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 above 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.degree. C., preferably below -20.degree. C.(B) 2.0-0.1 percent by weight of a polymerizable compound with the formula ##STR1## or with the formula wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 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 acidand(D) 28.
