    Abstract: 1,162,808. Benzoates of basic dyes; inks. BADISCHE ANILIN- & SODA-FABRIK A.G. 29 Dec., 1966 [30 Dec., 1965], No. 58121/66. Headings C4A and C4P. The invention comprises benzoates of basic dyes of the diphenyl or triphenyl methane, xanthene, monoxazine and heterocyclic methine series, wherein the benzoate radical is derived from a benzoic acid of the formula wherein X represents H, halogen, amino, OH, OCH 3 , alkyl, C 6 H 5 CO, CH 3 CO or an esterified carboxylic group and Y represents H, Cl, amino or OH; which are soluble in alcohols but practically insoluble in water. They may be obtained by reacting a salt of a basic dye with a salt of a benzoic acid of the above formula or by reacting a free dye base with a free benzoic acid of the above formula. Examples are given for the production of the compounds. Printing inks and ball point pen inks are obtained from the above dye salts. In Example (7) a flexographic printing ink is obtained by dissolving a dye in alcohol, ethyl cellosolve and shellac, and (8), (9) a glycol printing ink and a ball point pen ink are obtained by dissolving dyes in a phthalic acid hexanetriol ester and diethylene glycol.

    Abstract: The invention comprises nitrobenzoates of basic dyes of the diphenylmethane, triphenylmethane, xanthene or oxazine series which are soluble in alcohols but practically insoluble in water. They are obtained by adding nitrobenzoic acid or a salt thereof during or after the preparation of a composition containing a commercial basic dye of the said series. Examples are given for the production of the salts. The products are suitable for the production of printing inks and examples are given for the production of such inks using various dyes and a resin solution of 23 parts shellac, 70 parts alcohol and 7 parts ethyl glycol.
