The resulting material for thermal transfer printing is cut into sheets of the required format (according to the subjects of the drawings) and used for coloring, for example, fabrics or semi-finished products from synthetic fibers (polyester, polyamide, triacetate or their mixtures) according to GOST 20272-78 and GOST 21724-76 . The conditions of thermal transfer are the temperature of the press 200-210 С, the contact time is 35-40 sec, the pressure in the contact zone is 1.5x10 Pa.

Example2. On a PET-6 sheet-fed gravure printing press (USSR), a 10% solution of oil in Kalos brand gasoline is applied at a speed of 120 g / m (Finl ndi) intaglio printing at a speed of 2 m / s.

The resulting material for heat-transfer printing is used for heat-transfer coloring, for example, furniture panels coated with polyethylene enamel PE-276. The conditions of thermotranslation: temperature 190-200 С, contact time 15-20 s, pressure in the contact zone 1.8x10 Pa.

Example 3. Ultraflex-106 A (GDR) flexographic printing machine on a parchment paper is applied a 7% NC solution in gasoline at a speed of 2 m / s, then the pattern is printed with sublimation printed CRS- Kami, for example, of the following composition, wt.%:

Then, on the same machine at a speed of 2 m / s, an 8% solution of NK in gasoline is applied. The obtained material for thermal transfer printing is used for coloring, for example, leather-like rubbers of the Kozhvilon type. Thermal transfer conditions: temperature 210-240 ° C, contact time 15-20 seconds, pressure in the contact zone 2.10 Pa. Example4. At the screen printing screen printing machine, a 15% NC solution in white spirit is applied to label paper using a No. 100 form (sieve). Then the image is printed with sublimation printing inks, for example, of the following composition, wt.%:

Then, on the coating machine, an I5% solution of NC in white spirit is added to a weight gain of 2 g / m. The material for thermal transfer printing is used for coloring, for example, household bags or polyester yarns (GOST 20272-78). The conditions of thermotranslation: press temperature 220 C, contact time 30-35 with pressure in the contact zone 1.5x10 Pa Example 5. On an offset printing machine: Romayor (GDR) on a 15 ty offset printing paper is applied a 5% solution of NK in white spirit. Then the image is printed with sublimation printing inks, for example, of the following composition, wt.%: Rosin-malein resin M- 8O25

Then covered with a 7% solution of NK in white spirit to a weight gain of 1.2 g / m. The material for thermal transfer printing is used for coloring, for example, articles made of non-woven glued sheets (OST 6-06-02-83). The conditions of thermotranslation: temperature 240 С, contact time 15 sec, pressure in the contact zone 1.2x10 Pa.

EXAMPLE 6 (Prototype Reproduction. On a 75 g / m intaglio paper on a deep printing machine at a speed of 0.33 m / s, a 15% aqueous solution of polyvinyl alcohol is coated.

A 15% aqueous solution of polyvinyl alcohol is then applied. The resulting Hbtfi material is used for dyeing, for example, fabrics made from synthetic fibers. For coloring leather-like leathers of the type of leather and polyester-coated products, this material cannot be used because of its adhesion to 10 of them.

In order to obtain comparable results by means of trans- porting pictures of the examples, polyester fabrics are colored (GOST 20272-15 78) and the sublimation transfer factor of dyes is determined by the formula

where K is the amount of dye transferred to the fabric during thermal transfer from the temporary bumping substrate, g / cm;

5 K and the initial amount of dye in the paint layer on paper, g / cm.

From paper and fabric, the dye is washed out with dimethylformamide (3-fold) d at 140 ° C, the optical density of the solutions obtained is determined, and the quantitative content of the dye in the solution and on the material is determined using a calibration curve.

The test results are tabulated.

As follows from the test results, the material for thermal transfer printing is characterized in comparison with the prototype by a significantly longer shelf life during which it provides high-quality coloring of a wide range of polymeric materials, including those that are not prototyped in the prototype.
