摘要： Compounds of Formula (1) and salts thereof: wherein: A is optionally substituted phenyl; R1 and R2 are each independently optionally substituted alkyl or optionally substituted alkoxy; and R4 and R5 are each independently H, optionally substituted alkyl or optionally substituted aryl; provided that (i) at least one of R1 and R2 carries an —OH group; and (ii) A is not of the formula: wherein m is 1, 2 or 3. The compounds are useful as dyes for ink jet printing inks.

摘要： A thermal transfer printing sheet comprising a substrate having a coating comprising a binder and a water insoluble dye of Formula I: ##STR1## wherein; R is the residue of an active methylene compound;X is hydrogen; halogen; optionally substituted alkyl; optionally substituted aryl or optionally substituted heteroaryl;Y is --S-- or a group of the formula N--R.sup.1 wherein R.sup.1 represents hydrogen or an optionally substituted C.sub.1-4 -alkyl; andE is the residue of a coupling component.The dyes are suitable for use in dye diffusion thermal transfer printing of the type where a transfer sheet is placed in contact with the material to be printed and selectively heated in accordance with a pattern information signal whereby dye from the selectively heated regions of the transfer sheet is transferred to the material to be printed and forms a pattern thereon the shape and density of which is in accordance with the pattern and intensity of heat applied to the transfer sheet.
