摘要： The invention relates to a flame-retardant and substantially solvent-free pressure-sensitive adhesive, to a process for preparing it and to its use for pressure-sensitive adhesive tapes. The pressure-sensitive adhesive of the invention comprises (a) at least one acrylate adhesive component, (b) at least one ammonium polyphosphate component and (c) at least one resin component. Coating one or both sides of a flame-retardant-impregnated carrier tape with a pressure-sensitive adhesive produces a flame-retardant pressure-sensitive adhesive tape.
