Abstract
The invention relates to solutions of at least one organic semiconductor containing at least one high-molecular constituent, in a solvent mixture of at least three different organic solvents A, B and C. The invention is characterized in that the solvents A and B are good solvents for the organic semiconductor, the solvent C is a bad solvent for the organic semiconductor, and Sdp.(A)<Sdp.(C)<Sdp.(B) holds good for the boiling points (Sdp.) of the solvents. The invention also relates to the use of said solutions in printing methods for producing layers of the organic semiconductor on substrates, especially in the electronics industry.
