[0344] As described above, if the conditions in the invention are met, advantageous effects can be exerted to be able to obtain a resin layered body having excellent low-temperature thermoformability and favorable appearance so as to suppress occurrence of interference fringes.

[0345] Specifically, as shown in Table 2, when Production Examples 1A to 4A, in which the methacrylic resin (C) and the specific styrene copolymer (D) were blended in the pelletized thermoplastic resin (B), and Comparative Production Examples 3A to 4A, which include only the methacrylic resin (C), were compared, the refractive index was higher in Production Examples 1A to 4A.

[0346] In addition, when the Production Examples 1A to 4A and Comparative Production Examples 6A to 9A, in which the methacrylic resin (C) and the styrene copolymer (E) other than the specific styrene copolymer (D) were blended, were compared, the Production Examples 1A to 4A had more transparent and better appearance.

[0347] As shown in Table 3, Production Examples 1B to 12B, in which the methacrylic resin (C) characteristic of a high refractive index and the specific styrene copolymer (D) were blended and pelletized to prepare the thermoplastic resin (B) and the thermoplastic resin (B) and the specific polycarbonate-based resin (A) were then layered in the resin layered body before hard coating application, and Comparative Production Examples 7B to 12B, in which just the methacrylic resin (C) was pelletized to prepare the thermoplastic resin and the thermoplastic resin and the specific polycarbonate-based resin (A) were then layered, were compared. Here, the resin layered bodies of the Production Examples 1B to 12B had more favorable interference fringes.

[0348] In addition, Production Examples 1B to 12B and Comparative Production Examples 13B to 15B, in which just the specific styrene copolymer (D) was pelletized to prepare the thermoplastic resin and the thermoplastic resin and the specific polycarbonate-based resin (A) were then layered, were compared. Here, the resin layered bodies of the Production Examples 1B to 12B had less cracking at a bent portion during hot press forming.

[0349] Further, Production Examples 1B to 12B and Comparative Production Examples 16B to 42B, in which the polycarbonate-based resin (G) other than the specific polycarbonate-based resin (A) was layered, were compared. Here, the resin layered bodies of the Production Examples 1B to 12B had less spring back during hot press forming.

[0350] As shown in Table 4, Examples 1 to 12, in which the methacrylic resin (C) and the specific styrene copolymer (D) were blended and pelletized to prepare the thermoplastic resin (B), the thermoplastic resin (B) and the specific polycarbonate-based resin (A) were then layered, and a surface of the thermoplastic resin (B) on one side had a hard coating in the resin layered body after hard coating application, and Comparative Examples 7 to 12, in which just the methacrylic resin (C) was pelletized to prepare the thermoplastic resin, the thermoplastic resin and the specific polycarbonate-based resin (A) were then layered, and a surface of the thermoplastic resin on one side had a hard coating, were compared. Here, the resin layered bodies of the Examples 1 to 12 had more favorable interference fringes, which was similar to those before the hard coating application.

[0351] In addition, Examples 1 to 12 and Comparative Examples 13 to 15, in which just the specific styrene copolymer (D) was pelletized to prepare the thermoplastic resin, the thermoplastic resin and the specific polycarbonate-based resin (A) were then layered, and a surface of the thermoplastic resin on one side had a hard coating, were compared. Here, the resin layered bodies of the Examples 1 to 12 had less cracking at a bent portion during hot press forming, which was similar to those before the hard coating application.

[0352] Further, Examples 1 to 12 and Comparative Examples 16 to 42, in which the polycarbonate-based resin (G) other than the specific polycarbonate-based resin (A) was layered and a surface of the thermoplastic resin on one side had a hard coating, were compared. Here, the resin layered bodies of the Examples 1 to 12 had less spring back during hot press forming, which was similar to those before the hard coating application.

[0353] Furthermore, Examples 1 to 12 and Comparative Examples 1 to 6, in which the methacrylic resin (C) and the specific styrene copolymer (D) were blended at a ratio other than the specific ratio and pelletized to prepare the thermoplastic resin, the thermoplastic resin and the specific polycarbonate-based resin (A) were then layered, and a surface of the thermoplastic resin on one side had a hard coating, were compared. Here, the resin layered bodies of the Examples 1 to 12 had less cracking at a bent portion during hot press forming, which was different from those before the hard coating application.
