<p><P>PROBLEM TO BE SOLVED: To provide a propylene-based foamed sheet excellent in design and rigidity. <P>SOLUTION: This propylene-based resin foamed sheet is produced by coextrusion and composed of a foamed layer comprising the propylene-based resin, a non-foamed layer 1 comprising 100 pts.wt. propylene-based resin and 10-100 pts.wt. talc, and a non-foamed layer 2 comprising 100 pts.wt. propylene-based resin and 1-100 pts.wt. pigment and not containing talc, where at least one surface of the propylene-based resin foamed sheet is the non-foamed layer, and the weight ratio of the foamed layer, the non-foamed layer 1 and the non-foamed layer 2 is: the foamed layer:the non-foamed layer 1:the non-foamed layer 2=100:(50-100):(5-20). <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
