Zusammenfassung:PROBLEM TO BE SOLVED: To provide a sheet consisting of a thermoplastic resin composition having high impact strength, surface impact strength even with thin thickness, and low reduction of physical property when a pigment is added.SOLUTION: A sheet consists of a thermoplastic resin composition containing over 75 to 95 pts.wt. of a polycarbonate resin (I), 2 to 10 pts.wt. of a graft copolymer (II) obtained by graft copolymerization of a monomer mixture at least containing an aromatic vinyl monomer (b) and vinyl cyanide monomer (c) of 35 to 60 wt.% in a presence of a diene rubber polymer (a) of 40 to 65 wt.%, and 3 to 15 pts.wt. of a copolymer consisting of the aromatic vinyl monomer and vinyl cyanide monomer (III), and the total sum of (I) to (II) is 100 pts.wt. and the total sum of (II) and (III) is less than 25 pts.wt.
