Title: Ulrich Schadeli: Innovator in High Molecular Weight Materials
Introduction
Ulrich Schadeli is a notable inventor based in Plasselb, Switzerland. He has made significant contributions to the field of high molecular weight materials, holding a total of 11 patents. His work focuses on developing innovative materials that have practical applications in various industries.
Latest Patents
One of Schadeli's latest patents is for a highly transparent, color-pigmented high molecular weight material. This invention relates to a color-pigmented organic material structured from a radiation-sensitive precursor by irradiation. The pigmentation consists of extremely fine particles, with at least 80 mol % of the pigmentation derived from specific pigment classes, including diketopyrrolopyrrole and dioxazine. These materials are designed to be used in thin layers on transparent substrates, serving as optical color filters. Another significant patent involves a wet-chemical, developable, etch-stable photoresist for UV radiation. This photoresist composition is transparent in its solvent-free state and contains nonaromatic chemical groups that can be converted into latent aromatic groups under specific process conditions. The resist coatings produced with these compositions exhibit stability in plasma etching comparable to conventional resists based on phenolic resins.
