Polypropylene resin compositions and interior automotive trim parts

Disclosed is a flame-retardant resin laminate including a layer formed from a flame-retardant olefin resin composition and a layer formed from an olefin resin, wherein the flame-retardant olefin resin composition comprises 2.5 to 67% by weight of ammonium polyphosphate, 0.4 to 52.5% by weight of a nitrogen-containing organic compound, and 30 to 90% by weight of an olefin resin and has a weight ratio of the nitrogen-containing organic compound to the ammonium polyphosphate of 0.05 to 3. The flame-retardant resin laminate hardly generates black smoke or toxic gas, even when exposed to high temperatures or contacted with flames, and has excellent appearance, printability, weathering resistance and scratch resistance.

Metal-clad laminates and method for producing same

A flexible copper-applied substrate comprises a copper foil and a resin layer comprising a composite material of a polyimide and a polyimide silicone, the resin layer being directly formed on the surface of the copper foil, said substrate being producible by applying a polyamide acid composite composed of a mixed solution of a polyamide acid and a polyamide acid alkylsilane to a copper foil and heating.
