Abstract
Abstract An ink for ink-jet recording is provided which comprises a liquid composition essentially comprised of a coloring matter, a volatile solvent having a vapor pressure of 1 mmHg or more at 25° C., and a material being solid at room temperature and having a molecular weight of 300 or more; and prepared so as to satisfy formula B 1 /A 1 ≧3, assuming viscosity as A 1 cP at 25° C. measured when the content of the solid material in said composition is 10% by weight, and assuming viscosity as B 1 cP at 25° C. measured when the content of the solid material in said composition is 30% by weight. An ink-jet recording process employing the above-mentioned ink is also provided.
