Abstract: The invention concerns fusible mixtures of high electroconductivity which consist of(a) 0.5 to 99% by weight, relative to the total weight of the mixture, of a TCNQ complex of the formula ##STR1## in which R and R.sub.1 independently of each other stand for an optionally substituted aliphatic, cycloaliphatic or araliphatic radical having 1 to 30 C atoms andn is 1, 2 or 3 or a fraction between these numbers and(b) 99.5 to 1% by weight, relative to the total weight of the mixture, of one or more special liquid organic compounds.

Abstract: TCNQ complexes with organic pyridinium ions, which may be kept in a molten condition for a relatively long time without the electrical conductivity thereof being substantially reduced after cooling.

Abstract: Fusible mixtures of high electrical conductivity which consist of from 0.5 to 99%, by weight of a TCNQ complex.

Abstract: Metallized laminated materials are obtained by coating a solder-resistant core material with a non-conductive polymer film, and subsequent activation and wet-chemical metallization of the polymer film, the activation being carried out, without oxidative pretreatment, on the polymer film before it has hardened completely, and the final hardening only being effected after the metallization. The materials thus metallized are suitable for the production of printed circuits.

Abstract: This invention relates to a process for the preparation of charge transfer complexes containing 7,7,8,8-tetracyanoquinodimethane by the reaction of TCNQ with organic cation iodides or by the reaction of nitrogen-containing heteroaromatic compounds and tertiary amines with H.sub.2 TCNQ, using smaller quantities of solvent than that required for complete solution of the TCNQ.
