It was. Table 10 shows the evaluation results of the width of the temperature range in which the loss factor is 0.2 or more and the breaking strength.
  • Example 41 As layer B, viscosity average polymerization degree 600, average acetalization degree 70 mol%, vinyl acetate unit content 2 mol%, 95 parts by mass of polyvinyl butyral resin, viscosity average polymerization degree 1700, average acetalization degree 70 mol%, vinyl 5 parts by mass of polyvinyl butyral resin with an acetate unit content of 1 mol% and 10 parts by mass of Kuraray polyol P-510 (manufactured by Kuraray Co., Ltd., polyester polyol; consisting of 3-methyl-1,5-pentanediol and adipic acid Lamination using the same method as in Example 38, except that a polyester diol and a number average molecular weight per two hydroxyl groups of 500) were used to form a film having a thickness of 250 ⁇ m by extrusion. A body was prepared and physical properties were evaluated. Table 10 shows the evaluation results of the width of the temperature range in which the loss factor is 0.2 or
  • Example 42 A laminate was prepared using the same method as in Comparative Example 15 except that a coating solution containing elastomer Y was used instead of the coating solution containing elastomer X, and physical properties were evaluated. Table 10 shows the evaluation results of the width of the temperature range in which the loss factor is 0.2 or more and the breaking strength.
  • Example 43 A laminate was prepared using the same method as in Example 39 except that the thickness after drying of the B layer was 100 ⁇ m and the thickness after drying of the A1 layer was 300 ⁇ m, and physical properties were evaluated. . Table 10 shows the evaluation results of the width of the temperature range in which the loss factor is 0.2 or more and the breaking strength.
  • Example 44 A laminate was prepared using the same method as in Example 38 except that a coating solution containing elastomer Y was used instead of the coating solution containing elastomer X, and physical properties were evaluated.
