An acceptor material (10) for printing by ink-jet printers forms quick-drying, water-soluble resistant, light-stable ink records with aqueous ink jet inks. The material (10) comprises a support (12) such as polyester film and a coated layer (14) containing a water-soluble mordant that forms insoluble compounds with and immobilizes the dyes of the ink jet inks and a hardened water managing polymer, preferably. hardened gelatin, which contains polymeric beads in an uppermost layer. The water-soluble mordants can high molecular quaternary ammonium, amino compounds, phospholipids, or divalent Group II metal ions.

Un matériau accepteur (10) destiné à l'impression à l'aide d'imprimantes à jet d'encre permet la formation d'images et d'informations à base d'encre stable à la lumière, résistante, soluble dans l'eau, et séchant rapidement, et appliquée sous forme de jets d'encre aqueux. Le matériau (10) comprend un support (12) tel qu'un film polyester et une couche déposée (14) contenant un mordant soluble dans l'eau qui forme des composés insolubles avec les colorants des encres et qui immobilise ceux-ci, et un polymère durci absorbant l'eau, de préférence la gélatine durcie, qui contient des billes polymères dans une couche supérieure. Les mordants solubles dans l'eau peuvent être un ammonium quaternaire de masse moléculaire élevée, des composés amino, des phospholipides ou des ions métalliques divalents du groupe II.
