摘要
There is provided a material for an anode buffer layer which permits the use of an organic solvent as a solvent of an anode buffer layer-forming solution, and is capable of forming an anode buffer layer that does not dissolve even when coated with a luminescent layer-forming material solution containing an organic solvent as a solvent, and which is capable of producing an organic EL element having high electrical power efficiency and long life. The composition for an anode buffer layer includes an electron-accepting compound and a high-molecular weight compound having a structural unit represented by the following formula (1) or the following formula (2) and having a weight average molecular weight of 20,000 to 1,000,000 as measured by GPC: wherein in each of the formulae (1) and (2), plural R a s are each a hydrogen atom or an alkyl group, with at least one R a being the alkyl group, plural R b s are each a hydrogen atom or an alkyl group, plural R c s are each a hydrogen atom, an alkyl group or the like, X is a single bond or the like, Y is a structure derived from a vinyl group and the like, and p is 0, 1 or 2.
