Abstract:
PROBLEM TO BE SOLVED: To provide an IR-sensitive composition capable of manufacturing a negative printing plate precursor having long storage stability, capable of continuously making a large number of copies and having a high resistance to development chemicals. SOLUTION: The IR-sensitive composition contains a free radical polymerizable system comprising a polymer binder, at least a component selected from the group consisting of an unsaturated free-radical polymerizable monomer, a free-radical polymerizable oligomer and a polymer containing a C=C bond in backbone and/or branched chain group, and an initiator system.
