Title: Reinhard J Sappok: Innovator in Ink Technology
Introduction
Reinhard J Sappok is a notable inventor based in Montclair, NJ (US). He has made significant contributions to the field of ink technology, holding a total of 3 patents. His work focuses on developing innovative ink compositions that enhance printing processes.
Latest Patents
One of Sappok's latest patents is titled "Dye-latex combinations and use in aqueous inks." This patent discloses an aqueous ink composition that incorporates an oil-soluble dye in a latex. The dye is dispersed in a fortified latex, which consists of a blend of a distinct dispersed phase and a soluble polymer phase. The soluble polymer typically has a weight-average molecular weight ranging from about 5,000 to about 20,000 and an acid number between 50 and 400. These novel ink compositions have proven to be particularly effective in gravure and flexographic ink applications.
Another significant patent is related to a "Pigment product." This innovation allows for the production of ink without flushing by creating both an emulsion of a selected organic liquid and water, along with an aqueous suspension of a pigment. The emulsion and pigment are mixed, facilitating the phase transfer of the pigment from the aqueous phase to the non-aqueous phase. The resulting mixture is concentrated and added to an ink mixing tank, where the remaining water is evaporated, and additional ingredients are incorporated to produce the final ink.
