[PROBLEMS] To provide a novel flame-retardant thermosetting material. The object of the present invention is to provide a thermosetting material in which a phosphinate represented by the following formula (I) and / or a diphosphinate of the following formula (II) and / or at least one of these polymers are used as a flame retardant. Embedded image Wherein R 1 and R 2 may be the same or different and are linear or branched C 1 -C 6 -alkyl and / or aryl; R 3 is linear or A branched C 1 -C 10 -alkylene group, C 6 -C 10 is an arylene group, -alkylarylene group or -arylalkylene group; M is Mg, Ca, Al, S b, Sn, Ge, Ti, Zn, Fe, Zr, Ce, B i, Sr, Mn, Li, Na and / or K; m is 1-4; n is 1-4; and x is 1 And at least one synergistic component selected from the group consisting of metal hydroxides, nitrogen compounds and phosphorus-nitrogen compounds. |
