    摘要： The invention relates to divalent immonium salts which are near infrared dyes of the formula (I). (R.sub.2 NAr).sub.2 --N.sup.+ .dbd.Ar'.dbd.N.sup.+ R.sub.2 +2X.sup.-(I) wherein: R.dbd.C.sub.1 to C.sub.6 alkyl; Ar=divalent phenyl which may or may not be ring substituted with one or more alkyl, alkoxy, halogen, nitro, cyano or carboalkoxy groups; Ar'=quinoidal phenyl which may or may not be ring substituted with one or more alkyl, alkoxy, halogen, nitro, cyano or carboalkoxy groups; and X=an anion of a strong acid. A double charged dye cation having an SbF.sub.6 anion associated with the dye can act both a near IR dye and an epoxy curative.

    摘要翻译： 本发明涉及作为式（I）的近红外染料的二价亚硝酸盐。 （R2NAr）2-N + = Ar'= N + R2 + 2X-（I）其中：R = C1-C6烷基; Ar =可以被一个或多个烷基，烷氧基，卤素，硝基，氰基或烷氧基取代的二价苯基; Ar'=喹啉基苯基，其可以或不被一个或多个烷基，烷氧基，卤素，硝基，氰基或烷氧基取代的环。 X =强酸的阴离子。 具有与染料相关的SbF 6阴离子的双电荷染料阳离子可以作用于近红外染料和环氧固化剂。

    摘要： Dye-donor element for use according to thermal dye transfer methods, said element comprising a support having thereon a dye/binder layer comprising a 1,4-quinonediimine cyan dye, which may carry a fused on aromatic, alicyclic, or heterocyclic ring system, wherein the hydrogen atom of the 1-imino function is substituted by a carboxylic acyl group, a substituted carboxylic acid group, an alkyl ester group, a substituted alkyl ester group, an aryl ester group, a substituted aryl ester group, a carbamoyl group, a substituted carbamoyl group, a substituted phosphono group, a substituted phosphinyl group, a substituted sulphonyl group, a sulpho group, a substituted sulpho group, a sulphamoyl group, or a substituted sulphamoyl group, the hydrogen atom of the 4-imino function being substituted by a p-aminoaryl group or a substituted p-aminoaryl group.
