Abstract

Photoconductive compositions useful in the fabrication of digital, laser-imaged offset printing plates. The compositions comprise a mixture of (a) an infrared-sensitive organic photoconductor sensitive to light in the wavelength range of 700-9090 nm; (b) a visible light-sensitive organic photoconductor sensitive to light in the wavelength range of 400-700 nm; (c) an ultraviolet-sensitive organic photoconductor sensitive to light in the wavelength range of 300-400 nm; and (d) a binder.
