Abstract
A photosensitive polymer-containing system containing: (a) an energy sensitive polymer having a linear hydrocarbyl backbone and pendant peptide groups with free-radically polymerizable functionality attached thereto; (b) a vinyl-halomethyl-s-triazine capable of free-radical generation upon excitation with electromagnetic radiation having a wavelength of from about 330 to 500 nm; (c) an organic acid having a pKa of from about 1.8 to 5.5; (d) a leuco dye; and (e) a binder. A colorant may optionally be added. The photosensitive systems exhibit an increased shelf-life and excellent photosensitivity.
