摘要： Pressure-sensitive adhesive tapes or sheets containing nitroglycerin whose release and retention are regulated. Process for the production of pressure-sensitive adhesive tapes or sheets containing nitroglycerin, in which a rubber base adhesives applied on a backing is coated with softeners containing nitroglycerin and then covered with an impermeable protection sheet. Process for the production of pressure-sensitive adhesive tapes or sheets containing nitroglycerin, in which a backing is coated with adhesives comprising a rubber base adhesive basis and tackifiers, while a separator is coated with a solution of softeners for rubber base adhesives in which nitroglycerin is dissolved, and then the softener coated surface of the separator is laid on the adhesive-coated surface of the backing and they are kept at the temperature at which nitroglycerin is stable so that the nitroglycerin and softeners transfer into the adhesives.
