Abstract: A selectively alterable intermittent tattoo ink is a type of tattoo ink that is invisible or visible until an activating chemical is applied to it, creating a chemical change in the ink pigment which results in the ink being visible, invisible, partially visible or changing color. A tattoo is formed by the injection of the selectively alterable intermittent tattoo ink such as a chemically reactive pH sensitive pigment, along with an inert carrier and a temporary activating agent, (so the ink will be temporarily visible), into the skin with a traditional tattoo gun. The invisible tattoo ink can then be activated by the application of a chemical activating agent either to the skin over the tattoo site or by a normal or abnormal physiological chemical change within the body. The activating agent is removed by washing, the application of a neutralizing agent or by the natural metabolic functions of the body resulting in the tattoo being invisible or in its deactivated state once again.
