IMPROVEMENTS IN THE PRODUCTION OF CERTAIN COLORING MATTERS APPLICABLE TO DYEING AND PRINTING
Year: 1883

page_text: LETTERS PATENT to Thomas Holliday of the firm of Read Holliday and
Sons of Huddersfield in the County of York but at present rosiding at
Houlme, near Malaunay, Seine Inferieure in the Republic of Franco. Manu-
facturing Chemist. for an Invention of IMPROVEMENTS IN THE PRODUCTION
OF CERTAIN COLORING MATTERS APPLICABLE TO DYEING AND PRINTING.
PROVISIONAL SPECIFICATION left by the said Thomas Holliday at the
Office of the Commissioners of Patents on the 16th August 1883.
THOMAS HOLLIDAY of the firm of Read Holliday and Sons of Huddersfield, in
the County of York, but at present residing at Houlmo near Malaunay, Seine
Inferieure, in the Republic of France, Manufacturing Chemist. "IMPROVEMENTS
IN THE PRODUCTION OF CERTAIN COLORING MATTERS APPLICABLE TO DYEING AND
PRINTING."
This invention relates to the employment of Fluorols in a somewhat similar
manner to the Napthols and Fluorylamines in a similar manner to tho Napthyl-
amines in the manufacture of azo colours.
In carrying out my improvements I combine the following diazo compounds
with Fluorols or their sulpho acids. tho diazo compounds of benzole, toluole, xylole,
cinnole, napthols, fluorols; the sulpho acids of those diazo compounds, diazo-
amido-azo compounds of benzole, toluole, xylole. The sulpho acids of these diazo
compounds. The process is similar to the one now in use for the manufacture of
azo colours. One of the diazo compounds or one of their sulpho acids in solution
in water being mixed at a low temperaturo with an alkaline solution of one of the
fluorols or a sulpho acid of one of the fluorols.
Napthols and their sulpho acids may be combined with diazo fluorols and their
sulpho acids by mixing alkaline solutions of each of them with a solution of a diazo
fluorol or a sulpho acid of a diazo fluorol at a low temperature.

page_text: The colouring matters thus produced may be precipitated by salt or an acid such
as Muriatic acid and may be used in a similar manner as the azo coloring produced
with napthol or with, Napthylamine.
The colours formed which do not contain the Sulphuryl group being almost
insoluble in water may be formed on textile fibro by impregnating the fibre with
an aqueous solution of fluorole and a solution of one of the diazo compounds,
or by impregnating the fibre with an aqueous solution of napthol and a diazo
compound of fluorol taking care in each instance to have enough alkali present
to dovelope the colour

by the said Thomas Holliday in the Patent Office on the 15th February
1884.

Having thus described the nature of my said invention and means adapted for
carrying the same into practical effect I would have it understood that what I
claim is
•
The production of certain coloring matters applicable for dyeing and printing
either as separate bodies or in the presence of textile fibre substantially as
described
In witness whereof I the said Thomas Holliday have hereunto set my band and
seal this thirteenth day of February in the year of our Lord One thousand eight
