I, OLIVER IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the County
of London, Chartered Patent Agent, do hereby declare the nature of this invention to
be as follows:-
My foreign correspondents have found that amidobenzylamine and its derivatives
alkylised in the side chain, such as amidobenzyldiethylamine and amidobenzyl-
diethylmethylammonium, may be employed (in the same way as the aromatic
amidoammonium bases, for instance, amidophenyltrimethylammonium) for the
production of disazocolouring matters, which dye vegetable and animal fibre in mixed
goods simultaneously in an acid bath. As is the case with the aromatic amido-
ammonium bases, colouring matters having the said properties are likewise obtained
from benzylamine derivatives in form of both primary and secondary disazo-bodies.
EXAMPLE 1.
100 parts by weight of the double chloride of zinc and p-amidobenzylethylamine,
are dissolved in 60 parts by weight of concentrated hydrochloric acid to which are
added 18 parts by weight of nitrite. The solution is run into an alkaline solution of
55 parts by weight of benzineazoresorcinol. After several hours standing the solution
is boiled and filtered. By adding hydrochloric acid the colouring matter is
transformed into a salt soluble in water.
EXAMPLE 2.
100 parts by weight of the double chloride of zinc are diazotised as in the preceding
example, then combined with 37 parts by weight of a-naphthylamine to which are
added 150 parts by weight of acetate of sodium and 70 parts by weight of hydrochloric
acid. After several hours standing the solution is again diazotised with 200 parts by
weight of hydrochloric acid and the corresponding quantity of nitrite, then combined
with 37 parts by weight of B-naphthol in an alkaline solution. The colouring matter
is separated as in the preceding example and made soluble in water.

Manufacture of Basic Disazocolouring Matters.
I, OLIVER IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the County
of London, Chartered Patent Agent, do hereby declare the nature of this invention
(which has been communicated to me from abroad by The Farbwerke vormals:
Meister Lucius and Brüning, of Hoechst a/Main, in the Empire of Germany,
Chemical Manufacturers) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My foreign correspondents have found that amidobenzlamine and its derivatives
alkylised in the side chain, such as p-amidobenzyldiethylamine and p-amido-
benzyldiethylmethylammonium, may be employed (in the same way as the aromatic
amido-ammonium bases, for instance, amidophenyltrimethylammonium) for the
production of disazo-colouring matters, which dye vegetable and animal fibre in mixed
goods simultaneously in an acid bath. As is the case with the aromatic amido-
ammonium bases, colouring matters having the said properties are likewise obtained
from benzyl-amine derivatives in forms of both primary and secondary disazo-bodies.
EXAMPLE 1.
100 parts by weight of the double salt of chloride of zinc and of the hydrochloric
salt of para-anidobenzyldiethylamine are dissolved in 60 parts by weight of concen-
trated hydrochloric acid diluted with water and then with a solution of 18 parts by
weight of nitrite. The solution is run into an alkaline solution of 55 parts by weight
of benzeneazoresorcinol. After several hours standing, the solution is boiled and
the colouring matter is filtered. By adding hydrochloric acid to the colouring matter
it is transformed into a salt soluble in water.
EXAMPLE 2.
100 parts by weight of the double salt employed in Example 1 are diazotised as in 1,
then combined with 37 parts by weight of a-naphthylamine to which are added 150 parts
by weight of acetate of sodium and 70 parts by weight of hydrochloric acid. After
several hours standing the solution is again diazotised with 200 parts by weight of
hydrochloric acid and the requisite quantity of nitrite, then combined with 37 parts
by weight of B-naphthol in an alkaline solution. The colouring matter is separated
as in the preceding example and made soluble in water.
No essential change takes place in the method if, instead of amidodiethyl-
benzylamine, as described in the above examples, other amidobenzylamine derivatives
alkylised in the side chain be used.
The following combinations may serve as examples of dye-stuffs obtained by this
method.

Having now particularly described and ascertained the nature of this invention
d in what manner the same is to be performed, I declare that what I
aim is
1. The herein described manufacture of basic disazo dye-stuffs by diazotising
erivatives of p-amidobenzylamine, alkylised in the side chain, and allowing them to
t upon azo-dyestuffs capable of combining, or by diazotising amido azo dyestuffs
oduced from the said amido benzylamine derivatives and primary amines and
lowing them to act upon phenols and amines.
2. The dyestuffs manufactured as above set forth.
