Abstract:
A method for providing a positive image, the method consisting essentially of the steps of:A) imagewise exposing a laser-imageable, positive-working imaging layer of a photosensitive element with infrared radiation to produce an exposed layer comprising imaged areas;B) contacting the exposed layer with an aqueous alkaline developing solution to remove the imaged areas and form the positive image; andC) optionally, treating the element with a finisher; in which:the photosensitive element comprises a support having thereon the laser-imageable, positive-working imaging layer;the laser-imageable, positive-working imaging layer comprises:i) a phenolic resin comprising phenolic moieties,ii) an infrared radiation absorbing compound, andiii) a non-photosensitive compound capable of providing sites for hydrogen bonding with the phenolic moieties of the phenolic resin.
