<P>PROBLEM TO BE SOLVED: To provide a lithographic printing plate precursor and its laminate that suppress adhesion and rub scratches between the surface of the lithographic printing plate precursor and the backside of a support in an adjacent lithographic printing plate precursor when the plates are stacked without using inserting paper, that suppress polymerization inhibition in a polymerizable negative photosensitive layer, and that prevent fracture of the photosensitive layer. <P>SOLUTION: The lithographic printing plate precursor has a polymerizable negative photosensitive layer and an oxygen blocking layer containing mica sequentially in this order on a support, and further has a protective layer containing fine particles containing an organic resin as the uppermost layer, wherein the hardness H<SB>1</SB>of the fine particles containing the organic resin and the hardness H<SB>2</SB>of the oxygen blocking layer containing mica satisfy the relation of H<SB>1</SB>≤H<SB>2</SB>. <P>COPYRIGHT: (C)2008,JPO&INPIT |
