An improved microporous marking structure has a layer of a microporous material containing a marking fluid and an absorbent backing layer superposed thereon which shortens processing time by absorbing excess marking fluid from the microporous layer. The marking structure according to the invention may be advantageously used to make a self-inking hand stamp. No lengthy step for removing excess ink from the microporous layer is needed.
