Latest Patents
One of his latest patents focuses on dyeing preparations and their use for preparing developing dyes. This innovation allows for the production of developing dyes using preparations that contain molar amounts of diazo or coupling components in simple numerical ratios. The stability of these preparations, which utilize finely dispersed amines, enables the reaction of stoichiometric amounts, leading to multicolor effects that were previously difficult to achieve. Another significant patent involves a process for printing mixed fabrics of polyester and cellulose. This process utilizes printing pastes containing coupling components dissolved in an alkaline medium, along with diazotizable primary aromatic amines. The method ensures that the amines are practically non-volatile at drying temperatures, allowing for the effective development of water-insoluble azo dyestuffs on the fibers.
