An ink-jet printing process containing the steps (a) and (b) in any order or simultaneously: (a) applying an ink by means of an ink printer to a localised region of substrate to form an image on the substrate; and (b) applying a fixing composition containing a liquid medium and a polymeric biguanide containing a repeat unit of Formula (1) or a salt thereof by means of an ink jet printer to localised region of the substrate: wherein: X and Y are the same or different and represent divalent organic linking groups; and characterised in that the localised regions referred to in steps (a) and (b) are substantially coextensive.
