PROVISIONAL SPECIFICATION.
Process for Producing Imitation Paintings on Glass and Glass Mosaic
Work as Transfer Pictures.
I, RUDOLF BACKHAUS, .Merchant, of No. 14, Nordstrasse, Krefeld, Germany,
do hereby declare the nature of my said invention to be as follows:-
The present invention consists of a process for producing imitation glass painting
or glass mosaic work as transfer pictures, which when transferred to glass have
the appearance of paintings on glass or mosaic work.
In the processes hitherto employed for producing this class of transfer pictures,
lac, varnish or other oily or fatty substances have generally been employed and
owing to the fact that such compositions are subjected to atniospheric influences,
the pictures often become sticky or when dry are liable to crack.
Thus pictures
of this kind when kept in store were liable to stick together or to get cracked and
were consequently valueless.
According to the present invention the paper or other ground material to be
removed when the picture is applied to the glass is first provided with a thin
layer of fluid celluloid or fluid nitrocellulose and the picture then applied to the
backing on this layer in any of the known manners. In order to compensate the
unevenness produced by the application to the backing, of the coloured picture,
the backing is rendered even and smooth by a special process, which forms no part
of the present application and need not be described here.

Process for Producing imitation Paintings on Glass and Glass Mosaic
Work as Transfer Pictures.
I, RUDOLF BACKHAUS, Merchant, of No. 14, Nordstrasse, Krefeld, Germany,
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:―
The present invention consists of a process for producing imitation glass painting
or glass mosaic work as transfer pictures, which when transferred to glass have
the appearance of paintings on glass or mosaic work.
In the processes hitherto employed for producing this class of transfer pictures,
lac, varnish or other oily or fatty substances have generally been employed and

the pictures often become sticky or when dry are liable to crack. Thus pictures
of this kind when. kept in store were liable to stick together or to get cracked and
were consequently valueless.
According to the present invention the paper or other ground material to be
removed when the picture is applied to the glass is first provided with a thin
coating of viscid celluloid or viscid nitrocellulose and the picture then applied to
the coating on this layer in any of the known manners. In order to compensate
the unevenness produced by the application to the backing of the coloured picture
the backing is rendered even and smooth in any suitable manner.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1
A process for producing imitations of glass paintings and mosaic on glass work
in the form of transfer pictures characterised by the step which consists in
covering the paper or other backing with a thin coating of viscid celluloid or
viscid nitro-cellulose and then producing the coloured or other picture thereon
substantially as described.
