    摘要: A polyester resin laminated plate which has a smooth surface, has less anisotropy of mechanical properties, is inexpensive, has no restriction in size, thickness, etc., and has a good cutting workability is produced by a process including the steps of melt-extruding a composition including 100 parts by weight of a thermoplastic polyester resin compounded with from about 5 to about 40 parts by weight of a fibrous reinforcing material and from about 5 to about 50 parts by weight of a granular inorganic compound to form sheets, forcibly cooling the sheets to a temperature lower than the glass transition point of the polyester resin to provide plural sheets having a surface crystallinity of less than about 10%, laminating these plural sheets, and hot-pressing them at a pressure of from about 15 to about 150 kg/cm.sup.2 and at a temperature of from about 80.degree. to about 260.degree. C., with the rate of temperature increase of about 3.degree. C./minute or more to reach the temperature.
