ABSTRACT:
A method of forming an image on a substrate is described which comprises blending a desired coloring pigment, adding the coloring pigment to a water soluble photoresist, coating the substrate with the pigmented photoresist, exposing the photoresist to actinic radiation to harden the parts of the photoresist occupying the desired image area, and removing with a water based solvent the unexposed photoresist.
