Summary:A dry planographic printing plate suitable for use in commercial web offset printing and newspaper web offset printing includes a photosensitive layer and a silicone rubber layer both laminated successively onto a base substrate. The photosensitive layer contains a diamine derivative represented by the following general formula (1): in which R1, R2, R3 and R4 are each independently hydrogen or a hydrocarbon, substituted hydrocarbon, acyl or substituted acyl, group having 1 to 20 carbon atoms, R5 and R6 are each independently hydrogen or an alkyl group having 1 to 20 carbon atoms and any of the groups R5 and R6 is optionally alternatively bonded to either of the methylene groups remote from the oxygen (as shown in formula 1), or adjacent the oxygen, in the ether chain, and n is 1 to 50.
