wherein: R represents hydrogen; a substituted or unsubstituted alkyl group having from 1 to about 8 carbon atoms; a substituted or unsubstituted alkenyl group having from about 2 to about 8 carbon atoms; or a substituted or unsubstituted aralkyl group having from about 7 to about 12 carbon atoms; andZ represents the atoms necessary to complete a 5- or 6-membered carbocyclic or heterocyclic ring.
摘要:
Dyestuffs of the formula ##STR1## wherein R represents hydrogen or optionally substituted alkyl,A represents ##STR2## wherein R.sup.1 represents hydrogen, optionally substituted alkyl or cycloalkyl andR.sup.2 represents optionally substituted alkyl which can close a ring to ring B, aralkyl or aryl orR.sup.1 and R.sup.2, together with the N atom, form a ring,D and E represent hydrogen, optionally substituted alkyl or alkenyl and D additionally represents aryl, aralkyl, aralkenyl or a heterocyclic radical, or D and E, together with the C atom, form a ring andAn.sup.- represents an anion,are used for pulp-coloring paper and dyeing cationically dyeable fibres.
