Lithographic printing plate precursor and method for preparation thereof

A lithographic printing plate precursor comprising:

• a support;
• an image-recording layer which is capable of being removed with at least one of printing ink and dampening water and contains (A) an iced absorbing agent, (B) a polymerization initiator and (C) a polymerizable compound;
• and an overcoat layer, in this order, wherein the overcoat layer is formed by dying a water-dispersible polymer particle.
