A composition for inkjet is adapted to be discharged by an inkjet method. The composition includes a metal powder having a surface, metal or metal alloy constituting at least the surface of the metal powder, an organic solvent, and a binder resin. The surface of the metal powder is modified by chemical bonding with a fluorinated silane composition and/or a fluorinated phosphate compound as a surface preparation agent.

Composition for inkjet and recording material

A material includes a layer produced by an ultraviolet-curable composition for inkjet that includes a polymerized compound and a glittering powder. The glittering powder has a scale-like shape. An average thickness of the glittering powder is more than 10 nm and less than 100 nm, an average grain diameter is less than 3.0 &#x3bc;m, and in addition, a maximum grain diameter is less than 5 &#x3bc;m.

Material including layer produced by ultraviolet-curable composition

The invention provides metal powder constituted from metal particles. Each of the metal particles comprises a base particle having a surface and a metal material constituting at least the surface of the base particle. The base particle is subjected to a surface treatment with a fluorine type phosphoric acid ester.
