page_text: I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby' declare the nature of this Invention a communication to me
from abroad by Dr. Armand Müller-Jacobs of the City, County and State of New
York United States of America, Chemist, through his Agents Wirth and Company
of Frankfort-on-Main in the Empire of Germany, to be as follows:
This Invention relates to the manufacture of coloring matters or dyes, and a
vehicle for the same.
The Invention consists first in the manufacture of a new coloring matter in the
form of a dry powder and composed of the resinate of a metal or of an alkaline
earth and a soluble coloring matter or dye.
In carrying out the Invention the resinate is first prepared in the following
manner; A sufficient quantity of a caustic alkali, such as hydrate of potash, soda,
ammonia, or organic bases (ethylamine etc.) is dissolved and mixed at boiling
heat with as much colophony or other resin as the same can absorb whereby a
resinate of the alkali is produced. This resinate is mixed to the point of saturation
with sulphate of zinc or aluminium, or any other salt of a metal or alkaline earth
and the resulting precipitate washed out and dried.. The precipitate is a fine
powder consisting of resinate of the zinc, aluminium, or other metal, or alkaline
earth, that has been employed. These resinates have the property of uniting with
any soluble color or dye such as aniline-colors, azo-colors, and other colors obtained
from coal-tar, and also with vegetable-dyes and wood-extracts. The coloring
matters thus produced by the combination of the resinates of metals or alkaline
earths with soluble coloring matters and dyes are reduced to the form of a powder,
possess considerable body, and have the advantage of being soluble in benzine,
ether, turpentine, oils, etc, which has not been possible with the colors or dyes
heretofore. They possess a brilliant lustre and can be applied to many purposes
[Pring C/1

page_text: in the arts, such as for printing on textile fabrics and wall-papers, and as
varnishes, lithographic colors, etc. As many different colors and tints can thus be
produced, as there are different shades of colors and dyes, they uniting in all cases
with the resinate of the metals or alkaline earths, which latter form the vehicle by
which they are made soluble in benzine and other solvents mentioned.
The Invention relates secondly to the manufacture of liquid coloring matters
applicable for use as paints, and to a vehicle for coloring matters or dyes. The
coloring matter is composed of the resinate of an alkali, benzine or other similar
solvent and a soluble coloring matter or dye.
A sufficient quantity of caustic alkali is dissolved and mixed at boiling heat
with as much colophony or other resinous gums as the same can absorb. The
resinate of the alkali thus obtained is drawn off, strained, and allowed to cool.
From ten to thirty parts of this resinate are then mixed with from ninety to
seventy parts of benzine, turpentine, oil-varnish, alcohol, or any other suitable
solvent, to which any soluble coloring matter or dye such as aniline-colors, azo-
colors, or vegetable dyes are added. The resinate of the alkali and the benzine or
other solvents form a vehicle for the coloring matter or dye, the resinate imparting
body to the coloring matter or dye and rendering it soluble in the solvents
mentioned. Paints of very bright colors are thus obtained for application in the
arts.

I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this invention (a communication to me
from abroad by Dr. Armand Müller-Jacobs of the City, County and State of New
York, United States of America, Chemist, through his Agents Wirth and Company
of Frankfort on the Main, in the Empire of Germany), and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to the manufacture of a colouring composition, in the
form of a powder, and soluble in benzole, chloroform, ether, bi-sulphide of carbon,

page_text: and oils; and the invention consists of a colouring composition, composed of the
resinate of a metal, and a colour or dye.
In carrying out the invention I proceed as follows:-I prepare a neutral resin
soap by any of the well known processes, dissolve this soap in water and add to
this solution, a solution of sulphate of zinc or alumina or any other salt of a
metal, forming a precipitate, which precipitate is then washed and dried. This
precipitate is a fine powder, consisting of the resinate of zinc, alumina, or other
metal, whichever has been employed.
•
This resinate can be coloured by either adding a colour solution to the solution
of soap or to the solution of the metal salt before precipitation, or by passing an
aqueous or alcoholic solution of colour through the dry powder and then drying
again.
The colour thus added will be, up to the saturation point, chemically combined
with the resinate; any surplus colour can be washed out. The colours most suitable
for the purposes of this invention are aniline colors.
The coloured resinates thus obtained are soluble in benzole, chloroform, ether,
bi-sulphide of carbon, and oils, also in benzine, and oil varnishes, and can be used
for many purposes in the arts, for coloured varnishes, printing inks, for dyeing
textile fabrics etc, also as pigments for printing on textile fabrics, paper, etc.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. The processes of producing coloring compositions, soluble in benzole, chloro-
form, ether, bisulphide of carbon and oils, substantially as described.
2. Colouring compositions, soluble in benzole, chloroform, ether, bi-sulphide of
carbon, and oils, composed of the resinate of a metal, and colour or dye, sub-
stantially as described.
