Abstract
Official abstract text for this publication.
Release coatings on cellulosic substrates such as paper or cardboard, having high mechanical properties, are produced by coating with a polyvinyl alcohol containing ethylenic unsaturation and a silicone crosslinking agent and a silicone containing ethylenic unsaturation.
First claim
Opening claim text (preview).
1 .- 10 . (canceled) 11 . An impregnation agent, obtained by a process comprising reacting polyvinyl alcohol containing olefinic C—C double bonds with a silane-group-containing cross-linking agent and a silicone compound that contains olefinic C—C double bonds. 12 . The impregnation agent of claim 11 , wherein the polyvinyl alcohol contains olefinic C—C double bonds in a main chain of the polyvinyl alcohol. 13 . The impregnation agent of claim 11 , wherein compounds of the Formula I are used as a polyvinyl alcohol containing olefinic C—C double bonds with n=100-3000. 14 . The impregnation agent of claim 11 , wherein the polyvinyl alcohol contains olefinic C—C double bonds in side chains. 15 . The impregnation agent of claim 11 , wherein compounds of the Formula II are used as silane-group-containing cross-linking agents 16 . The impregnation agent of claim 11 , wherein compound of Formula III is used as a silicone compound containing olefinic C—C double bonds: 17 . A method for impregnating cellulose-based materials, comprising: applying an impregnation agent, obtained by reacting at least one polyvinyl alcohol containing olefinic C—C double bonds with a silane-group-containing cross-linking agent and a silicone compound that contains olefinic C—C double bonds. 18 . The method of claim 17 , wherein at least one polyvinyl alcohol containing olefinic C—C double bonds is applied to a cellulose-based material, and is then reacted with a silane-group-containing cross-linking agent and a silicone compound that contains olefinic C—C double bonds. 19 . The method of claim 17 , wherein the reaction is catalysed by platinum, palladium, or rhodium salts or complexes. 20 . The method of claims 17 , wherein paper or cardboard is used as cellulose-based material.
