Description

during their preparation or during the grinding of the

Add dye or add them to the wax component 30 before grinding with the dye.

The invention relates to dye compositions which are alkoxylated when added to the dye component during their Fatty acid alkanolamides contain, for hectography production it has been found to be particularly beneficial, showed, the alkoxylated alkanolamide in the water

In the production of hectograph masses, melts of the dye that contain the dye are to be stirred in and then the dyes are to be dried in a mixture with the aid of grinders,
dispersed in a wax mass. The hectographs - as colorants that make up the main part of the hectographs

In the molten state, masses are transferred to storage graphene mass, usually 30 to 60 weight containers, and for further processing in percent, based on the total weight of the hectares Coating system in, for example, printing graphene mass, make up and within the framework of the or doctor blade methods can be used on the paper 40 of the present invention to be coated, applied. All conventional hectograph dyes can be produced with such hectography papers nen then after the transfer printing process to simple consideration, in particular triarylmethane dyes, Wise copies are made. such as crystal violet (Color Index No. 42 555), methyl

In the storage and processing of hecto violet (Color Index No. 43 535) or Victoria blue B graphene masses in the liquid state, 45 (Color Index No. 44 045) often occur, with mixtures also exhibiting considerable increases in viscosity. of dyes can be used.

When stored for a long time, the mass thickens synthetic waxes and oils, such as irreversible and is therefore used for further 50 carnauba wax, lanolin, petroleum jelly, paraffin, ozone useless for coating. kerit.

The color compositions according to the invention also differ in the case of prolonged storage and in the case of their from the higher temperatures customary in the Soviet patent specification for further processing 215 864 described printing inks for the textile are stable and flowable and are therefore for the coating printing in that the latter to improve the 60 processing of hectography papers to excellent Color yield an addition of non-alkoxylated manner suitable. Other nonionic emulsifying fatty acid alkylolamides included, whereby these antidotes are already used to make the grain over the alkoxylated fatty acid alkylolamides only hardness of di- and triarylmethane dyes to be distributed non-ionic, on the other hand cation-reducing and thus for hectographic purposes have an active character. The addition is made there to make 65 more suitable. Such emulsifiers show those usual in textile printing, but none or none for hectographic purposes for hectograph dimensions but unsuitable dyes, this dyeing remarkable viscosity stabilizing effect, substances also in the dye mass in considerably low- It was therefore surprising that the group of
