摘要：
The present invention provides an imaging element comprising on a support in the order given, a hydrophilic layer containing a hydrophilic (co)polymer or (co)polymer mixture and being hardened with a hydrolyzed tetraalkyl orthosilicate crosslinking agent and a light sensitive layer containing a diazo resin or a diazonium salt characterized in that an intermediate hydrophilic layer containing an organic compound having one or more cationic groups is provided between said hydrophilic layer and said light-sensitive layer. There is further provided a method for making such an imaging element and a method for making a lithographic printing plate therewith.
