PURPOSE:To obtain a thermoplastic resin sheet suitable for base material of stickers and labels and liquid crystal plates, etc., having excellent dimensional accuracy and almost free of thermal expansion and shrinkage by covering both sides of the thermoplastic resin sheet with a non-adhesive thermoplastic resin having less than a specific thermal expansibility. CONSTITUTION:A thermoplastic resin A (e.g., vinyl chloride resin composition) to which are added a stabilizer, a colorant, etc., as needed is co-extruded with one or more of non-adhesive thermoplastic resins B (e.g., low-density polyethylene, etc.) in such a way as to cover both sides of the resin A with the resin B to obtain an aimed sheet having a thermal expansibility of 0.3% or less. |
