ABSTRACT:
Paper distributing an active compound such as a pesticide or a lachrymatory agent, particularly intended to be used in buildings or closed enclosures.
This paper is intended to be burnt to ensure the dissemination of the active compound incorporated in the paper. To ensure an efficient and rapid dissemination by means of a large volume of combustion gas containing only a little smoke and originating from a special combustion reaction at a limited temperature so as not to decompose the active compound, this paper is a nitrocellulose-based paper in which the proportion of nitrogen is greater than 5% and in which the fibres consist of a mixture of cellulose and nitrocellulose fibres, this mixture comprising at least 18% of cellulose fibres and the active compound having a decomposition temperature above 130.degree. C.
