Process for Increasing the Suppleness or Pliability of Paper.
I, OSCAR TIETZE, Managing Director, of Ratingen, near Düsseldorf, Germany,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object, to render hard paper pliable and consequently
more suitable for concert- or theatre programmies, and for other purposes.
For this purpose I saponify a comparatively large quantity of castor-oil, either
alone or in mixture with other oils or fats, and a comparatively smaller quantity of
resin, and dilute the product with water.
I then dip the paper into the solution or emulsion thus obtained, or I apply the
the latter to the paper by means of a brush, and subsequently dry the paper.
Paper treated in this manner is just as supple as if it had been treated with oils
or fats alone, but owing to the complete saponification of the castor-oil and of the
resin, it is not fatty.
The admixture of resinous soap to soap derived from oil or fat has for its object
the prevention of excessive suppleness of the paper.

Process for Increasing the Suppleness or Pliability of Paper.
I, OSCAR TIETZE, Managing Director, of Ratingen, near Düsseldorf, 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 :-
This invention has for its object, to render hard paper pliable and consequently
more suitable for concert or theatre programmes, and for other purposes where a.
certain degree of pliability without loss of strength is required.
For this purpose I saponify a comparatively large quantity of castor-oil, either
alone or in mixture with other oils or fats, and a comparatively smaller quantity of
resin, and dilute the product with water.
I then dip the paper into the solution or emulsion thus obtained, or I apply the
latter to the paper by means of a brush, and subsequently dry the paper.
Paper treated in this manner is just as supple as if it had been treated with oils
or fats alone, but, owing to the complete saponification of the castor-oil and of the
resin, it is not fatty.
The admixture of resinous soap to soap derived from oil or fat has for its object
the prevention of excessive suppleness of the paper; consequently the proportions
may be varied and will depend on the desired effect.

page_text: For instance, to produce a moderately pliable paper suitable for theatre
programmes, I take for 100 kilos. of paper 1 kilogramme of castor oil, 4 kilos. of
palm oil, and 1 kilogramme of resin, saponify the whole with caustic soda in the
well-known manner, and dilute the soap thus obtained, with 25 litres of water by
means of an agitator and moderate heat (about 25° Centigrade), nutil a uniform
emulsion is produced.
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 process for increasing the suppleness or pliability of paper, which consists
in impregnating it with a liquid consisting of an aqueous solution or emulsion of
soap derived from oil or fat and from resin, substantially as described.
