ABSTRACT A marking structure for various uses, such as in hand stamps or other printing members, or in ink pads, ink rolls or other inking members. The marking structure is characterized by at least two layers, including an outer layer and an underlying reservoir layer. The outer layer has interconnected aggregates of thermoplastic resin, forming a microporous network of pores, and a marking fluid contained within the network. The reservoir layer has an open-pored macropourous structure, such as an open- cell polyurethane foam, impregnated with a microporous thermo- plastic resin, in the form of interconnected aggregates, and an additional amount of the marking fluid, The resin aggregates of the outer reservoir layers are joined at the interface of the layers to form a cohesive structure.
