Abstract
A laminated material is prepared in which a resin composition layer (A) containing a thermoplastic resin and an inorganic filler in a scaly or non-scaly form in an amount from 20% to 80% by weight of the total weight of the thermoplastic resin and the filler interposes a resin composition layer (B) containing a thermoplastic resin and an inorganic filler in an amount from 30% to 70% by weight of the weight of the inorganic filler contained in the resin composition layer (A), the filler being in a scally form when the filler in the layer (A) is in a scaly form or being in a non-scaly form when the filler in the layer (A) is in a non-scaly form with a thermoplastic resin layer. For the laminated material in which the scaly inorganic filler is contained in the layer (A), the layer (B) containing the thermoplastic resin and the non-scaly inorganic filler in the amount of 20% to 80% by weight of the total weight of the thermoplastic resin and the non-scaly filler is interposed between the layer (A) containing the thermoplastic resin and the scaly inorganic filler in the amount of 20% to 80% by weight of the total weight of the thermoplastic resin and the scaly inorganic filler and the thermoplastic resin (C).
