Hello everyone,
I was just wondering if there is any type of transparent ink that could be permanently activated by heat or intense light (laser).
Preferably I am planning to use a laser light to activate the ink.
I am trying to coat a piece of metal (or paper or etc.) with this ink (which is invisible). Then I want to write on the coating using a laser light. I am supposed to shine a laser beam to the coating in order to draw fine lines/drawings. The laser beam is supposed to activate the ink (reveal its color) as it pass through. The laser is supposed to activate the color of the ink and lock it (meaning, the color is supposed to stay on coating after laser has passes through).
I was just wondering if this is possible and if there is an ink with this kind of characteristic or if I can modify an ordinary ink to behave like this.
Thanks
