    Abstract: The invention relates to a contact adhesive comprising a mixture of two polymers P1 and P2 formed of two radically polymerizable monomers, wherein P1 is formed of a first main monomer M1 at at least 50 wt %, comprising, when polymerized as a homopolymer, a glass transition temperature of less than 0°C, and wherein P2 is formed of a second main monomer M2 at at least 50 wt %, comprising, when polymerized as a homopolymer, a glass transition temperature of less than 0°C, and being different from M1. P2 is otherwise formed by M1. The polymerization of P2 takes place by stage polymerization, wherein a monomer composition comprising M2 is polymerized in a first stage, and a monomer composition comprising M1 is polymerized in a second stage.

    Abstract: The present invention relates to aqueous polymer dispersions having a polymer content of at least 55 wt.-%, said dispersions being suitable for adhesives. The invention also relates to a method for producing said aqueous polymer dispersions and the use of the aqueous polymer dispersions in adhesives or adhesive compositions, especially in adhesives for transparent substrates such as plastic labels. The aqueous polymer dispersions have a polymer content of at least 55 wt.-% relative to the total weight of the dispersion, wherein the polymer is made up of ethylenically unsaturated monomers M and has a glass transition temperature of less than -10°C, wherein the dispersed polymer particles have a polymodal particle size distribution, wherein at least 70 wt.-%, preferably at least 75 wt.-%, in particular at least 80 wt.%, especially preferably at least 85 or at least 90 wt.-% of the polymer particles have a particle diameter of less than 350 nm, in particular less than 340 nm, especially less than 330 nm.
