ABSTRACT:
A thermostable substrate for flexible circuit boards having excellent flame-resistance, handling, and storage qualities may be produced by treating a substrate of a nonwoven fabric or paper with a flame-resistant, halogen-free polymeric composition. The polymeric composition comprises an aqueous mixture of a copolymerizate of acrylic acid esters and styrene, and an aminoplastic or phenoplastic precondensate to which a mixture of fine-particle red phosphorus and fine-particle ammonium polyphosphate is also added.
