A film-forming ink includes a film-forming material and a liquid medium in which the film-forming material is dissolved or dispersed. The liquid medium contains a first component which has a viscosity of less than 20 cp and a second component which has a boiling point at an atmospheric pressure within a range of ±30° C. relative to the boiling point at an atmospheric pressure of the first component and has a viscosity of 20 cp or more, and the second component is contained in an amount of 20 parts by weight or more and 500 parts by weight or less with respect to 100 parts by weight of the first component.

From a viewpoint of achieving a high-performance organic light-emitting element, ensuring a certain degree of flatness in a coating film obtained by a wet film forming method may not be sufficient. As a result, a desired performance of an organic light-emitting element to be obtained, may not be obtained. Therefore, an object of the present invention is to provide an ink composition for an organic light-emitting element, which can prevent the generation of waviness. There is provided an ink composition for an organic light-emitting element, including: an organic light-emitting element material; a leveling agent; and a solvent, in which the leveling agent is a block copolymer formed by performing copolymerization of at least a siloxane monomer and a hydrophobic monomer.

A multi-fluid kit for three-dimensional printing can include a fusing agent and a detailing agent. The fusing agent can include water and a radiation absorber. The radiation absorber absorbs radiation energy and converts the radiation energy to heat. The detailing agent includes a lipophilic phase discontinuously dispersed within an aqueous phase by a surfactant. The lipophilic phase includes an organosilane having a central silicon atom coupled to a C6 to C24 aliphatic or alicyclic hydrocarbon and multiple hydrolyzable groups. The organosilane is present in the detailing agent at from about 1 wt % to about 20 wt %.
