PORPHIN TYPE RECORDING MATERIAL

摘要

PURPOSE:To obtain the diazo type recording material small in the half value of each of generated holes by using a nonionic porphin as a guest component and an organic polymer having hydrogen atoms replacd by deuterium atoms as a host component. CONSTITUTION:This porphin type recording material is composed essentially of the guest component of the nonionic porphin derivative and the host component of the organic polymer compatible with the guest component and having the hydrogen atoms replaced by deuterium atoms. The guest component can be used without any limit so long as it is a nonionic porphin derivative soluble in general organic solvents and the especially preferably used derivative is represented by formula in which each of X1-X4 is an aryl or heterocyclic group.
