    Abstract: The present invention provides aqueous polymer dispersions comprising at least one particulate polymer P having a glass transition temperature Tg of less than 0° C. which is composed of ethylenically unsaturated monomers M including:i. from 60 to 94.9% by weight, preferably from 75 to 89.5% by weight, of n-butyl acrylate as monomer M1,ii. from 5 to 39.9% by weight, preferably from 10 to 24.5% by weight, of at least one monomer M2 selected from esters of methacrylic acid with C1 to C4 alkanols, tert-butyl acrylate, and vinylaromatic monomers, andiii. from 0.1 to 5% by weight, preferably from 0.5 to 2% by weight, of at least one monomer M3 selected from ethylenically unsaturated compounds having at least one acid group;the proportions of said monomers M1 to M3 being based on 100% by weight of monomers M,obtainable by free-radical aqueous emulsion polymerization of monomers M in the presence of at least 0.01% by weight, based on the weight of the monomers M, of at least one molecular weight regulator. The present invention also provides for the use of such polymer dispersions in adhesive formulations for producing laminates, a process for producing laminates, and the laminates obtainable by this process.

    Abstract: Empleo de un adhesivo de recubrimiento, que contiene como agente aglutinante una mezcla formada por A) un polímero, que puede obtenerse mediante la polimerización de compuestos polimerizables por medio de radicales, y B) compuestos con un grupo etilénicamente insaturado, polimerizable por medio de radicales (en abreviatura grupo polimerizable) y con un peso molecular, promedio en peso, Mw menor que 5.000 g/mol, para el forrado con láminas de brillo, es decir para el pegado de láminas polímeras transparentes con papel o con cartón, o para el forrado de láminas compuestas, para envases, es decir para el pegado de láminas polímeras con otras láminas polímeras, con láminas metálicas o con láminas metalizadas.

    Abstract: The present invention relates to adhesives comprising at least one silicon-comprising copolymer of C 1 -C 20 -alkyl (meth)acrylates and at least one ethylenically unsaturated acid anhydride or one ethylenically unsaturated dicarboxylic acid whose carboxyl groups can form an anhydride group, or mixtures thereof, or at least one monomer comprising an isocyanate group and capable of free radical copolymerization.
