    Abstract: The invention relates to a partially cross-linked polyvinyl alcohol, obtained by reacting a polyvinyl alcohol with a polycarboxylic acid, in particular a hydroxypolycarboxylic acid. The partially cross-linked polyvinyl alcohol can be used to produce foils, which have a good water-solubility or water-swelling capacity. Due to this property, such foils can be used as packing material for detergents, cosmetics and the like. According to the invention, the packing dissolves in water, releases its contents or is suitable for releasing (permeation) chemical compounds or agents.

    Abstract: Use of finely divided aqueous cationic dispersions of synthetic resins obtainable by emulsion polymerization from suitable monomers and which contain cationic dispersion polymers, as impregnants and primers for consolidating and priming of porous absorbent substrates, preferably inorganic substrates such as, for example, masonry, concrete, plaster surfaces, gypsum surfaces, bricks or wood, by treating these substrates with the aqueous cationic dispersions whose polymer particles have mean particle diameters of 0.02 to 0.2 .mu.m.Aqueous cationic dispersions of synthetic resins exhibit a superior penetrating and permeating power, in particular on smooth plaster surfaces and smooth gypsum surfaces, compared with aqueous anionic or non-ionic dispersions of synthetic resins. Moreover they have no tendency to foam formation and can, in contrast to aqueous anionic or non-ionic dispersions of synthetic resins, exhibit a sealing action against staining, water-soluble substances, such as tarry products (tobacco smoke), resins, wood constituents (tanning) and dyes, which is of particular advantage for example in the building trade in the renovation of old buildings.
