Abstract:
1. An ink composition to be ejected by an ink jet forming image system, comprising: non-microencapsulated silver particles; and water, wherein when a composition formed of components of the ink composition other than the water is held in an atmosphere at an ambient temperature of 23° C. and a relative humidity (RH) of 50%, the equilibrium moisture content of the composition is in a range of 2 to 7.8 percent by mass, and wherein the mean particle diameter d90 in a grain size accumulation curve of the non-microencapsulated silver particles is in a range of 10 nm to 100 nm, and wherein the silver particles do not contain 0.1 percent by mass or more of particles having a particle diameter of 150 nm or more on a volume basis, wherein the initial glossiness at 60° is at least 525 and the glossiness at 60° after O-Zone exposure is at least 423.
