Latest Patents

Melz's latest patents focus on a light-sensitive, color photographic silver halide multilayer material. This innovative material includes DIR-couplers that are substituted in the coupling position by mercapto-azole, mercaptobenz-azole, or mercapto-azine moieties, which carry hydrophilic substituents. These DIR-couplers can be utilized alongside other couplers and additives or as the sole color-forming element. They are recognized for their high color yields and inter- and intra-image effects. The couplers can be added in both hydrophobic (dispersed form) and hydrophilic (alkaline solutions) states. Furthermore, they can be employed in single layers or as associated layers, with a maximum of three layers of a color-forming unit, arranged in any desired order within the overall combination of layers.
