Abstract: An acrylate copolymer for use in pressure-sensitive adhesives, particularly suitable for the bonding of low-energy surfaces, is composed of the following monomer components: A) 60 to 95% by weight of one or more monomers selected from alkyl acrylates and alkyl methacrylates, the alkyl containing 1 to 10 carbon atoms; B) 5 to 15% by weight of one or more monomers selected from esters of (meth)acrylic acid with a polyethylene glycol derivative having from 2 to 4 ethylene glycol units, the (meth)acrylic esters being free from hydroxyl groups; and C) 1 to 35% by weight of a mixture of at least two vinyl compounds selected from vinyl compounds which contain one or more of the following functional groups: free carbonyl groups, free carboxyl groups, groups having one or more active hydrogen atoms.

Abstract: A medical pressure sensitive adhesive mass having a moisture vapor transmission of at least 10,000 g/m.sup.2 /24.h (measured with a pressure sensitive adhesive film having a weight of 30 g/m.sup.2) and an excellent adhesion to both dry skin and that is moist due to perspiration, comprising:A) a copolymer synthesized from components comprising:1) 50 to 95%-wt., preferably 70 to 90%-wt., based on the weight of the copolymer, of one or several alkyl esters of acrylic and/or methacrylic acid have 4 to 12 C-atoms in the alkyl residue; and2) 5 to 50%-wt., preferably 10 to 30%-wt., based on the weight of the copolymer, of a vinylcarboxylic acid,B) 25 to 90%-wt., preferably 50 to 80%-wt., of a hydrophilic emulsifier comprising tertiary or quaternary ammonium groups,C) 15 to 60%-wt., preferably 20 to 40%-wt., of a hydrophilic polyoxyalkylene groups-containing emulsifier which is free from amino groups,D) 1 to 20%-wt., preferably 3 to 15%-wt., of a polyvinylcarboxylic acid,E) 1 to 15%-wt., preferably 3 to 10%-wt.

Abstract: A medical patch material has a support coated with an even and porous spread of pressure sensitive hot-melt adhesive coating, formed by means of gravure printing, has a sufficient porosity and a resulting vapor permeability to skin moisture on the one hand, as well as an absolute bacteria-impermeability and reliable adherence of the patch material on the other hand. This is achieved by the fact that the pressure sensitive hot-melt adhesive spread:a) forms coherent webs in the lengthwise and transverse direction, which include island-shaped adhesive-free areas;b) that the proportion of the adhesive-free areas amounts to between 30 and 60%, preferably between 40 and 57% of the total surface, andc) that the coat weight of the adhesive amounts to between 30 and 160 g/m.sup.2, preferably between 40 and 120 g/m.sup.2.

Abstract: The invention relates to plasters, particularly epicutaneous test plasters with at least one active substance absorbing or receiving device (14) arranged on a carrier film (32). The carrier film (12) is made from a highly elastic polymer material, which is impermeable for liquid water, but permeable for water vapour. On the surface remote from the skin, it is detachably connected in whole-area or partial area manner with a support film (11) at least covering the surface of the carrier film. The invention also relates to processes for the production thereof and the use thereof.
