composition andthe process'of making same, and more partlcularly to a composition of this character especially adapted for use as a superficial coating for paper, for the purpose of protecting same from the action of moisture or fluid.
By means of the application of the composition of our invention to low grade paper stock, on either or both sides thereof, or as a binder between superimposed plies of such stock, this stock is no t only made impermeable by moisture, or fluids, but has imparted thereto properties similar to those of parchment paper. Furthermore; paper stock treated with the composition of the invention is very much stronger than untreated paper stock of the same grade and weight. 1
The composition that its application to paper does not change the color of the paper, and in fact is imperceptible thereon except in so far as it imparts a parchnient-like finish thereto. The
composition as applied to the paper is odorless and has no injurious effects upon the paper, either -as to its tlssues, or its surface finish.
a saponified .vegetable oil, emulsified in water, this emulsion having incorporated therein aluminum acetate. In practice we have found that highly satisfactory results are obtained by using as the-oil ingredient, a
soap known commercially as Marseilles soap which analyzes substantially as follows :lVater approximately 22%, total fatty acids, including about 8% free fatty has little or no body, so

acids, 68%, alkali about 8%, impurities 2%. The oil used'in this soap is derived from the cocoanutor copra. This oil apparently reacts with the aluminum acetate producing insoluble salts, the excess of the oil being sufficient to impart flexibility to the paper, 'or other materialjtrc ated with the compound.
lVe believe that-the insolubility of the compound after application to the paper,
or other material, results from the chemical reaction between the said oil and the aluminum acetate andthe small percentage of alkali in the soap is of secondary importance. 1W
, lVhile in actual practice wehave used:
'saponified cocoanut oil, we believe that other vegetable oils such as cottonseed oil, could be advantageously used as a substitute therefor.
In the production of the compound, we employ the quantities of the several ingredients specified below and compound them as described.
In compounding substantially 16 gallons of the composition we first place approximately 15 pounds (avoirdupois) of Marseilles soap in emulsion in 14: gallons of water. preferably distilled water, bringing the-mixture to substantially 212 F., orthe boiling point thereof. lVhen the mixture has been brought'to the boiling point, we add approximately 2 gallons of distilled water and permit the temperature of the mixture to fall below the boiling point without, however, cooling it materially.
- time of the addition of the alumii'uun acetate, is too cool, or if the mixture cools too rapidly after such addition.
If desired, coloring matter may be added to the compound but this is not essential to the invention.
\Vhcnadding the aluminum acetate solution, this solution should be slowly mixed iio with the emulsion, but thereafter the compon claim as new and desire to have protected ,by- Letters Patent is sition should not be agitated.
We used distilled water to avoid-possi-i bility of impurities which might interfere with uniformity in quality of the composi- 7 tion, although, we do not consider it absok, p lutely essential to distil the water beforeplacing the saponified oil in emulsion therein.
- sired, various mechanisms for spreading the "composltlon upon the paper may be em- The composition thus produced is sufficiently viscous to be readily applied to sheets of paper with abrush, although, 1f deployed.; The composition is sufliciently fluid, however, by a dipping process 1f desired.
After application topaper, or other material, the composition should be allowed-to dr under normal temperatures.
hen dry, the composition forms a superficial, uniform coating upon the surface of the paper sufficiently bonded to the fiber to insure permanency of this surfacing. The pores of the paper are well filled with the composition, and the flexibility of the composition prevents the formation of crackstherein through which water might seep in a manner to penetrate the and thus destroy its waterproof qualities. With some grades of paper, the composition will have an effect on the paper which causes thesurface to be roughened similar to linen parchment papers. In all gradesof pa ers upon which we have used the compo-.,.
sition, we find that the strength of the paper is materially increased. a
.We have also secured good results by using the composition as a binder between peparate plies of paper, not only more or ess firmly uniting the plies, but providing an intermediate stratum havin waterproof.
property, in thefinished pro not in addition to the surface coating on' either or both sides thereof.
The proportions varied without departing from the s irit and scope of theinvention, no exactitu e as to these proportions being requisite.
While we have specified the use of Marseilles soap in the production of the comosition, other soaps might be-used in lieu thereof, although, we have not secured highly satisfactory results with the use of soaps made from animal fats.
It is not our intention to limit the invention to the precise characteristics of the composition or the steps of the process above specified, it being apparent that such may be varied withoutv departing from the spirit and scope of the invention.
