Abstract
A coating for use with a hydrophilic sheet substrate to form a lithographic printing plate precursor, including at least one Compound A silane compound and at least one Compound B phosphinic acid or organic derivative thereof. Compounds A and B experience a synergistic interaction which substantially increases adhesion to the substrate of areas imaged by radiation. The resulting plate is exhibits high on-press durability suitable for high volume commercial uses without a preheat step prior to development, even when imaged with lower levels of radiation such as violet lasers. A method of preparing a lithographic printing plate includes imagewise exposing the coating on a surface of a hydrophilic substrate to violet radiation and developing in an alkaline aqueous solution without preheating.
