Abstract: A compound of the formula (1) (1) in which X and X' stand for an optionally functionally modified carboxy or sulfo group and wherein the naphthalene nuclei may carry further non- chromophoric substituents and a process for their preparation. These compounds are valuable optical brighteners and can be applied by the methods known in this field.

Abstract: Novel beta-naphthyl derivs. contg. sulpho gps. are of formula (I):- (where R = H, a colourless cation or lower alkyl; M=H or a colourless cation; A= opt. substd. phenyl, diphenyl, alpha- or beta- naphthyl), and more specifically of formula (II):- (where R=H or lower alkyl; M = alkali metal or ammonium cation). Used as optical for natural and synthetic materials such as wool, silk, leather, cotton, paper, wood, rubbers, gutta percha, polyamides, polyurethanes, etc. but pref. for regenerated cellulose fibres, wool and synthetic polyamides. Also for use in detergent comps. Effective amts. are 0.01-2 (0.02-0.1)%.

Abstract: Compounds of the general formula I in which X represents a trifluoromethyl group or a fluorine atom, n is 1 or 2, Z is an oxygen atom or a NR grouping, in which R is hydrogen or an optionally substituted alkyl group, the benzo rings optionally containing further nonchromophoric substituents. These compounds may be prepared by reacting the dichloride of 1,4-naphthalene-dicarboxylic acid with 2 mols of an o-aminophenol or of an o-nitroaniline and by subsequently cyclizing the acylamino compound obtained. The products are suitable as optical brighteners.
