Abstract
A photopolymerizable composition that is cured with visible light or an infrared laser and is used as a recording layer in a negative planographic printing plate precursor. The photopolymerizable composition is cured by exposure and includes (A) a polymerizable compound that is solid at 25° C. and has at least one radical-polymerizable ethylenically unsaturated double bond in a molecule, (B) a radical polymerization initiator, (C) a binder polymer and, as required, (D) a compound generating heat by infrared exposure.
