Abstract
Improved inkjet ink compositions have 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 inkjet ink compositions of the invention include a carrier, a colorant that is soluble or dispersable in said carrier, and a sufficient quantity of at least one acetylenic alcohol to reduce the corrosiveness of said ink composition to metal placed in contact with said ink composition. The inkjet ink compositions may also include at least one acetylenic alcohol that contains a terminal acetylene and an &agr;-hydroxy group. A method for reducing corrosiveness of an inkjet ink composition includes adding to said inkjet ink composition a sufficient quantity of at least one acetylenic alcohol to reduce the corrosiveness of said ink composition to metal placed in contact with said ink composition.
