Definitions
- the object of my invention is the production of a liquid copying composition to be applied in the form of a thin and smudge-proof coat to the.
- tion or emulsion according to my present invenaside from the film-producing component and v the dye contains only water
- the ordinary ap- Paratus used for dyeing the paper also may be employed for the purpose of applying this dyecarrying paste.
- Transcrit which also operates without the use of carbon paper.
- This process mostly used only for the local printing on of the copyin dye-coat, is employing. however, the very same and relatively expensive dyefilm of the carbon paper, 1. e. a dye containing one therefore also has to "apply a thin coat of a film-producing substance to the surface of the sheet to be copied on.
- Paper treated in accordance with the present invention such as, e. g., coated with a solution of latex, may be written and printed on like any ordinary P per treated with glue.
- the process therefore, also may be made use of ili' making forms to be copied either by hand or by means of the typewriter.
- the process is, e. g., applied as follows: The one side of a roll orsheet of paper first is impregnated with a solution containing, per litre, 20 grams of Revertex T (a latex-concentrate containing about 75% dry substance) to which, if need be and so desired, protective agents against a e. g. phenyl-betanaphtylamin,- are added.
- Revertex T a latex-concentrate containing about 75% dry substance
- a further pronounced difierence between the' present and the known processes is that the paper of the former has to be coated on both sides.
- the dye on the back of the sheet, bound by the sulfonates etc. known to the trade under the film-producing substance such as, e. g., latex,
- a protective meansragainst aging may be added.
- a variation of the process described consists in .using unglued paper, substituting the passing of the paper through a Revertex-solution for the After such a passage the coat is dried and then the dye-film spread on.
