Title: Max Heilmann: Innovator in Photographic Chemistry
Introduction
Max Heilmann is a notable inventor based in Cologne, Germany. He has made significant contributions to the field of photographic chemistry, particularly in the development of color photographic processes. With a total of 2 patents, his work has had a lasting impact on the industry.
Latest Patents
Heilmann's latest patents include a "Photographic color developer mixture" and a "Process for bleach-fixing chromogenically color photographic silver." The first patent describes an aqueous alkaline developer mixture designed for preparing color photographic images. This mixture contains a color developer from the p-phenylenediamine series, a hydroxylamine compound, and a hydroxyalkylidenediphosphonic acid or its water-soluble salt. It also includes a compound from the aminopolyphosphonic acid or aminopolycarboxylic acid series, which enhances resistance to oxidation and chalk deposits while ensuring high stability in storage. The second patent outlines a process for developing color film of the silver halide emulsion type. This process involves a bleach-fixing bath treatment to remove the silver image, followed by an oxidizing bath that restores the lost color to the dyes. The oxidizing bath must contain an iron-III-complex of an amino polyacetic acid, such as the sodium salt of the iron-III-complex of ethylene diamine tetra-acetic acid.
