Abstract
A positive-working lithographic printing plate is used to provide a positive image without a post-exposure baking step and without any floodwise exposure steps. The printing plate includes an imaging layer that is imageable using an infrared radiation laser. The imaging layer consists essentially of a phenolic resin and an infrared radiation absorbing compound.
