Patent AT-E401352-T1: [Translated] USE OF AMINOFUNCTIONAL POLYVINYLACETALS IN PRINTING INK COMPOSITIONS

Polyvinyl acetals which contain acetal moieties derived by acetalizing polyvinyl alcohol with both aliphatic aldehydes or their derivatives and with amino- and/or ammonium-substituted aldehydes display exceptional substrate adhesion when used in printing ink as binders, allowing inks without adhesion promoters to be produced.
