1. A photosensitive resin structure for a printing plate, comprising:
a support (A);
a photosensitive resin composition layer (B) comprising a thermoplastic elastomer (B-1) comprising a monovinyl-substituted aromatic hydrocarbon and a conjugated diene, an ethylenically unsaturated compound (B-2), and a photopolymerization initiator (B-3); and
a non-infrared ray-shielding layer (C) ablatable with an infrared ray, wherein
the non-infrared ray-shielding layer (C) comprises a polymer (C-2) having carboxylate groups and ester bond groups in a molecule thereof and an infrared ray absorber (C-3),
the ester bond groups contained in the polymer (C-2) have a saturated hydrocarbon chain of 2 to 8 carbon atoms, and
the polymer (C-2) comprises a structure in which a carbon bonded to one of the carboxylate groups is adjacent to a carbon bonded to one of the ester bond groups, and a proportion of the adjacent bonds relative to all ester bond groups contained in the polymer (C-2) is 15% or more.
