    Abstract: Self-extinguishing laminates are made by an improved process, wherein individual layers of a carrier material are impregnated with a thermosetting phenolic resin containing a flame-retardant agent and the impregnated layers are placed one above another and bonded together by compressing them at elevated temperature and under elevated pressure to give a hardened laminate. More specifically, finely pulverulent phosphorus pentanitride as a flame-retarding agent is dispersed in the plasticized or non-plasticized thermosetting phenolic resin, with or without a diluent; the phenolic resin, based on its solid matter content, and the phosphorus pentanitride being used in an approximate ratio by weight of 100:4 to 100:15; and the phenolic resin, based on its solid matter content, and the carrier being used in an approximate ratio by weight of 100:80 to 100:150.
