Title: Rudolf Kostka: Innovator in Coupling Components
Introduction
Rudolf Kostka is a notable inventor based in Munich, Germany. He has made significant contributions to the field of chemistry, particularly in the development of concentrated solutions of water-insoluble coupling components. With a total of 2 patents, his work has implications for various applications, including dyeing techniques.
Latest Patents
Kostka's latest patents focus on concentrated solutions of water-insoluble bis-acetoacetic acid-diphenylamides as coupling components. These solutions are designed to contain water, sodium and/or potassium hydroxide, and aliphatic solvents such as mono- or di- to hexa-ethyleneglycol monoalkyl ethers. The solutions can achieve a concentration of up to about 50% by weight without compromising their storage stability. They are particularly useful for preparing water-insoluble azo dyestuffs on fibers, facilitating the 'ice-color' dyeing process. Upon mixing with water containing a small amount of sodium hydroxide, these solutions create ready-to-use impregnation baths. Additionally, he has developed highly concentrated solutions that maintain excellent stability for the preparation of diluted aqueous bottoming baths in the ice-color dyeing technique.
