ABSTRACT:
The present invention relates to solutions and/or dispersions of organic semiconductors in a solvent mixture of at least two different organic solvents, characterized in thatA. Each of the solvents on its own has a boiling point of below 200° C. and a melting point of 15° C. or less,B. at least one of the solvents has a boiling point in the range from greater than 140 to less than 200° C.,C. the solvents used have no benzylic CH2or CH groups,D. the solvents used are not benzene derivatives containing tert-butyl substituents or more than two methyl substituents,and their use in printing processes for producing layers of organic semiconductors, especially for the electronics industry.
