| 摘要 |
Light-sensitive registration material with a layer base and a light-sensitive layer which essentially contains a diazonium salt polycondensation product, a water-insoluble polymeric binder which is soluble in organic solvents and is soluble, or at least swellable, in aqueous alkaline solutions, a polymerisation initiator which forms radicals on exposure to actinic radiation and a polymerisable, ethylenically unsaturated compound containing at least one unsaturated group and having a boiling point above 100 DEG C at normal pressure, characterised in that the registration material contains, between the light-sensitive layer and the layer base, a light-sensitive intermediate layer which essentially contains a diazonium salt polycondensation product and a water-insoluble polymeric binder which is soluble in organic solvents and is soluble, or at least swellable, in aqueous alkaline solvents. |
