| titleOfInvention | Compounds and composition useful as dot promoting agents |
| abstract | Disclosed are novel compounds of the formula:n wherein: nX=-NR₅R₆, or -OR₇; n R₁ and R₂ are independently hydrogen, substituted or unsubstituted alkyl, haloalkyl, hydroxyalkyl, alkoxyalkyl, alkylaminoalkyl or arylalkyl having up to 18 carbons; cycloalkyl; phenyl or naphthyl; alkylphenyl, cyanophenyl, halophenyl or alkoxyphenyl substituents. n R₃ is hydrogen, benzyl, alkoxybenzyl, halobenzyl or alkylbenzyl, provided that if neither R₁ nor R₂ is hydrogen, then R₃ is hydrogen. n R₄ is a divalent aromatic group which is substituted or unsubstituted. n R₅, R₆, and R₇ are independently hydrogen, alkyl, hydroxyalkyl, haloalkyl, alkoxyalkyl, alkylaminoalkyl, acylaminoalkyl, aminoalkyl or phenylalkyl having up to 12 carbons; a cycloalkyl substituent; phenyl or naphthyl; an alkylphenyl, cyanophenyl, halophenyl or alkoxyphenyl substituent. n Furthermore, either R₁ and R₃ or R₁ and R₂ can be linked to form a heterocyclic ring system containing 3-10 atoms. n Additionally, R₅ and R₆ can be linked to form a heterocyclic ring system containing 3-10 atoms. n Y is an oxygen or sulfur atom. If Y is sulfur then n=1, if Y is oxygen then n=0 or 1. n These compounds are useful as high-quality dot promoting agents in negative-working photographic systems. n Disclosed as well are radiation-sensitive compositions and elements containing such dot promoting agents in combination with silver halide grains. These exposed compositions and elements when processed in a developer containing a dihydroxybenzene developing agent, a substituted benzotriazole, a sulfite preservative and an amine compound provide a method for the production of halftone dots possessing high image quality. |
