Abstract
A direct drawing type lithographic printing plate precursor comprising a water-resistant support having provided thereon, an image-receiving layer comprising inorganic particles and a binder resin. The combination of an inorganic particles is made up of at least one kind of metal sulfide particle having an average particle size of sum 0.01 to 5 μm and at least one kind of particle which may be a metal oxide particle having an average particle size of sum 0.01 to 5 μm or a metal oxide hydrate having an average particle size of 0.01 to 5 μm. The binder resin is a complex composed of a resin containing a siloxane bond.

A direct drawing type lithographic printing plate precursor comprising a water-resistant support having provided thereon an image-receivinq layer comprising inorganic particles and a binder resin, wherein the inorganic particles comprise a combination of metal sulfide particles and metal oxide hydrate particles and
- wherein metal sulfide particles have an average particle size of from 0.01 to 5 μm and comprise a metal atom selected from Zn, Ag, Se, Fe, Pb, Sb, Cd, Cr, Co, Zr, Sn, Ti, Ni, Mg, Mo, La, Pd, Y, In and Ir;
- and the metal oxide hydrate particles have an average particle size of from 0.01 to 5 μm and comprising a metal atom selected from Mg, Al, Zn, Ge, Co, Zr, Sn, Fe, Cu, Ni, Pb, Ti, Pd, Cd, Cr, Ga, Mn, V, Mo, Ce and La;
- in a weight ratio of the metal sulfide particles/metal oxide hydrate particles is from 5/95 to 50/50, and
- wherein the binder resin comprises a complex composed of a resin containing a siloxane bond in which a silicon atom is connected with an oxygen atom and an organic polymer containing a group capable of forming a hydrogen bond with the resin containing a siloxane bond.
