Abstract

Radiation-sensitive compositions, printing plates containing such compositions, imageable by infrared and ultraviolet/visible radiation and imaging method using same. The compositions comprise a thermal-activated acid generator; a crosslinking resin; a binder resin comprising a polymer containing reactive pendant groups selected from hydroxy, carboxylic acid, sulfonamide, and alkoxymethylamides; an infrared absorber; and optionally a UV/visible radiation-activated acid generator for UV/visible sensitization.
