摘要：
Negative-working lithographic printing plate precursor a negative-working imageable layer and an outermost water-soluble overcoat layer that is disposed directly on the negative-working imageable layer. The outermost water-soluble overcoat layer comprises: (1) one or more film-forming water-soluble polymeric binders, (2) organic wax particles, and (3) non-wax matte particles. The outermost water-soluble overcoat layer has a dry thickness (t) that is defined by the following equation (I): t=w/r wherein w is the dry coverage of the outermost water-soluble overcoat layer in g/m2, and r is 1 g/cm3. The organic wax particles have an average largest dimension D(wax) that is less than 0.9 of t (in μm), and the non-wax matte particles have an average largest dimension D(matte) that defined by the following equation (II): 1.5 times t≦̸D(matte)≦̸40 times t(in μm).
