Patent ID: 7910286

Claim:
A packaged body of lithographic printing plate precursors, which comprises at least two lithographic printing plate precursors free from interleaving sheets, each lithographic printing plate precursor comprising: an aluminum support; an image-recording layer; and a protective layer in this order, wherein a first one and a second one of the at least two lithographic printing plate precursors are laminated so that a surface of a side having an image-recording layer of the first one directly contacts with a surface of a side not having an image-recording layer of the second one, wherein no interleaving sheet is present between the at least two lithographic printing plate precursors, wherein the protective layer comprises an inorganic layered compound, wherein the image-recording layer comprises (A) an actinic ray absorber, (B) a polymerization initiator and (C) a polymerizable compound, wherein the at least two lithographic printing plate precursors each has an outermost surface having a center line average surface roughness (Ra) of from 0.2 to 0.6 μm in a side having an image-recording layer, and wherein the inorganic layered compound is a mica group consisting of natural mica and synthetic mica represented by the following formula: A(B,C) 2-5 D 4 O 10 (OH,F,O) 2 , wherein A is any of K, Na and Ca, B and C are any of Fe(II), Fe(III), Mn, Al, Mg and V, and D is Si or Al.
