<P>PROBLEM TO BE SOLVED: To obtain an improved ink-jet ink composition having reduced corrosiveness of the ink without adversely affecting printing characteristics of the ink composition. <P>SOLUTION: The improved ink composition has a sufficient amount of an acetylenic alcohol incorporated therein to reduce the corrosiveness of the ink without adversely affecting the printing characteristics of the ink composition. The ink-jet ink composition comprises a carrier, a colorant that is soluble or dispersible in the carrier and a sufficient quantity of at least one acetylenic alcohol to reduce the corrosiveness of the ink composition to metal placed in contact with the ink composition. The ink-jet ink composition may also include at least one acetylenic alcohol that contains a terminal acetylene and an α-hydroxy group. A method for reducing corrosiveness of the ink-jet ink composition includes adding to the ink-jet ink composition a sufficient quantity of at least one acetylenic alcohol to reduce the corrosiveness of the ink composition to metal placed in contact with the ink composition. <P>COPYRIGHT: (C)2003,JPO |
