    Abstract: The invention provides a planographic printing plate precursor that is writable by laser exposure and is composed of a support, a photosensitive recording layer formed on the support, and a backcoat layer containing an epoxy resin, the backcoat layer being formed on the side of the support opposite to the photosensitive recording layer side; and a stack of the planographic printing plate precursors. According to the invention, scratches on the photosensitive recording side of the planographic printing plate precursor can be prevented when brought into contact with another planographic printing plate precursor in the stack without interleaving slip sheets, and productivity in a plate making process can be improved.
