Patent ID: 6863391

Claim:
A liquid composition to be applied to a recording medium with ink containing a coloring material to form a colored section on the recording medium, said liquid composition containing at least a solvent and fine particles reactive to said coloring material, the specific surface area of aggregates of fine particles formed from the liquid composition by way of steps (1) through (4) listed below being 70 to 250 m 2 /g as determined by the BET nitrogen adsorption/desorption method, (1) a step of drying the liquid composition at 120° C. for 10 hours in the atmosphere to evaporate the solvent; (2) a step of raising the temperature of said dried product resulting from the step (1) from 120° C. to 700° C. in an hour and baking it at 700° C for 3 hours; (3) a step of gradually cooling the baked product resulting from the step (2) to room temperature and pulverizing it; and (4) a step of deaerating the powder obtained in the step (3) by vacuum at 120° C. for 8 hours to obtain aggregates of fine particles.
