| abstract |
A photosensitive recording material is described with a support, a photosensitive layer which contains a diazonium salt polycondensation product, a free-radically polymerizable compound, a photoinitiator and a polymeric binder, and a cover layer which contains a water-soluble polymer which is not permeable to atmospheric oxygen and a water-soluble acidic phosphate , in particular a primary ammonium, sodium or potassium phosphate. The material is characterized by high sensitivity to light, good shelf life and low tendency to stick. It is particularly suitable for the production of planographic printing plates with a high circulation output. |
