Abstract:
1. A radiation curable flame retardant composition comprising at least one polymer precursor selected from the group consisting of monomers and oligomers comprising one or more (meth)acryl groups, at least one flame retardant (A) selected from cyclic phosphonate esters responding to formula (I) wherein n is 1, 2 or 3, m is 0, 1 or 2 and p is 0 or 1 with the proviso that n+m+p=3, R R R and at least one flame retardant (B) selected from organic phosphorus compounds different from the cyclic phosphonates of formula (I) wherein the polymer precursor comprises at least 5% by weight of one or more oligomers that are selected from the group consisting of urethane (meth)acrylates, polyester (meth)acrylates and epoxy (meth)acrylates.
