The present invention relates to a composition for use in an organic device, comprising at least two cross-linking compounds, wherein
each of the at least two cross-linking compounds is a polymer that has a hole-transporting site and constitutional repeating units, the at least two polymers having different average numbers of cross-linking groups per constitutional repeating unit and/or different numbers of cross-linking groups in portions other than the constitutional repeating units, and
wherein the cross-linking compounds are compounds having a partial structure of the following formula [109]:
The present invention further pertains to an organic electroluminescent element that comprises an anode and a cathode on a substrate and at least one organic layer disposed between the anode and the cathode, wherein at least one organic layer is a layer that is produced by forming a film of the composition for use in an organic device above.
