Title: Innovations of Karl Roth: Pioneering Copper Phthalocyanine Pigments
Introduction
Karl Roth, an accomplished inventor based in Limburgerhof, Germany, has made significant contributions to the field of pigment technology. With a total of three patents to his name, Roth has focused primarily on the development of versatile and efficient pigments. His work has been instrumental in advancing the use of copper phthalocyanine pigments, which are known for their vibrant colors and excellent durability.
Latest Patents
Roth's latest patents include two innovative methods for preparing copper phthalocyanine pigments. The first patent details the "Preparation of copper phthalocyanine pigments of the beta-modification." This process involves grinding crude pigment in the presence of 1 to 10% by weight of an organic liquid at temperatures between 90°C and 140°C. The resulting pigments exhibit strong, transparent, and readily dispersible properties, making them ideal for use in printing inks with superior flow characteristics.
The second patent focuses on the "Preparation of readily dispersible pigment granules." In this method, Roth describes a process involving the dispersion of a gas that does not react with the aqueous pigment suspension. This gas is introduced in fine bubbles under essentially atmospheric pressure, and the resulting suspension is converted into pigment granules either by spray drying or through mechanical removal of the liquid, followed by the shaping and drying of the moist pigment cake.
