Ink composition and method for ink jet recording

摘要

An ink composition and method for ink jet recording are disclosed. The ink composition comprises a coloring agent and additives which are adjusted to bring the roundness of dots formed on a recording medium, such as paper, of from 50 to 80 g/m2, to be at least 0.75 where said roundness (D) is represented by the formula D=4 pi xS/L2 where S is the area of each dot, L is the circumferential length of the dot and pi is the circular constant. The ink composition has good ink drop projection stability, good storage stability and a superior property for producing highly densed dots having an improved configuration close to a perfect circle on the recording medium.
