page_text: This Specification was, upon the 27th day of December 1889, Amended under
Sections 18 to 21 of the Patents, Designs, and Trade Marks Act, 1883.
I, PETER JENSEN Fel. Inst. P.A. of 33 Chancery Lane in the County of
Middlesex do hereby declare the nature of this invention (a communication
to me from abroad by the "Actiengesellschaft für Anilinfabrikation" of Berlin
Germany Aniline Manufacturers) to be as follows:-
It is stated in the specification of Patent N° 44154 that in the production of the
azo-color obtained by the combination of salts of tetrazo-diphenyle with naphtionic-
acid and known in the market under the name of Congo, the mixture of the two
components must stand for some while viz. 12 hours.
This statement is based upon the observation that by the action of one molecule
of the tetrazo-compound upon two molecules of naphtionate of soda the coloring
matter congo is not formed instanteously but that at first an intermediate product
of one molecule of tetrazo-diphenyle with one molecule of naphtionic-acid is formed
which acts upon the second molecule of naphtionic-acid only after some time.
Analagous to the naphtionic-acid act the other amines and amido-acids mentioned
in the patent specification N° 441584.
At first always one molecule of tetrazo-diphenyle with one molecule of an amine
or an amido-acid form an intermediate product which can afterwards be combined
with a second molecule of an amine or phenole or their sulpho-acids. In which
manner the same amine or amido-acid may be used for that combination is already
described in the patent specification N° 441584.
If however one molecule of another amine or amido-acid or phenole or phenole-
sulpho-acid act upon the intermediate products mixed Azo-colours are obtained.
They may be produced by first combining the tetrazo-compound with the
phenoles as well as by acting afterwards upon the amines. The characteristic
property of all these latter is the facility in which they dye cotton from an
alcaline bath without the use of a mordant. In all cases the salts of tetrazo-
diphenyle may be replaced by salts of tetrazo-ditolyle.

page_text: a solution containing 12,2 Kg of naphtionate of soda and 32 Kg of acetate of soda
in 900 litres of water whereby the above mentioned intermediate product formis
itself as a brown precipitate which is insoluble in alcalines.
If, now, a solution of 12,2 Kg of ẞ naphtylamine-sulphonate of soda in
100 litres of water is poured out upon that intermediate product, and if the
mixture is stirred for a longer period an Azo-colour is formed which is soluble
in alcalines and which dyes shades similar to Congo but somewhat yellower. This
reaction can also be reversed in-as-much as the tetrazo-diphenyle is at first com-
bined with the ẞ naphtylamine-sulpho-acid and afterwards the intermediate
product thus obtained is made to act upon a naphtylamine-sulpho-acid.
Coloring matter from Benizdine, a naphtylamine-sulpho-acid, and a naphtole-
sulpho-acid.
The above mentioned intermediate products can also be combined to new mixed
Azo-colours with phenols respectively naphtoles and their sulpho-acids. If in
example I Process I the quoted quantity of ẞ naphtylamine sulphonate of soda is
replaced by 12,3 Kg of a naphtole-sulphonate of soda a colour is obtained which
dyes cotton a violet shade. The same colour, as is already stated above, may be
obtained by first combining the tetrazo-diphenyle with a naphtole-sulpho-acid as
well as by acting afterwards with the intermediate product thus obtained upon
naphtylamine-sulpho-acid.
a
EXAMPLE IV.
Coloring matters from diamido ditolyle a naphtylamine-sulpho-acid and
ẞ naphtylamine-sulpho-acid.
If in example I the Benzidine is replaced by the equivalent quantity of diamido
ditolyle a colour is obtained which is very to Congo.
This invention then comprises the production of red and violet Azo-colours of
properties exactly like those described in patent specification Nº 44154 especially
as far as regards their property of dyeing cotton from an alcaline bath without the
use of a mordant, and which are obtained by first combining one molecule of a salt
of tetrazo-diphenyle or tetrazo-ditolyle with one molecule of naphtylamine or
naphtylamine sulpho acid, and by acting afterwards with the products thus
obtained upon amines or phenoles and their sulpho acids. It may be stated here
that in the latter case mixed Azo-colours can be obtained also in a reverse way by
first combining the tetrazo-compound with the phenoles or their sulpho-acids and
by acting afterwards upon the amines or their sulpho acids.
Dated this 12th day of December 1885.

page_text: Process for the Production of Mixed Azo Colours.
I, PETER JENSEN Fel. Inst. P.A. formerly of 33, but now of 77, Chancery Lane
in the County of Middlesex do hereby declare the nature of this invention
(a communication to me from abroad by the "Actiengesellschaft für Anilin-
fabrikation" of Berlin, Germany, Aniline Manufacturers) and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
It is stated in the specification of patent N° 4415% that in the production of
the azo colour obtained by the combination of salts of tetrazodiphenyle with
naphtionic acid and known in the market under the name of Congo, the mixture
of the two components must stand for some while viz. 12 hours.
This statement is based upon the observation that by the action of one molecule
of the tetrazo compound upon two molecules of naphtionate of soda the colouring
mattor Congo is not formed instantaneously but that at first an intermediate
product of one molecule of tetrazo-diphenyle with one molecule of naphtionic acid
is formed which acts upon the second molecule of naphtionic acid only after some
time. Analogous to the naphtionic acid act the other amines and amido acids
mentioned in the patent specification Nº 4415.
At first always one molecule of tetrazo-diphenyle with one molecule of an amine
or an amido acid form an intermediate product which can afterwards be combined
with a second molecule of an amine or phenole or their sulpho acids. In which
manner the same amine or amido acid may be used for that combination is already
described in the patent specification N° 4415. If however one molecule of another
amine or amido acid or phenole or phenole-sulpho acid act upon the intermediate
products, mixed azo colours are obtained.
They The mixed azo color made from amines and phenoles may also be produced by
first combining the tetrazo compound with the phenoles as well as and by acting
afterwards upon the amines. The characteristic property of all these latter colors is
the facility in which they dye cotton from an alkaline bath without the use of a
mordant.
In all cases the salts of tetrazo-diphenyle may be replaced by salts of tetrazo-
ditolyle.

If now a solution of 12.2 Kg. of B-naphtylamine-sulphonate of soda in 100 litres
of water is poured out upon that intermediate product and if the mixture is stirred
for a longer period an azo colour is formed which is soluble in alkalines and which
dyes shades similar to Congo but somewhat yellower. This reaction can also
be reversed in as much as the tetrazo-diphenyle is at first combined with
B-naphtylamine-sulpho acid and afterwards the intermediate product thus obtained
is made to act upon a-naphtylamine-sulpho acid.
The above mentioned intermediate products can also be combined to new mixed
azo colours with phenoles respectively naphtoles and their sulpho acids. If in
example I, process I, the quoted quantity of B-naphtylamine sulphonate of soda is
replaced by 12.3 Kg. of a-naphtole-sulphonate of soda, in the presence of an alkali a
colour is obtained which dyes cotton a violet shade. The same colour as is already
stated above, may be obtained as well by first combining the tetrazo-diphenyle with
a-naphtole-sulpho acid and by afterwards acting afterwards with the intermediate
product thus obtained upon a-naphtylamine-sulpho acid.
Colouring matters from diamido - ditolyle- a - naphtylamine-sulpho acid and
ẞnaphtylamine-sulpho acid.
If in example I the benzidine is replaced by the equivalent quantity of diamido-
ditolyle a colour is obtained which is very similar to Congo.
This invention then comprises the production of red and violet azo colours of
properties exactly like those described in patent N° 44154 especially as far as
regards their property of dyeing cotton from an alkaline bath without the use of
a mordant and which are obtained by first combining one molecule of a salt
of tetrazo-diphenyl or tetrazo-ditolyl with one molecule of naphtylamine or
naphtylamine-sulpho acid, and by acting afterwards with combining the products thus
obtained upon with amines or phenoles and or their sulpho acids. It may be stated
here that in the latter case mixed azo colours can be obtained also in a reverted way
by first combining the tetrazo-compound with the phenoles or their sulpho acids
and by acting afterwards upon the amines or their sulpho acids.
Having now particularly described and ascertained the nature of said invention
and in what manner same is to be performed I declare that what I claim is
The process for the production of red and violet azo colours of properties like
those described in patent specification No 44154 especially as far as regards their
property of dyeing cotton from an alkaline bath without the use of a mordant, and
which are obtained by first combining one molecule of a salt of tetrazo-diphenyl

with the phenoles or their sulpho-acids and by acting afterwards upon combining
the product obtained with the amines or their sulpho-acids substantially as described.
