Abstract: An ink-receiving material comprising a support coated on at least one side with an ink-receiving layer, the ink-receiving layer containing silica with a primary particle size between 7 and 40 nm and an at least partially hydrolyzed copolymer comprising vinyl ester and ethylenically unsaturated cationic monomer units hardened with boric acid or a borate, wherein said ethylenically unsaturated cationic monomer units is a quaternary ammonium salt or a quaternary phosphonium salt and said quaternary ammonium salt is an N,N-dialkenyl-N,N-dialkyl-ammonium salt; and a process for the preparation of an ink-receiving material comprising the steps of: coating a support on at least one side with a dispersion containing sub-micron silica particles, an at least partially hydrolyzed copolymer comprising vinyl ester monomer units, ethylenically unsaturated cationic monomer units and boric acid or a borate, thereby preparing an ink-receiving layer hardened with boric acid or a borate, wherein said ethylenically unsaturated cationic monomer units is a quaternary ammonium salt or a quaternary phosphonium salt and said quaternary ammonium salt is an N,N-dialkenyl-N,N-dialkyl-ammonium salt.
