A lithographic printing plate precursor is disclosed,ncomprising a hydrophilic support having thereon a heat-sensitivenlayer containing either a microcapsule containingna compound having a functional group capable of reacting bynheat or a fine particulate polymer, wherein (1) when thenheat-sensitive layer contains a fine particulate polymer,nthe fine particulate polymer may be a fine particulatenpolymer capable of combining or incapable of combining bynheat used for the image formation and the fine particulatenpolymer has a functional group capable of reacting with anfunctional group present in another fine particulatenpolymer or with a functional group present in anotherncomponent in the heat-sensitive layer; or (2) when thenheat-sensitive layer contains a microcapsule containing ancompound having a functional group capable of reacting bynheat, the microcapsule may be a microcapsule having annouter wall capable of rupturing or incapable of rupturingnby heat used for the image formation and a light-to-heatnconverting material is contained in the heat-sensitivenlayer or in a layer adjacent thereto. |
