An Improved Method of and Process for Colouring and Ornamenting
Paper and like Material.
We, SAMUEL MUSGRAVE, of 22, Mansell Road, Acton, Chemist, HARRY
MUSGRAVE, of 5, Shalimar Terrace, Acton, Cashier, JOHN TOLHURST MUSGRAVE,
of 27, Pall Mall, S.W., Secretary to Public Company, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a novel method of, and process for, obtaining upon
the surface of paper or other suitable material, various effects in iridescent
colours, of great beauty, and particularly well adapted for wall-papers, show cards,
advertizing placards, and notices, and the like.
In order to put the invention in operation we use a mixture consisting (1) of a
solution containing tannic acid, say for example an infusion of one ounce of
powdered galls in four ounces of water, and (2) an emulsion of sea moss (preferably
Irish moss) in water, say, for example, one ounce of sea moss to ten ounces of
water. We do not however confine ourselves to these proportions, which may
be varied more or less as may be found advisable to suit different circumstances.
In order that the surface of the material, such as paper, upon which the
various iridescent colours are to be produced, may itself be of a suitable colour
and material to produce the best iridescent effects, we add to the mixture described
a suitable colouring material, such for instance as a solution or infusion of
sulphate of cobalt, logwood, saffron, sulphate of nickel, china blue, or other suit-
able material which may be varied almost infinitely so long as the substance used
is one which does not have any objectionable action upon the other materials
and the process used.
The strength and proportions of the colouring materials so added to the mix-
ture first described, may also be varied more or less as desired.
The compound mixture described having been coated by hand or by other suit-
able means, upon the surface of the paper or other material, the latter is passed,
either in sheets or in long lengths, through a chamber containing ammonia in
vapour, which has the effect of at once acting upon the mixture of tannin and
sea moss, so as to produce the beautiful iridescent effect described.
The sheets after passing through the ammonia are withdrawn from the chamber
and are quickly dried, and if desired they may be subsequently polished by hand
or in any convenient way.
Upon the sheets any desired ornamental or other designs or inscriptions may
be added in inks or pigments of any suitable colours or character, the designs so
5 produced not showing upon their surface the iridescent colours exhibited upon the
remainder of the paper.
By this invention wall papers, or other paper or other materials can be quickly
and cheaply ornamented with designs of great beauty and extremely effective.

We, SAMUEL MUSGRAVE, of 22, Mansell Road, Acton, Chemist, HARRY
MUSGRAVE, of 5, Shalimar Terrace, Acton, Cashier, JOHN TOLHURST MUSGRAVE,
of 27, Pall Mall, S.W., Secretary to Public Company, 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, that 18
to say:-
The object of our invention is to produce upon the surface of paper or other
suitable material, various effects in iridescent colours, of great beauty, and
particularly well adapted for wall-papers, show cards, advertizing placards and
notices, and the like.
In order to put our invention in operation, we use a mixture consisting
(1). Of a solution containing tannic acid, say for example, an infusion of one
ounce of powdered galls in four ounces of water, and
(2). An emulsion of sea moss (preferably Irish moss) in water, say, for example,
one ounce of sea moss to ten ounces of water. These proportions need not, how-
ever, be strictly adhered to, and may be varied to suit different circumstances.
In order that the surface of the material, such as paper, upon which the
iridescent colours are to be produced, may itself be of a suitable colour
and material to produce the best iridescent effects, we add to the mixture described
a suitable colouring material, such for instance as a solution or infusion of
sulphate of cobalt, logwood, saffron, sulphate of nickel, china blue, or other suit-
able material, which may be varied almost infinitely so long as the substance used
is one which does not have any objectionable action upon the other materials
used. The strength and proportions of the colouring materials so added to the
mixture described may also be varied. The paper or other material having been
coated, either completely or in parts, by hand or otherwise, with the compound
mixture described, the former is passed through a chamber containing ammonia
in vapour, which has the effect of at once acting upon the mixture with which
it is coated so as to produce the beautiful iridescent effect described.
The paper or other material (which may be in sheets or lengths) after passing
through the ammonia is withdrawn from the chamber and quickly dried, and may
be subsequently polished in any desired way.
The paper or other material may be ornamented by adding designs or inscrip-
tions in inks or pigments of suitable colours and character, these designs or
inscriptions not showing upon their surfaces the iridescent colours exhibited upon
the remainder of the paper. Where the paper or other material is found to be
too absorbent, it may be first covered with a coating of paste of ordinary flour.
By means of our invention many beautiful effects can be produced. Wall papers
of the cheapest description can be greatly improved in appearance and value. A
pattern or design can be drawn upon the paper or other material, and such pattern
or design only coated with the mixture. In this case the pattern or design will
be rendered iridescent, whilst the rest of the paper will be left in its original state.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The process of producing iridescent coloured effects upon paper or other
material, which consists in coating such paper or other material with a
com-
4

the action of ammonia vapour, and afterwards drying it, substantially as described.
2. For the purpose of producing the best iridescent effects upon the surface
of the paper or other material, the addition to the mixture with which the paper
is to be coated of a colouring material, such as a more or less strong solution or
infusion of sulphate of cobalt, logwood, saffron, sulphate of nickel, or china blue,
substantially as described.
