FLAME-RETARDED EPOXY RESIN COMPOSITION, PREPREGS CONTAINING THE SAME, LAMINATED SHEETS AND PRINTED WIRING BOARDS

Document Type and Number:

WIPO Patent Application WO/2004/092265

Kind Code:

A1

Abstract:

A flame-retarded epoxy resin composition which comprises an epoxy resin and a curing agent as the essential components and further contains a phosphorus-containing flame-retardant polyester resin obtained by the condensation or polycondensation of the reactive phosphorus compound represented by structural formula (&Igr ). Since the epoxy resin composition is enhanced in flame retardance by using the phosphorus-containing flame-retardant polyester resin serving as a halogen-free flame retardant, the composition little evolves toxic gas in burning and exhibits excellent moldability. Further, the products obtained by curing the composition are excellent in heat resistance, water resistance, chemical resistance, flame retardance, soldering resistance, moisture resistance, and tracking resistance and so on.
