Improvements in Rendering Inks Sanitary.
I, EDMUND JAMES MILLS, Professor of Technical Chemistry, 60, John Street,
Glasgow, do hereby declare the nature of this invention to be as follows:-
a
Inks whether employed for writing, printing or similar purposes, frequently cover
large area of the paper or other material to which they are applied. It is therefore
possible to impart a sanitary-that is an antiseptic or disinfecting-property to such
paper or material by impregnating the ink with a suitable sanitary matter. In order to
effect this object I proceed as follows:-
:-
(1.) I incorporate with ordinary printers' ink (or other ink having an oily, greasy
or soapy basis) a mixture of hydric borate, borax and a salicylate soluble in water.
The printers' ink must be prepared first & is a well known article of commerce.
With this the aforesaid mixture is then incorporated in the proportion of five parts
of the mixture to one hundred parts of the ink, other proportions may, however, be
used. After the ink has been printed & dried, the mixture gradually "blooms"
or works its way to the front & back of the letters or figures & can then be easily
attacked & dissolved by cold water.
(2.) Watery inks containing gum, coloring matter, water & sometimes other
constituents, are well known articles of commerce, being commonly used for india
rubber stamps. In one hundred parts of such ink I dissolve two parts of the aforesaid
mixture, which operation is in all cases very easily performed, but other pro-
portions may be effectually used. The compounded ink can then be used in the
ordinary manner.
The proportions I ordinarily use for the "mixture" are borax, to which is added
as much boric acid as it already contains, & to the united weight of these I add one
fortieth part of sodic salicylate, the whole being well ground together. I do not,
however, limit myself exactly to these proportions or only to the sodium compound of
salicylic acid.

Improvements in Rendering Inks Sanitary.
1, EDMUND. JAMES MILLS, Professor of Technical Chemistry, residing at 60, John
Street, Glasgow, 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 :-
Inks, whether employed for writing, printing, or similar purposes, frequently cover
a large area of the paper or other material to which they are applied. It is therefore
possible to impart a sanitary-that is an antiseptic or disinfecting-property to such
paper or material by impregnating the ink with a suitable sanitary matter. In order
to effect this object I proceed as follows:-
(1.) I incorporate with ordinary printers' ink (or other ink having an oily, greasy
or soapy basis) a mixture of hydric borate, borax and a salicylate soluble in water.
The printers' ink must be prepared first & is a well known article of commerce.
With this the aforesaid mixture is then incorporated in the proportion of five parts
of the mixture to one hundred parts of the ink, other proportions may however be
used. After the ink has been printed and dried, the mixture gradually "blooms"
or works its way to the front & back of the letters or figures & can then be easily
attacked & dissolved by cold water.

constituents are well known articles of commerce, being commonly used for india-

fortieth part of sodic salicylate, the whole being well ground together. I do not,
however limit myself exactly to these proportions, or only to the sodium compound
of salicylic acid.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
aim is :-
(1.) The compounding with printers' or other greasy ink of a certain mixture
su uble in water.
(2.) The compounding with watery or embossing ink of a certain mixture soluble
in water.
(3.) The rendering of greasy & watery inks sanitary by means of a certain mixture
soluble in water all substantially as hereinbefore described.
