A negative type photosensitive resin composition includes a polymer compound which has, in a main chain thereof, a constitutional unit A represented by Formula A-1, a constitutional unit B that is at least one of constitutional units represented by Formulae B-1, B-2, B-3, B-4, B-5, B-6, or B-7, and a constitutional unit C containing an ethylenically unsaturated group; and a polymerization initiator.
A negative type planographic printing plate precursor includes an image recording layer containing the negative type photosensitive resin composition.
A method of preparing a planographic printing plate includes, in order, an exposure step of image-exposing the negative type planographic printing plate precursor; and a development step of performing development by removing a non-exposed portion of the exposed negative type planographic printing plate precursor using a developer.
