ABSTRACT:
Aqueous dispersions of polymers containing (meth)acrylic acid alkyl ester units which contain the polymer in the form of relatively large, non-agglomerated, spherical particles (=main spheres) and relatively small, non-agglomerated, spherical particles (=filler spheres), wherein the smaller filler spheres have an average particle diameter d.sub.F measured using an electron microscope of from 50 to 150 nanometers (nm) and the average diameter of the large main spheres d.sub.H is from 1.35 to 3.5 times larger than the average particle diameter d.sub.F, provided that d.sub.H is at least 140 nm, and wherein the ratio of the total mass of the polymer composed of main spheres M.sub.H to the total mass of the polymer composed of filler spheres M.sub.F is
