Title: Victor J Thijs: Innovator in Photographic Coatings
Introduction
Victor J Thijs was a notable inventor known for his contributions to the field of photographic materials. He was based in Berchem, Belgium, and his work has left a lasting impact on the industry. Thijs is remembered for his innovative approach to creating hydrophilic coating compositions that enhance photographic surfaces.
Latest Patents
Thijs held a patent for "Photographic matt layers or surfaces." This invention involves hydrophilic coating compositions made from a protective colloid and a dispersed matting agent. The matting agent is created by mixing formaldehyde and an aqueous colloidal dispersion of silica in an aqueous medium. The mixture is carefully buffered to maintain a pH of 3.2 or lower. Urea and formaldehyde undergo polycondensation while being vigorously stirred until particles of urea-formaldehyde resin and silica are formed, with an average particle size of 1-8 µm. The stirring rate is then reduced, and the pH is increased to 5 or higher to prevent further polycondensation and agglomeration of the polymer particles. Finally, a hydrophilic colloid is dissolved in the reaction mixture, resulting in a photographic light-sensitive silver halide material that incorporates a layer formed from the hydrophilic coating composition.
Career Highlights
Throughout his career, Thijs made significant advancements in the field of photographic technology. His innovative methods and formulations contributed to the development of improved photographic materials, which were essential for the industry.
Collaborations
Thijs collaborated with several professionals during his career, including Paul E Huyghebaert, an administrator, and Nikolaas C De Jaeger. These collaborations helped to enhance the quality and effectiveness of his inventions.
Conclusion
Victor J Thijs was a pioneering inventor whose work in photographic coatings has had a lasting influence on the industry. His innovative patent for hydrophilic coating compositions showcases his dedication to advancing photographic technology.
