As small as x light-absorbing particles. any substances that can almost completely absorb infrared: iy4ii (for example, in , length from 0.76 to 5. micron): bend, thermal pigment mites, such as carbon black, or dyes, such as sulfuric dyes., -nanrymer sulfur black, small particles of meth t.yuv, such as silver chloride, silver broth, etc. These light-colored particles of small particles 5 are located in the inner part of the thermal-film film 3 or applied to its back surface. In addition, small light and blue particles 5 may partially applied to n. 3 from the side of the grid 2 through the holes in the lower one, i.e., excluding those areas in which ileika 3 is glued to the grid 2. In close contact with the thermoplastic film 3, which shrinks when heated, there is a film 6 with the original, made () Vlen11a photographically using silver salts, (In order to impart a pattern to n, 1 nook images of each other from one another), (by them (yyrv.che must be due to .KIKI 6 s original.yu.ma, corresponding to the site .LV, andrepresents em ss / battle pro.zrachichyu basis 7 ptechnikp, and n a (; boi.x K |) and x uchaska.

In this m c, it is important Iu that n.iCHKa 6 with original (;. m should py; iac). in such a way that the light termination area of the 8th section (; Dils on its entire surface on the surface so that the heat generated in this area cannot be directly transferred to the thermal shrinkage film 3, it is also desirable that the backing film 6 with the original, i.e., the light-dividing portion, consisted of a transparent heat-insulating film.

The gels of the pattern produced by the TCILIO create approximately the same temperature distribution as shown in FIG. 5. At the same time, the temperature is especially high in the area of the openings of the grid 2 (Tz is the temperature of a part that was not irradiated with light: T over terachtra section AB.

The reducing parts of the fox 3 are assembled on the grid 2 in the form of a stop 10, in particular around its intersection zones, as shown in FIG.
