Procedure for the obtaining of self-adhesive tapes or folios resistant to solvents, to temperature and to atmospheric influences. (Machine-translation by Google Translate, not legally binding)
Procedure for obtaining self-adhesive strips or sheets resistant to solvents, temperature and atmospheric influences in which a pressure-sensitive binder mass is applied on a flexible base, based on an acrylic acid ester copolymer, which contains a catalyst, and then subjected on the basis to a hardening by a thermal action of short duration, characterized in that an adhesive with a copolymerized is applied which is obtained by polymerization of (a) 100 parts by weight of an alkyl acrylate, whose alcohol component contains at least 4 carbon atoms, or of several alkyl acrylates with 1 to 14 carbon atoms in the alcohol component, of which, at least half, have 4 carbon atoms or more in the alcohol component , with (b) 0.25 to 11 parts by weight of one or more monomers polymerizable therewith, which in addition to the polymerizable double bonds contain in the molecule epoxide radicals capable of reaction, and optionally with (c) 0.25 up to 15 parts by weight of one or more monomers, which, in addition to polymerizable double bonds, contain in the molecule acid anhydride radicals, or with (d) 0.25 to 3 parts by weight of polymerizable compounds which, in addition to double bonds , contain in the molecule carboxylic radicals, or with (e) 0.25 to 15 parts by weight of diketone (β-oxivinylacetic acid lactone), the total amount of components (b) and (2) having to be in the copolymerized each time. c) either (b) and (d) or (b) and (e) do not exceed approximately 15 parts by weight, and to which before the application on the base approximately 0.05 to 5% (referred to copolymerized) of a catalyst.
