    Abstract: PROBLEM TO BE SOLVED: To provide a composition that can be used as a UVcrosslinkable adhesive. SOLUTION: This composition comprises a polyacrylate prepared for melt processing and a stabilizer having at least one phosphorous group. The acrylate preferably comprises >=60 mass % of acrylic monomer, has a glass transition point of -55 deg.Cto -10 deg.C, can be crosslinked with UV rays, has the K-value of 30-80 measured in tetrahydrofuran (1% solution at 21 deg.C). The resultant composition is suitable as a hot-melt adhesive that can be used in labels, adhesive tape, sheets and the like.

    Abstract: The invention relates to the use of radically polymerized polymers which can be cross-linked by UV light, comprising at least 50 wt. % C2 - C18 alkyl(meth)acrylates, as an adhesive for glueing carriers coated with said polymer on substrates. The invention is characterized in that 0,1 -30 wt. % of the monomers which make up said polymer are monomers A without carboxylic acid or carboxylic acid anhydride groups with a water solubility which is greater than 5g monomers/ litre of water. The carriers are can be removed.

    Abstract: The invention relates to a method for producing an aqueous polymer dispersion having a polymer solids content of >=50% by weight by carrying out the radically initiated aqueous emulsion polymerization of ethylenically unsaturated compounds (monomers). The inventive method is characterized in that: a) a mixture is provided in a polymerization vessel and contains a partial quantity 1 consisting of: deionized water, 0.001 to 0.5 parts by weight of a polymer with a weighted average particle diameter of =80% [polymerization step A], and; b) afterwards, a monomer emulsion containing partial quantity 2, which consists of deionized water, 0.1 to 5 parts by weight of dispersants and 90 to 99.5 parts by weight of monomers, is fed under polymerization conditions to the obtained reaction mixture [polymerization step B], whereby; c) the total amount of the monomers used for the polymerization is equal to 100 parts by weight, and the total amount of deionized water is
