WRITING PASTE Lassie Jozsef Biro, Buenos Aircs, Argentina, assignor, by mesne assignments, to Eterpen Sociedad Anonima Financiera, also known as Eterpen S. A., Buenos Aires, Argentina, a company of Argentina NoDrawing. Original application December 27, 1938, Serial No. 247,969, now Patent No. 2,265,055, dated December 2, 1941. Divided and this application April 23, 1941, Serial No.

3 Claims. (Cl. 10625) 'Ihis invention relates to writing materials, such as inks; dyes or the like, and more particularly to highly viscous or pasty compositions containing inks or dyes and adapted for use in fountain pens of the type having at its writing end a spherical ball rotatably mounted within an inclosure at the free end of a support having an internal longitudinal opening in communication with a reservoir for the paste located within the hollow barrel of the fountain pen or the like.

This application is a division of my application Serial No. 247,969, filed December 27, 1938, which application matured into Patent No. 2,265,055 on December 2, 1941.

The writing pastes known prior to my invention are generally unsatisfactory and cause trouble with the pen as the properties required of such pasty writing materials are such that when enclosed in the pen they should remain viscous enough to ooze or be forced toward the writing ball, and yet while being deposited on the writing surface in the act of writing should dry with considerable rapidity. Writing pastes known prior to my invention have been such as to lead to the cloeging of the ball in its inclosure owing to the drying of the paste on the exposed surface of the ball and in the gap between the ball and the wall of its inclosure. Such writing pastes as known prior to my invention have lacked the property of remaining at a suiliciently low viscosity for considerable periods of time on exposure to air as to ensure that the ball can at all times turn freely so as to convey the writing paste properly to the writing surface, and not only write satisfactorily and eiilclently but at the same time prevent the ball from clogging up, thus rendering the writing operation either impossible or unsatisfactory. My new writing paste fulfills two apparently contradictory conditions as regards its humidity content in that it enables satisfactory and continuous operation of the pen when de-' these two materials are such that they can readily be separated by physical means as, for example, by absorption into the writing surface, but will when exposed to air on a non-absorptive surface remain intheir original pasty condition so 2 that the writing ball will at all times be surrounded by a sufllciently fluid paste to enable proper delivery of the paste during writing, and will also enable the rapid drying of that portion of the writing material on the paper which has not been absorbed by the paper.

By selecting as the drying component a material which is not absorbed by the writing paper or the like, and for the non-drying component a substance readily absorbed by such writing surfaces. the components will when the paste is deposited on said surfaces in the act of writing become rapidly separated, the non-absorbing rapidly drying component remaining exposed to the air on the writing surface for quick drying, and the non-drying component absorbed into the material of the writing paper or the like. The sticky or tacky drying material may consist, for example, of a glue or any polysaccharide, and the non-drying substance may be composed of a cholesterised oil or, for example, glycerin. In general, it has been found convenient to use for the non-drying material a fatty or fat-like substance which shall at least have the properties of the fatty or greasy bodies, as I have found that such materials not only act as lubricants for the ball but satisfactorily fulfill all of the other requirements of a writing paste according to the present invention.

Purely by way of example and without myself to the specific ingredients named, the writim paste may be prepared by mixing a powdered aniline dye with glycerin in approximately equal proportions, and adding to this mixture from 35% to 40% of tacky dextrine obtained by mixing powdered dextrine with water and heating the resulting mixture. Other ingredients may be added to the paste so obtained as desired. For

example, I may add a small-amount of acetic acid to brighten the color and serve as a preservative for the paste; or, if desired, carbolic acid may ance with my invention I have provided an im-' proved writing paste suitable for use in a ball pointed fountain pen of the type referred to, while remaining sufficiently l quid on exposure to air at the surface of the ball and yet drying 'enable the use of the fountain pen for rapidly when applied to an absorbent writing surface.

jWhile I have described above a satisfactory writing paste, I wish it understood that the same is susceptible of modification and change withcomprising approximately equal proportions of aniline dye and glycerine, and from 35 to 40% of tacky dextrine obtained by mixing powdered dextrine with water and heating the mixture, whereby the glycerine will act as a lubricant for the ball and maintain the writing paste moist at the surface 01' the ball to eflect good writing and lon periods of time i'roma single filling.

i 2. A writing paste for ball pointed fountain pens, consisting of a mixture comprising approximately equal proportions of powdered aniline dye and glycerine, from 35 to 40% of tacky dextrine obtained by mixing powdered dextrine with water and heating, and a small amount 01' acetic acid.

in certain limits without departing from the 3. A writing paste adapted to be used in ball pointed fountain pens, comprising a mixture of powdered aniline dye with glycerin in approximately equal proportions, tacky dextrine in an amount ranging from 35 to 40 per cent which has been obtained from heated powdered dextrine and water, and acetic acid to brighten the color and serve as a preservative for the paste, whereby to provide a writing paste in which when writing the glycerin will be separated from the mass by quick absorption into the fibrous material of the writing paper, and the dextrine becomes "set upon the surface of the paper, the glycerin acting as a lubricant for the ball.
