Abstract
Provided are a planographic printing plate precursor including: a support; and an image recording layer provided on the support, in which the image recording layer contains an infrared absorbing agent, a polymerization initiator, a polymerizable compound containing a hydrogen bonding group, and a hard polymer particle containing at least one group selected from the group consisting of a urethane group, a urea group, an imide group, an amide group, and a sulfonamide group on the surface of the hard polymer particle, and a number average primary particle diameter of the hard polymer particle is in a range of 0.01 to 1 μm; and a plate-making method for a planographic printing plate obtained by using the planographic printing plate precursor.
