Latest Patents

Sikora’s recent patents showcase her expertise in developing advanced photosensitive transfer materials. One of her notable inventions is a photosensitive transfer material that utilizes a support with defined roughness. This invention includes a flexible temporary support film, preferably transparent, combined with a thermoplastic photosensitive layer. The flexible cover film and optional intermediate layer between the support film and the photosensitive layer contribute to the material's unique properties. The rough surface creates an embossing effect on the photosensitive layer, while a matte finish on the intermediate layer reduces irregular deformation in moist air, effectively preventing unwanted reflections.

Another significant patent pertains to a radiation-polymerizable mixture and photopolymerizable copying material. This mixture incorporates a compound featuring at least two terminal ethylenically unsaturated groups, capable of forming a crosslinked polymer via free-radical initiated addition polymerization. This development represents a valuable advancement in flexible transparent temporary support systems with a transferable thermoplastic photopolymerizable layer.
