A premix capable of forming a microporous marking structure is prepared by kneading a pouch containing the premix, then opening the pouch and removing the premix therefrom. The mixed premix is then typically poured in a mold, and an absorbent backing layer is placed on the premix. The premix is then heated to form a microporous structure, and then cooled. The dispensing package used in this method is a thin-walled, flexible pouch which contains the premix. This dispensing pouch can eliminate the need to make up a batch of premix immediately prior to casting, together with the need to measure the amount of premix needed for each casting.

Package for dispensing a fluid containing an ink

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.
