OVERCOATED PHOTOTHERMOGRAPHIC ELEMENT HAVING A DYE-PRECURSOR RETAINING LAYER |
摘要 |
An imaging element which relies upon an aromatic dialdehyde to produce a dye provides improved maximum neutral densities when certain polymers are superimposed over the element. Such polymers seal the element to reduce loss of the dialdehyde during development. |
