PROBLEM TO BE SOLVED: To obtain a resin composition for a decorative laminated sheet excellent in extension by rolls and to provide a method for producing a decorative laminated sheet free from pin holes using the same composition. SOLUTION: This resin composition contains 0.1-0.3 pt.wt. of a paraffin wax having <=55 deg.C melting point based on 100 pts.wt. of an unsaturated polyester resin composition obtained by reacting an acid component containing an α,β-unsaturated polybasic acid or acid anhydride as an essential component with a polyhydric alcohol to give an unsaturated polyester and dissolving the unsaturated polyester in a polymerizable monomer. The composition is made into a decorative laminated sheet to give the objective method for producing a decorative laminated sheet.
