Abstract

1,255,084. Heterocyclic methine dye. EASTMAN KODAK CO. 20 Oct., 1969 [21 Oct., 1968], No. 51344/69. Heading C4P. [Also in Division G2] The dye shown in Fig. 2 above is made by heating together 1 : 3-diethyl-5-[(1-ethyl-naphtho[1 : 2 - d]thiazolin - 2 - ylidene)ethylidene]- 2-methyl-4-oxo-2-imidazolinium iodide, 5-acetanilidomethylene-3-ethylrhodanine, acetic anhydride and triethylamine in pyridine.
