Improvement in Painting and Colouring Photographs, Prints,
Drawings and the like, and in Solutions therefor.
MILES WILLIAMS Scholes Bridge Wigan Manufacturing Chemist do hereby
declare the nature of this invention to be as follows:-
The invention has for its object the improvement in painting & colouring
photographs prints drawings and the like in fast colours & consists in making
solutions of aniline or other dyes, colours & pigments in glycerine essences,
essential oils, alcohol or naphtha or mixtures of them, free from water & containing
no alkali or alkali salts and the like and without a mordant. I prefer strong clear
solutions of colouring matter made by dissolving aniline or other dyes or pigments
in glycerine, essential oil and alcohol, known in the trade as rectified spirits or
spirit finish free from the addition of water or alkalies & applying the same in any
colour or tint desired with a brush in sufficient quantity to the back of the photo
or print so that it sinks in and penetrates the paper and colours the front or face of
such photo with pleasing effects and without destroying or disfiguring the lights &
shades.
The photographs require no previous preparation, nor does the colours require
gums or a mordant to fix them fast.
These spirit coloured solutions may be varied and used upon either back or front
of picture to paint or colour them or applied to other useful purposes.
Dated this 5th day of February 1896.

I MARGARET WILLIAMS, of 1 Fraser Street, Liverpool, Executrix of MILES
WILLIAMS, of Scholes Bridge, Wigan in the County of Lancaster, Manufacturing
Chemist, 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:-
This invention has for its object the improvement in painting and colouring
photographs, prints, drawings and the like in fast colours and consists in making
solutions of aniline or other dyes colours and pigments in glycerine essences,
essential oils, alcohol or naphtha or mixtures of these practically free from water
aud not containing free alkali or alkaline salt. I prefer strong clear solutions of
colouring matter made by dissolving aniline or other dyes or pigments in glycerine
and essential oil and alcohol of that variety known in the trade as rectified spirits

found the following solution exceedingly useful:-

as a menstruum. To this I add aniline dye dissolved in glycerine as small an
amount of glycerine as practicable or I may add a little glycerine and the aniline
dye direct to the aforesaid menstruum without first dissolving. The menstruum
strongly coloured with the aniline dye as above described is now used as a paint
and is put on with a brush on the back of the photograph or print in the required
quantity, and strength, to produce the effect. If the colouring matter is too strong
more of the menstruum is used to dilute it. The colouring matter sinks in
penetrates the paper and thus colours the print or face of the photograph, the
irregularities conspicuous on the back through defects in laying on not being
observable in the front owing to the blending. In this way pleasing coloured
effects are obtained without destroying or disfiguring the lights and shades. The
ordinary nitrate of silver prints and platinotypes can be used without previous
preparation and the colours do not require a gum or mordant to fix them. These
spirit colour solutions may be varied and used upon either the back or the front of
the picture. It can also be applied to other suitable purposes and used for
colouring transparencies.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be perforined, I declare that what I
claim is :-
1. The improvement in colouring photographs, prints, drawings and the like
which consists in painting them preferably on the back with a suitable aniline or
other chemical colouring matter dissolved in a volatile and practically anhydrous
menstruum with or without glycerine substantially as herein described.
2. The painting materials consisting of a menstruum such as described and a
soluble dye of that class of dyes known as aniline colours capable of dissolving in
the said menstruum substantially as described.
