HENRY CUNLIFFE, Printer of 12, Stafford Street Barrow-in-Furness in the County
of Lancaster, England and MICHAEL CONDON, Painter of Rawlinson Street, Barrow-
in-Furness in the County of Lancaster aforesaid do hereby declare the nature of this
invention to be as follows:-
The object of our Invention is to Fasten and Glaze every description of Printing
Inks used for Posters, Show Cards and every description of Printing-making the
Ink for a lengthened period perfectly impervious to sun, rain and Billposters' paste,
and is composed of Terebene two parts, Boiled Linseed Oil one part, and a Varnish
made of Canada Balsam and Turpentine one part, but can also be made effectively in
other quantities.

A Substitute for Printers' Varnish for Fastening and Glazing
Printing Inks, Especially for Posters, Show Cards, and General
Use in Printing.
We HENRY CUNLIFFE of 12 Stafford Street, Barrow in Furness in the County of
Lancaster England, Printer, and MICHAEL CONDON of Rawlinson Street Barrow-in-
Furness aforesaid Printer, do hereby declare the nature of this Invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement, that is to say:--
Our said Invention relates to an improved compound for use in combination with
inks and colours in printing, whereby the said inks and colours are rendered more
vivid and lasting than is at present the case. The invention is especially useful in
printing large posters, whether coloured or uncoloured, bills, show cards and for other
similar purposes.
In the case of bills and posters which are exposed to the weather
the inks and colours as at present applied soon fade or run and quickly lose their
appearance under the deteriorating influences of sun, rain and the paste usually em-
ployed to fasten them to the hoardings. The object of our invention is to overcome
these disadvantages by rendering the inks and colours so fast that they will retain
their brilliancy and freshness of appearance for a much greater length of time, thus
rendering their renewal unnecessary except at long intervals. The compound which
we add to or use in conjunction with the said inks and colours is composed of the
following parts the proportions given being those which we have found to be useful,
although such proportions may be largely modified.

We take two parts of the composition known as "painters' terebene one part of
boiled linseed oil and one part of a suitable varnish, the composition of which latter
may vary as its only object is to give a glaze to the ink. These three parts are mixed
together warm until they are thoroughly amalgamated after which the compound is
ready for use.

"
"which we
The ingredient which we have termed
painters terebene varies greatly in
commerce according to the use for which it is intended. We therefore think it
advisable to specify the composition of the so called "painters' terebene
use and which may be made as follows:-
Linseed oil pint.
Oxide of lead 2 drams.
These are boiled together for an hour, keeping them constantly stirred.
drops of acetic acid are then added.
A few
Another and as we at present think a preferable composition of "painters terebene
is as follows:
Linseed oil pint.
Turnentine 1 nint

page_text: These should be dissolved together at a gentle heat until thoroughly amalgamated.
A useful composition of varnish or glazing agent for adding to the "painters' tere-
bene" and boiled linseed oil is as follows:-
Pale hard copal 2 lbs.
Boiled linseed oil 1 pint.
Spirit of turpentine 3 pints.
These are dissolved together and form a very suitable varnish but other compositions
of varnish might be employed with equally useful results.
In the compositions of "painters' terebene" herein before set forth it will be evident
to chemists that the linseed oil and turpentine act chiefly as vehicles, the important
fixing agent being the oxide or acetate of lead. The proportions of the other
ingredients might therefore be varied or the said oxide or acetate might be added
per se to the varnish and boiled linseed oil, but so long as an oxide or acetate or other
compound or derivative of lead is used the object of our invention so far as the fixing
of the ink is concerned would be attained.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed we declare that what we claim is :-
:-
(1) The improved composition for adding to or using in combination with printers
inks and colours so as to fix and glaze the same and render them more capable of
resisting the deteriorating effects of the elements and of other destructive agents
substantially as hereinbefore described and set forth.
(2) An improved composition for use in conjunction with printers inks and colours
and consisting of "painters terebene" boiled linseed oil and varnish, amalgamated
in the proportions set forth or in suitable proportions, substantially as described.
(3) An improved fixing and glazing composition for use in conjunction with
printers inks and colours and containing an acetate or oxide or other compound or
derivative of lead as a fixing agent, such acetate or oxide or other compound or
derivative of lead being either a component part of the herein described "painters'
terebene "
or introduced separately as herein set forth.
