| titleOfInvention | Solid particle dispersions of filter dyes for photographic elements |
| abstract | Solid particle dispersions of dyes according to the formula: <IMAGE> (I) wherein D is selected from the group consisting of <IMAGE> <IMAGE> are disclosed as filter dyes for photographic elements. In this formula, R1, R2, and R3 are each independently hydrogen, substituted or unsubstituted alkyl, or substituted or unsubstituted alkoxy. At least one of R1, R2 and R3 is substituted or unsubstituted alkoxy, or two of R1, R2 and R3 together consist of -O-L-O- and form a ring condensed with the phenyl ring to which they are attached wherein L is an alkylene linking group. R4, R5, R6, and R7 are each independently hydrogen, substituted or unsubstituted alkyl, or substituted or unsubstituted aryl. R is a carboxy or sulfonamido substituent, and L1, L2 and L3 are each independently substituted or unsubstituted methine groups. The dyes of the invention are particularly useful as filter dyes for light in the ultraviolet and short blue wavelength regions of the spectrum. |
