Abstract

536,939. Hydroxy-acidylamino-naphthalene derivatives. KODAK, Ltd. (Eastman Kodak Co.). Aug. 24, 1939, Nos. 24322/39, and 2705/41, divided out of 538,914. [Class 2 (iii)] [Also in Group XX] A colour development coupler for use in conjunction with an aromatic development agent has the general formulawhere Y and Z are monovalent organic substituents such as alkyl, aryl, or aralkyl, not containing solubilizing groups such as alcoholic hydroxyl or sulphonic or carboxylic acid or their derivatives. Either or both rings may be substituted by halogen atoms, which may be introduced after formation of the amide. The following examples of derivatives of 5 amino-1 naphthol are given : N-benzyl:N-α-naphthoyl ; N-benzyl:N-#-naphthoyl; 2:4-dichloro-N-benzyl: N-x-N-x-naphthoyl ; 2:4-dichloro-N-benzyl: N- α-naphthoyl: N-γ-phenyl-n-propyl:N-n-valeryl ; N-γ-phenyl-n-propyl:N-p-sec-amylbenzoyl ; N- α-phenyl-n-propyl: N-benzoyl and N-γ-phenyln-propyl: N.#. - naphthoyl. Specifications 458,664, 499,185, 500,611, 500,718, 500,826, 503,752, 503,814, 503,817, 503,818, 503,820, 503,821, 503,939, 503,940, 524,154, 524,554. 524.555, 530,685, [all in Group XX], and 531,312 are referred to.
