Zusammenfassung:	PURPOSE: A pigment composition is provided to stably show the vivid color of an ink composition and to prevent the separation of organic pigment and inorganic pigment without separate anti-sagging agent. CONSTITUTION: A pigment composition used for ink for a marker pen comprises colored pigment and emulsifier for preventing the color paint from being dispersed. The colored pigment is a mixture of an organic pigment with a particle size of 120-150 micron and an inorganic pigment with a particle size of 120-150 micron. A method for preparing the pigment composition comprises the steps of: (i) pulverizing organic pigment and inorganic pigment to a particle size of 120-150 micron; and (ii) injecting an emulsifier in the organic pigment and inorganic pigment powder and stirring the materials for 1-2 hours.
