    摘要： A lithographic printing plate precursor includes an image recording layer on a support, in which the lithographic printing plate precursor has projections which are discontinuously formed on a surface of an outermost layer on a side where the image recording layer is provided, and a melting point of each projection is in a range of 70° C. to 150° C.
    A method of producing a lithographic printing plate includes a step of image-wise exposing the lithographic printing plate precursor to form an exposed portion and an unexposed portion, and a step of supplying at least one of printing ink or dampening water to remove the unexposed portion.

    摘要： An object of the present invention is to provide a water-developable flexographic printing plate precursor which has excellent water developability and exhibits excellent printing durability in a case of being made into a flexographic printing plate, a flexographic printing plate, and a photosensitive resin composition. The water-developable flexographic printing plate precursor of the present invention includes a photosensitive layer, in which the photosensitive layer contains a monomer, a polymerization initiator, a base polymer, and water-dispersible particles, the water-dispersible particles have carbon-carbon double bonds, and an amount of the carbon-carbon double bonds on a surface of the water-dispersible particles is 21 or less.

    摘要： Provided is a lithographic printing plate precursor having: a support; and an image-recording layer as an outermost surface layer on the support, in which the image-recording layer includes a hydrophilic polymer, an ion intensity derived from the hydrophilic polymer has a maximum value I1, the ion intensity being measured by a time-of-flight secondary ion mass spectrometry in such a manner that cutting is carried out from an image-recording layer surface in a direction of the support by an Ar gas cluster ion beam method, a ratio d0/d1 of a thickness d0 of the image-recording layer to a depth d1 from an outermost layer at which the I1 is obtained is 2.0 or more, and a ratio I1/I0 of the I1 to an ion intensity I0 derived from the hydrophilic polymer at a depth from the outermost layer of the d0 is 1.5 or more.
