摘要： Provided are: an organic electronic material which can be easily multilayered and that can be used in substrates, such as resin, that cannot be processed at high temperatures; an ink composition containing the same; an organic thin film formed using said organic electronic material or said ink composition; and an organic electronic element and an organic EL element that are formed using said organic thin film and that have a superior luminous efficacy and emission lifespan than conventional elements. Specifically, provided are: an organic electronic material that is characterized by containing an oligomer or a polymer having a structure that branches into three or more directions and has at least one polymerizable substituent; an ink composition containing said organic electronic material; and an organic thin film prepared using the aforementioned organic electronic material. Further, provided are an organic electronic element and an organic electroluminescent element containing said organic thin film.
