Zusammenfassung:	FIELD: producing copper tracks on insulating substrates. ^ SUBSTANCE: negative image of track is projected onto copper halide solution layer in organic solvent of substrate with the result that concentric capillary flow occurs in layer which transfers solution to illuminated sections of substrate wherein copper halide tracks remain upon solvent evaporation. These tracks are reduced to copper ones in hydrogen current at temperature sufficient to conduct reducing reaction. ^ EFFECT: facilitated procedure, reduced cost and copper consumption, improved environmental friendliness due to elimination of wastes. ^ 1 cl, 3 dwg
