    摘要： Dyestuffs of the formula ##STR1## are provided wherein R.sub.1 is hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, amino or substituted amino, amido or substituted amido or hydroxyl, alkoxy, thioalkoxy or a carboxyl group or an ester thereof, R.sub.2 represents either --N.dbd. or a linking group .dbd.CH--(CH.dbd.CH).sub.n -where n is 0, 1 or 2 and R.sub.3 is an optionally substituted heteroaromatic ring which optionally may be benzannelated, an optionally substituted benzene ring, an optionally substituted 5- or 6-membered heterocyclic or carbocyclic ring, which contains at least one hydroxyl group and may optionally be benzannelated, or R.sub.3 is a group ##STR2## wherein n is 0, 1 or 2, V is an optionally substituted 5- or 6- membered heterocyclic or carbocyclic ring, and Q is a group of the formula ##STR3## where each of W and Y are hydrogen, optionally substituted alkyl, optionally substituted cycloalkyl or optionally substituted aryl or together they represent the atoms necessary to complete a 5- or 6 -membered ring system, and X is an anion.The dyestuffs of the present invention are of use as dyes in photosensitive material which are not required to be present in the exposed and processed material. The dyestuffs of the present invention thus are useful as antihalation dyes, filter dyes and as acutance dyes.

    摘要： Disclosed are basic dyes, e.g., azo dyes and anthraquinone dyes free from sulphonic acid groups and which contain, as characteristic group, a group of the formula ##STR1## in which R and R.sub.1, independently, are substituted or unsubstituted C.sub.1-4 alkyl or are linked to form a ring, orOne of R and R.sub.1 is --NH.sub.2 or C.sub.1-4 alkoxy, the other substituted or unsubstituted alkyl,R.sub.2 and R.sub.3, independently, are hydrogen or C.sub.1-4 alkyl,Y is a bridging group,Q is unsubstituted or substituted phenyl, biphenylyl, naphthyl or ##STR2## in which R.sub.7 is ##STR3## where R.sub.8 ic C.sub.1-4 alkyl, andA.sup.- is an anion. These dyes are useful for the dyeing and printing of polymers and copolymers of acrylonitrile and asymmetrical dicyanoethylene as well as polyesters and polyamides modified to contain acid groups. The dyes build-up well and exhibit good pH stability and stability to boiling. The obtained dyeings are level and possess good fastness to light, wet treatments, solvents, heat treatments and cross-dyeing.

    摘要： A photographic element is disclosed comprised of a support and at least one layer containing a photographic imaging dye or its precursor. The imaging dye is chosen to have an absorption peak below 590 nm. An azomethine dye having an absorption peak above 700 nm is associated with the imaging dye or its precursor within the photographic layer. The azomethine dye reduces the rate of fading of the imaging dye upon exposure to visible light. A process for stabilizing a photographic dye image is also disclosed.
