Filter dyes for photographic elements |
| abstract |
Solid particle dispersions of dyes according to the formula:n n are disclosed as filter dyes for photographic elements. n In this formula, m and n are each independently 0 or 1. n R₁ and R₂ are each independently substituted or unsubstituted alkyl or substituted or unsubstituted aryl, or together with R₃ and R₄ form a heterocyclic ring. n R₃ and R₄ are each H or together with R₁ and R₂ form a heterocyclic ring. n A is a ketomethylene residue. n X represents a carboxyphenyl or sulfonamidophenyl, or a carboxy or sulfonamido substituent that is appended to an aryl ring that is part of A. |
