摘要： There is provided an ink composition for an organic light-emitting device which can easily form a light-emitting layer having more excellent uniformity and which is suitable for forming a light-emitting layer by a wet method. The ink composition includes a light-emitting material, a binder resin, and a solvent, the binder resin containing a multi-branched copolymer of a monovinyl compound composed of a styrene-based monomer as an essential component with a multifunctional vinyl compound containing two or more ethylenically unsaturated double bonds, and the copolymer having a weight-average absolute molecular weight within a range of 200,000 to 800,000 determined by gel permeation chromatography using a multi-angle laser light scattering detector and a degree of branching within a range of 0.20 to 0.55 determined from an inertial radius. An organic light-emitting device includes a positive electrode; a light-emitting layer, and a negative electrode, the light-emitting layer containing the binder resin.

摘要： An object of the present invention is to provide a polymer obtained from novel monomers, a composition containing the polymer, an electronic material composition, and an electronic element, the polymer, by being added to the electronic material composition or ink applied for coating film formation, improving the smoothness (leveling property) of a coating film to be obtained without deteriorating a driving stability of the electronic element. With the novel siloxane monomers, the polymer thereof, the composition containing the polymer, and the electronic material composition according to the present invention, it is possible to produce a smooth organic thin film. The electronic element including either of these compositions has a prolonged element lifetime and improved driving stability.

摘要： An object of the present invention is to provide a novel hetero ring-containing siloxane polymer, a composition and an electronic material composition containing the polymer, and an electronic element, which do not cause a decrease in luminous efficiency and driving stability of an electronic element, by adding the polymer to an electronic material composition or ink to be used for coating film formation. It has been found that the electronic element produced from the novel hetero ring-containing siloxane polymer, the composition and the electronic material composition containing the polymer exhibit improved luminous efficiency and driving stability, thereby completing the present invention.
