Claims
- 1. An imaging element having a flexible support and comprising on said support a photosensitive layer comprising a silver halide emulsion and an image-receiving layer comprising physical development nuclei, said layers being in water permeable contact with each other, characterized in that said flexible support is a biaxially oriented polyester film having Young-moduli of at least 9500N/mm.sup.2 at least one of said Young-moduli being at least 5100N/mm.sup.2, and a thickness between 0.15 mm and 0.35 mm and consisting of polyethylene 2,6-naphthalenedicarboxylate.
- 2. An imaging element according to claim 1 wherein said polyester film support has a thickness between 0.20 mm and 0.30 mm.
- 3. An imaging element according to claim 1 wherein in said polyester film the ratio of the Young-modulus in longitudinal direction to Young-modulus in the transverse direction is between 0.8 and 1.2.
- 4. An imaging element according to claim 1 comprising on a support in the order given a photosensitive layer comprising a silver halide emulsion and an image-receiving layer comprising physical development nuclei, said layers being in waterpermeable contact with each other.
- 5. An imaging element according to claim 1 comprising on a hydrophilic surface of a support in the order given an image-receiving layer comprising physical development nuclei and a photosensitive layer comprising a silver halide emulsion, said layers being in waterpermeable contact with each other.
- 6. A method for making a lithographic printing plate comprising the steps of image-wise exposing an imaging element according to claim 1 and subsequently developing a thus obtained imaging element by an alkaline processing liquid in the presence of developing agent(s) and silver halide solvent(s).
