It has been shown that the thermotensographic process 
in the layer of a copper dibromide solution in ethanol followed by 
catalytic reduction of copper in a hydrogen current at 450oC 
can be used to obtain conducting lines. It has been established 
that in an open liquid layer lines of isolated small crystals of copper 
are formed, and in a layer of a closed volume lines of intergrown 
small crystals are formed due to the evaporation-convective intensification 
of the image. In the first case, the lines do not conduct electric 
current, and in the second one their specific resistance is 4·103 times higher 
than in monolithic copper.
