Title: Marcel Mestdagh: Innovator in Photographic Materials
Introduction
Marcel Mestdagh is a notable inventor based in Rymenam, Belgium. He has made significant contributions to the field of photographic materials, particularly through his innovative methods in the production of silver halide grains.
Latest Patents
Mestdagh holds a patent for a method of making tabular silver halide grains. This photographic material is characterized by a coating on at least one side of a support with a photosensitive layer containing hexagonal and/or circular tabular silver halide emulsion crystals. These crystals occupy at least 70% of the total projected area of all grains, with a thickness ranging from 0.15 to 0.30 µm. The method ensures that the coefficient of variation of the tabular grains is between 0.15 and 0.45, and the average aspect ratio is at least 2:1. Notably, this process is conducted in the absence of ammonia, optimizing the use of silver nitrate during the growth steps.
Career Highlights
Mestdagh is associated with Agfa Gevaert NV, a company renowned for its advancements in imaging technology. His work has contributed to the development of high-quality photographic materials that maintain sensitivity and gradation even after being developed in diluted, cost-effective developers.
Collaborations
Mestdagh has collaborated with Marc Van Den Zegel, further enhancing the innovative efforts within the company.
Conclusion
Marcel Mestdagh's contributions to the field of photographic materials through his patented methods exemplify the importance of innovation in technology. His work continues to influence the industry, ensuring the production of high-quality photographic materials.
