    Abstract: The invention relates to a water-borne hybrid binder composition. It is obtained by mixing about 20-80 % by weight of A), an aqueous dispersion of a polymer, said dispersion having a dry-solids content of at least 45 % by weight, and containing at least 0.1 % by weight of B) a single surfactant or a mixture of two or more different surfactants and protective colloids, and about 80-20 % of C) one or more resins being emulsifiable in water and having a dry solids content abov e 90 % by weight, by adding the resin C to the dispersion A under agitation, the resulting hybrid binder composition obtaining a dry- solids content of 60-95 % by weight. The invention also relates to the use of the binder composition as a component in a paint or lacquer mixture.

    Abstract: Binder for a pressure sensitive adhesive, characterized in that it exists as a polymer dispersed in water and obtained by emulsion polymerization of: (A) 65.0-99.4 percent by weight of one or more acrylic esters with 4-18, preferably 6-10 carbon atoms in the alcohol part of the ester, the esters being selected in such a way that a polymerization of only these esters gives a tacky polymer with a Tg-value below 0 DEG C., preferably below -20 DEG C. (B) 2.0-0.1 percent by weight of a polymerizable compound with the formula or with the formula wherein R1, R2, R3 and R4 are as defined in the specification (C) 5.0-0.5 percent by weight of at least one ethylenically unsaturated acid such as acrylic acid, methacrylic acid or itaconic acid and (D) 28.0-0 percent by weight of one or more compounds selected from the group consisting of alkyl- or hydroxyalkyl acrylate or a lower alkyl or hydroxyalkyl methacrylate with 1-3 carbon atoms in the alcohol part of the ester, acrylonitrile or styrene.
