Title: Imaging element for making lithographic printing plates with a decreased slippage in the press

Abstract: According to the present invention there is provided an imaging element for making a lithographic printing plate, including on a first side of a flexible support a surface capable of being differentiated in oleophilic and oleophobic areas upon imaging and on a second side opposite to the first side a layer or a package of layers, characterized in that the layer or package of layers on the backside has a ratio of the squared value of the gravimetric water absorption (WA) in g/m.sup.2 over the mean roughness in .mu.m greater than 20.
