Disclosed are: a polymer for treating the surface of a medical device such as a contact lens to suppress the reduction in lubricity of the device even when the device is scrubbed; a medical device having the polymer on the surface so that the reduction in lubricity over time is suppressed; and a wetting agent containing the polymer. The polymer for treating the surface is a copolymer which is water-soluble and includes as constitutional units the following monomers A and B: monomer A: a monomer containing a (meth)acryloyl group and an ester or amide structure in a molecule, in which the ester or amide structure is not constituted by including a part of the (meth)acryloyl group; monomer B: a monomer containing a (meth)acrylamide group in a molecule and having a structure different from that of the monomer A.

Copolymer, wetting agent, medical device, and method for producing same

Provided are an aromatic amine compound as represented by formula (1), used for improving light extraction efficiency and color purity of an organic light-emitting element, an organic light-emitting element material containing the aromatic amine compound, an organic light-emitting element covering layer material containing the aromatic amine compound, and an organic light-emitting element containing the aromatic amine compound. The organic light-emitting element achieves high light-emitting efficiency and color reproducibility. The organic light-emitting element can be used as organic EL display, backlight source for liquid crystal display, illumination, light source for measurement devices, indication board or identification lamp etc. The organic light-emitting element significantly improves light extraction efficiency and has superior color purity.
