A lithographic printing plate precursor is disclosed including a support and a coating comprising (i) a photopolymerisable layer including a polymerisable compound and an optionally substituted trihaloalkyl sulfone photoinitiator, and (ii) a toplayer provided above the photopolymerisable layer; characterized in that the toplayer includes an infrared absorbing dye capable of forming a print-out image upon exposure to heat and/or IR radiation.

Lithographic printing plate precursor

A negative-working lithographic printing plate precursor includes a coating including vinylogous vitrimer particles. The vinylogous vitrimer particles include a resin having at least one moiety of formula (I), (II), and/or (III): 

A negative-working lithographic printing plate precursor includes a support and a coating containing a photopolymerizable layer including a polymerizable compound including: 

A negative-working lithographic printing plate precursor includes a support and a coating containing a photopolymerisable layer; characterized in that the coating includes a compound including at least one moiety having a structure according to Formula (I) at a level above 10% wt and below 40% wt relative to the total dry weight of the ingredients of the coating: 

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.
