<p><P>PROBLEM TO BE SOLVED: To provide ink for a ballpoint pen, having uniform and high glitter on a drawn line, high stability with the lapse of time, and good runoff properties from the tip of a writing utensil by formulating a metal-deposited resin and metallic particles appropriately. <P>SOLUTION: The ink composition obtained by formulating the metal-deposited resin and the metallic particles is regulated so that the content of the metal-deposited resin based on the whole ink may be≥0.5 wt.% and≤15 wt.%, and the average particle diameter A of the metal-deposited resin and the average particle diameter B of the metallic particles may satisfy the following relations: 40μm≤A≤200μm; 5μm≤B≤150μm; and A>B. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
