Title:
印刷組成物のための溶媒
Document Type and Number:
Japanese Patent JP2011517369
Kind Code:
A
Abstract:
A composition suitable for fabricating an electronic device such as an OLED using an ink-jet printing technique comprises a conducting or semi-conducting organic material and a solvent, the solvent having a boiling point of greater than 250° C. and a viscosity of less than 5 cPs. The composition preferably has a viscosity in the range between 0.1 and 20 cPs, and the solvent preferably has the formula: where R represents a C6 to C11 alkyl. The high boiling point of the solvent allows the ink to remain wet for a longer time after printing. This provides better process control during drying, resulting in more uniform films and greater control over the film profile. The low viscosity of the solvent enables jetting of the composition at high frequencies.
