Abstract: The invention relates to a pressure-sensitive adhesive comprising at least one synthetic rubber based on at least one vinylaromatic (A) and on at least one diene (B) and comprising block copolymers or else mixtures of these with a structure A-B-A and/or (A-B) n and derivatives thereof, where n is an integer which is at least 2, A is a polymer block comprising at least one vinylaromatic and B is a polymer block comprising at least one diene, and the proportion of the synthetic rubbers in the entire composition of the pressure-sensitive adhesive is at most 45% by weight, at least one bio-based adhesive resin and/or adhesive-resin mixture based to an extent of at least 85% by weight on renewable raw materials and having a softening point of at least 80°C and at most 110°C and making up a proportion of at least 35% by weight to at most 64% by weight of the entire composition of the pressure-sensitive adhesive, and at least one bio-based soft resin and/or soft-resin mixture based to an extent of at least 85% by weight on renewable raw materials and making up a proportion of at least 1% by weight to at most 25% by weight of the entire composition of the pressure-sensitive adhesive, where the entire pressure-sensitive adhesive without solvent corresponds to 100% by weight.

Abstract: To adhesively bond eloxated aluminium to plastic, a product having at least one layer of a latently reactive adhesive film which has a thermoplastic component which has a melting point T(melting) such that 35°C ≤ T(melting) ≤ 90°C, in particular 40°C ≤ T(melting) ≤ 60°C, and contains functional groups which can react with isocyanate and an isocyanate-containing component which is dispersed in particulate form in the thermoplastic component and is essentially deactivated in the region of the particle surface, where the particles have a start temperature T(start) such that 40°C ≤ T(start) ≤100°C, in particular 45°C ≤ T(start) ≤ 90°C, particularly preferably 45°C ≤T(start) ≤ 75°C; where T(start) ≤ T(melting), is used. Laminates of eloxated aluminium with the abovementioned adhesive product and plastic are employed, in particular, in the electronics industry, e.g. in mobile telephones or laptop computers.
