PROVISIONAL SPECIFICATION.
Improvements in the Preparation of Pigments or Colouring
Compounds.
I, WILLIAM GRIMSHAW, of Lucy Street, City Road, Manchester, in the
County of Lancaster, Drysalter, do hereby declare the nature of this invention
to be as follows:-
My invention consists first in the use and application of glucose or grape and
other sugars or glycerine either separately or combined in combination or
admixture with pigment colours for the purpose of bringing such colours into a
suitable condition for mixing or blending easily and readily with water, or thick and
semi-pasty substances such as starch, flour or gum as used in processes of finishing
and staining with various colours, woven and other fabrics such as paper.
The glucose, or glycerine &c., may be combined with any suitable pigment colour
such for example as the ultramarines and other mineral colours, also vegetable
colours, such as the lakes, and precipitates.
The addition of one or more of the substances named to pigments and lakes
generally serves to assist in the uniform distribution of such pigments upon woven
fabrics, paper and the like.

COMPLETE SPECIFICATION.
Improvements in the Preparation of Pigments or Colouring
Compounds.
I, WILLIAM GRIMSHAW, of Lucy Street, City Road, Manchester, in the
County of Lancaster, Drysalter, 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 :-
My invention consists in the use and application of glucose or grape and other
sugars or glycerine either separately or combined in combination or admixture
with pigment colours for the purpose of bringing such colours into a suitable
condition for mixing or blending easily and readily with water, or thick and semi-
pasty substances such as starch, flour or gum as used in processes of finishing and
staining with various colours, woven and other fabrics such as paper.
The glucose, or glycerine &c., may be combined with any suitable pigment colour
such for example as the ultramarines and other mineral colours, also vegetable
colours, such as the lakes, and precipitates.
In practice I find that good results are obtained by the use of equal quantities of
pigment colour and glucose or its equivalent, with the addition of from 5 to 15 per
cent. of glycerine; or if glucose or its equivalent be used without the addition
of glycerine then I use rather more glucose say five-eighths glucose to three-
eighths pigment colour.
The addition of one or more of the substances named to pigments and lakes
generally serves to assist in the uniform distribution of such pigments upon woven
fabrics, paper and the like; but I wish it to be clearly understood however that I
do not confine myself to the proportions hereinbefore specified as the same may be
varied or modified without departing from the nature or principle of my invention.

page_text: 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
claim is :-
The use and application of glucose or grape sugar and other sugars or glycerine
either separately or combined in combination with pigment colours substantially in
the manner and for the purposes herein specified.
Dated this 17th day of June 1891.
