Abstract
274,627. Johnson, J. Y., (I. G. Farbenindnstrie Akt.-Ges.). June 28, 1926. Lakes.-Colour lakes are made from the condensation products obtained by the interaction of a halogen atom of an aromatic compound halogenated in the nucleus with the amino group of a primary or secondary aromatic amine, which may contain substituent groups, such as sulphonic, carboxylic or hydroxyl groups. The products are fast to water, light and over-printing. In examples, (1) a solution of the sodium salt of the condensation product from 2 : 4-dinitrochlorbenzene and anthranilic acid is mixed. with soda ash, heavy spar and aluminium sulphate, and an orange lake is precipitated by adding barium chloride, and (2) a greenish-yellow lake is similarly obtained from the condensation product of 2 : 4-dinitrochlorbenzene and sulphanilic acid.
