A different pigmentation requires changes to the aforementioned composition, which must be taken into account the working behavior or the effect of the color and that in the transferable material ultimately desired properties are to be made. The "cohesion" refers to the property of the color film, if it is on the carrier film in its usual state of use as a transferable Material is available. The compositions of this range are very suitable if the one used The backing is in the form of a tape or a sheet, since then there is no difficulty due to peeling occur when the tape or web is rolled.

A composition as described above with high cohesion useful for printing a variety of characters or letters were used on silicone-coated vegetable parchment, was subjected to a test to determine the pressure at various temperatures, the is required to make 95% of the characters or letters to be transferred to a recording surface made of paper. At the same time, the "behavior of use" by subjective measurement of the ease of use of the material if one individual character was transferred by means of the pressure of a pencil. The results are in the shown in the table below.

The invention is explained in more detail below with the aid of examples.

Example 1

A carrier sheet or a carrier sheet made of a silicone-coated paper is provided with colored transferable material or characters printed with the following composition Has:

preferably 44.5 70% polyvinyl ethyl ether dispersible

sion in toluene 5 to 2O ₅

preferably 19

Pigment (carbon black) 4 to 8,

preferably 5.0

In the above composition, instead of butanol, any other alcohol, ethi or esters can be used, which is a solvent for the polyvinyl butyral, for example ethylene glycol monoethyl ether or acetate; Instead of white spirit, any other aliphatic or aromatic solvent for the wax and any other solvent in place of the toluene for the polyvinyl ether such as gasoline can be used.

Example 2

26% polyvinyl butyral solution in butanol 29.0 70% polyvinyl ether dispersion in toluene 9.0

Titanium dioxide 17.5

50% terpene resin 115 solution in white spirit 9.5

At the higher temperatures, a higher pressure is required due to a loss in stickiness or adhesive strength on those surfaces where the wax is half-melted, and as a result increasing adhesion of the color to the backing paper. The execution works most satisfactorily between 10 and 30 ° C, which means that in practice almost every climate or climatic change is included.
