The Spiritesrbon-Yervalution process represents a quick, cheap and very successful process for making the above copies, but it has the great disadvantage that the dyes, which were sent out for the manufacture of the carbon paper, are strong in use rub off. This means that the person making a mitter copy can get stains on hands and clothes that are difficult to remove. One can beikoanaeiu this rear part to a certain extent by covering the dye-containing layer with a thin covering of a clear or pigmented one. Wax or other material that is a solvent for the dye. covered. Such a layer allows a spirit carbon paper to be kept clean, provided that care is taken, but an overbolag is not a completely satisfactory solution, since it must be transferable with the colored layer After the carbon paper has been removed, such overlays are otherwise ineffective. The master copy and the carbon paper adhere to one another somewhat, and if they are separated from one another, then detached particles of the transferable layer can fall out. in particular from the edges of the transferred surfaces * These particles are spread out in the tree in which the process is carried out, causing stains of color to appear on human skin and on items of clothing, but also on furniture, carpets, etc.

The yeast candy problems with spirit carbon duplicating papers have been the major drawback for many years. The present invention is now concerned with solving this problem _. in that the soiling material, ie the dye, is replaced by a colorless or almost colorless dye derivative, which is found on the copy paper

after the copying process has been completed, the desired color is produced. This solution to the problem of soiling is already known, and there are also various colorless or almost colorless dye derivatives * which can be used for the stated purpose. However, previous attempts to produce satisfactory clean carbon hectographic paper based on the general idea of using a colorless or nearly colorless dye derivative have been unsatisfactory for various reasons. It is an object of the present invention to provide a colorless or nearly colorless carbon hectographic paper which is satisfactory and which allows a general solution to the difficulties of conventional hectographic systems in an economical and practical manner.

According to the invention, the Spiritoarbon duplicating paper is produced with a colorless dye precursor, at the close of normal use in a sufficient ^ can be extracted from the transferable material to a colored t copy on the copy paper manufacture. As already mentioned, dye precursors of this type, ie colored materials which can develop colored copies on suitable copy papers, have been known for a number of years, but the use of these known materials in spirit carbon reproduction has not been satisfactory, either because of the very limited Solubility in suitable solvents or because of other disadvantages5 such as * instability under the necessary processing conditions or in their developed dye form. It was now possible to provide suitable colored dye precursors which are sufficiently soluble in the duplication liquids and which can be incorporated into transferable coatings for the alcohol carbon duplication, with a sufficient one

It has been found that a product which has such a wax coating has a better one Transfer of the transferable layer results, with the letter lines appearing wider, with them but still remain extremely clean and sharp. Hit another In other words, none of the advantages and also not the excellent behavior of the according to the invention due to the wax overlay Carbon papers are lost, while at the same time the behavior is improved, as namely hatter copies and hectographic copies thereof having a better appearance and greater satiety are obtained again.
