LIGHT SENSITIVE COLOR PHOTOGRAPHIC MATERIAL |
| abstract |
New cyan development inhibitor release (DIR) naphthol couplers (I), forming a cyan dye on coupling with the oxidn. prod. of a prim. aromatic colour developer and releasing a mercaptan cpd. with inhibiting action, have the formula: (in which R is an acylamino-substd. phenyl gp. with is not 14C; R' is a heterocyclic, aryl or alkyl gp.). Used in light-sensitive colour photographic materials. Cpds. (I) are non-diffusing and give good image sharpness, low graininess and extended exposure latitude. |
