A phototool having a fluorinated phosph(on)ate coating and methods of using the phototool.

Phototool coating

A process for making flexible circuits wherein the etching of a polymeric film is accomplished by dissolving portions thereof with concentrated aqueous base using a UV-curable 100% active liquid photoresist as a mask, comprising the steps of laminating the resist on a polymeric film, exposing a pattern into the resist, developing the resist with a dilute aqueous solution until desired image is obtained, etching portions of the polymeric film not covered by the crosslinked resist with a concentrated base at a temperature of from about 50&deg; C. to about 120&deg; C., and then stripping the resist off the polymeric film.
