COMPLETE SPECIFICATION.
A Process for the Manufacture of Paint, Frinter's Ink and the like.
I, ADRIAAN STOor, of No. 12, Doelen-Straat, Amsterdam, in the Kingdom of the
Netherlands, Director of the Dordtschen Petroleum Maatschappij, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to the manufacture of paint printer's ink and the like by
the preparation and utilization of an exceptional natural product in the form of a
drying mineral oil, which differs entirely in its composition and characteristics
from ordinary raw mineral oils.
The raw oil which is obtained for instance in large quantities at Grisee in Java
is of syrup like consistency, flowing slowly, and has a specific gravity of *97, it is of
brown colour and found mixed like an emulsion with salt water.
When heated to about 80° Réaumur the greater part of the water can be removed
especially when ordinary salt is added, the emulsion then disappears and the colour
becomes somewhat darker.
The oil thus purified is easily soluble in ether, benzine, benzole, sulphuret of
carbon and chloroform; it is hardly soluble at all in absolute alcohol.
The essential constituent of the oil consists of a substance containing oxygen
and of resinous appearance, which cannot be treated with soap and is mixed with
carburet of hydrogen or hydro-carbons which boil at high temperatures.
By mixing colouring matter with the purified oil, a quick drying and useful
pigment is obtained.
In order to be able to determine the drying period of the pigments with nicety,
oil, which may, if desired, have been cleaned from sand and dirt, is subjected to
partial distillation. This distillation may be carried to any desired extent, and
its object is the removal of those oils which will delay the drying of the pigments.
After the distillation has been carried so far that the oils to be removed are in
the receiver, it is stopped. There is left a more or less consistent varnish-like or
resinous residue in the retort. This residue is treated with volatile solvents, for
instance benzine, petroleum or other hydrocarbons, or with ether, sulphuret of
carbon, chloroform, tetrachloride of carbon, or with any other substance which
will dissolve such residue.
The drying period of the pigment prepared with the oil may be determined by
the choice of the solvent used." For instance if such solvent be very volatile, say
ether or sulphuret of carbon, the pigment will dry quickly. If the pigment is to
dry not so quickly, tetrachloride of carbon, benzole, or other suitable solvent
is used.
The solution of the resinous substance is mixed in the usual manner with the
colouring matter, and the printing, painting or other pigment may be produced
so as to possess definite predetermined drying qualities.

invention and in what manner the same is to be performed I declare that what
I claim is―
A process for the manufacture of paint, printer's ink and the like by the prepara-
tion and utilization of drying mineral oils such as Grisee-oil, in the manufacture
of the said pigments, in which the oil, preferably cleansed from water, sand or
other foreign substances, is distilled to a greater or less extent, and the varnish like
residue is dissolved in more or less volatile solvents, for instance, benzine, petroleum,
or other hydrocarbons, ether, sulphuret of carbon, chloroform, benzole, etc.; with
which solvents the colouring matter is ground or otherwise mixed.
Dated this 2nd day of November 1898.
