Abstract
Process for preparing dispersions stabilized with protective colloid using sulfonato-containing polyvinyl acetals as the protective colloid in the preparation of the dispersions, if desired in combination with additional emulsifiers or additional protective colloids. The dispersions exhibit a pH-dependent viscosity and are suitable, for example, for coating and bonding substrates and as rheology modifiers and binders and for use in solid paints.
