To provide a printing plate precursor which can be directly made by laser engraving, which is suitable not only for use as a resin relief printing plate suitable for oil-based inks but also as a flexographic printing plate which is printed with a weak printing pressure. A hydrophilic polymer (A1) containing hydroxyethylene as a structural unit, a hydrophilic polymer (A2) other than (A1), an ethylenically unsaturated monomer (B), a polymerization initiator (C), and a plasticizer (D ), A crosslinkable resin composition for laser engraving.
