摘要：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:;whereinn represents an integer equal to 0 or 1;L1 represents a divalent linking group;with the proviso that the carbonyl groups in Formula (I) are bonded to a carbon atom.

主权项：1. A lithographic printing plate precursor comprising: a support including a hydrophilic surface or a hydrophilic layer; and a coating including a photopolymerizable layer; wherein the coating includes a compound represented by Formula (IV): wherein R3 and R4 independently represent a terminal group; L4 and L5 independently represent a divalent linking group; and the compound according to Formula IV is present in an amount above 10% wt and below 40% wt relative to a total dry weight of ingredients of the coating.
