摘要：
The invention concerns a writing implement (1) comprising ink (5) in a fibrous or non-fibrous reservoir, a retarding agent soluble or dispersible in the ink and a nib (7) for transferring ink (5) from the reservoir to the writing medium and a method for making such a nib (7). The invention is characterised in that a retarding agent is included in the writing nib (7) and is adapted to be carried by the ink (5) when it is transferred into said nib (7). The inventive method consists in impregnating an already machined writing nib with a solution containing a specific amount of a retarding agent, drying the impregnated writing nib, without stirring, by heating at a temperature less than 60null C.
