Abstract

Disclosed is a method of making a lithographic printing plate which includes providing a lithographic printing plate precursor having a coating therein, image-wise exposing the coating, and developing the precursor. The coating includes (i) a contiguous photopolymerizable layer of a photopolymerizable composition or (ii) a contiguous intermediate layer with a photopolymerizable layer of a photopolymerizable composition thereon. The photopolymerizable composition includes a polymerizable compound, a polymerization initiator and a first polymer. The contiguous photopolymerizable layer or the contiguous intermediate layer also includes an adhesion promoting compound and a second polymer.
