An embossed sheet which is excellent in embossing properties, whitening resistance and transparency, can be prepared by using a resin composition containing specific ratios of (A) polypropylene having a specific melting point of 125.degree. C. or higher, (B) ethylene-.alpha.-olefin copolymer having specific properties and (C) random copolymer of aromatic vinyl compound and conjugated diene compound having specific properties. Further, the present invention provides the laminates which is made using the above embossed sheet and the method for producing them.

[ What is claimed is:] [1.] A laminate consisting essentially of of a base material and an embossed sheet prepared by embossing one or both surfaces thereof, said sheet made of a resin composition which comprises:(A) a polypropylene resin having a melting point of at least 125.degree. C., which melting point is determined by temperature rising analysis employing a differential scanning calorimeter having a temperature rising rate of 10.degree. C./min.; and(B) a resin component selected from the group consisting of an ethylene-.alpha.-olefin copolymer resin having a density of no more than 0.94 g/cm.sup.3 and a melting point of at least 70.degree. C. as determined by temperature rising analysis employing a differential scanning calorimeter, a random copolymer of an aromatic vinyl compound and a conjugated diene compound wherein the weight ratio of said aromatic vinyl compound to said conjugated diene compound is in the range of between 5:95 and 60:40 wherein at least 80% of said conjugated diene is saturated with hydrogen and mixtures thereof;wherein said component A is 45% to 80% by weight and said component B is 20% to 55% by weight, based on the total weight of said resin composition.
