ABSTRACT:
A polypropylene-laminated steel sheet is provided which is less liable to cause whitening on receiving impact shock and is superior in resistance to corrosion. A process for producing the polypropylene-laminated steel sheet is also provided. The polypropylene-laminated steel sheet comprises, at least on one side of the steel sheet, a layer (A) of modified polypropylene grafted with an unsaturated carboxylic acid, and, if desired, a layer (B) of polypropylene formed additionally on the layer (A), the modified polypropylene of the layer (A) and the polypropylene of the layer (B) having crystallinity of not more than 55%. The modified steel sheet is produced by the process which comprises melt-extruding and laminating a modified polypropylene (A) grafted with an unsaturated carboxylic acid on at least one side of a preheated steel sheet, and, if desired, a polypropylene (B) further thereon, and cooling the steel sheet, the modified polypropylene (A) and the polypropylene (B) together at a cooling rate of not less than 20.degree. C./sec at least in the temperature range of from 100.degree. C. to 55.degree. C.
