ELEMENT INCLUDING A LAYER CONTAINING AROMATIC O-DIALDEHYDE DYE FORMER AND A RADIATION RESPONSIVE IMAGE-FORMING COMPOSITION AND A SUPERIMPOSED POLYMER 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. An imaging method is also disclosed.
