Claims15
A flame-retardant adhesive resin composition comprising;
- at least one resin;
- and
- at least one halogen-free flame retardant composition wherein the resin composition includes essentially no halogen containing flame-retardant compositions wherein the halogen-free flame retardant is melamine cyanurate having a particle size of from 1 to about 20 microns.
An adhesive resin coated conductive metal foil having a first surface and a second surface wherein the first surface includes a flame-retardant resin layer comprising at least one resin, and at least one halogen-free flame retardant composition wherein the resin includes essentially no halogen containing flame-retardant compositions and wherein the flame retardant resin layer has a thickness of from about 35 to about 100 microns.
