Patent number: 10857839Abstract: A tire 10 has a decoration portion 15 using a paint on a surface of a side portion 12. The decoration portion 15 has a white paint layer 16 formed on at least a part of the decoration portion 15, a color paint layer 17 disposed by laminating on the white paint layer 16 and having a thickness less than the thickness of the white paint layer 16, and a protective layer 18 disposed by laminating on the color paint layer 17 and having the thickness less than the thickness of the white paint layer 16. The elastic modulus of the protective layer is larger than the elastic modulus of the white paint layer and the color paint layer. A thickness of the decoration portion 15 as a whole, including the white paint layer 15, the color paint layer 17 and the protective layer 18, is 150 ?m or less.Type: GrantFiled: April 21, 2014Date of Patent: December 8, 2020Assignee: BRIDGESTONE CORPORATIONInventors: Keita Oshikane, Nobuyuki Hirai, Takashi Kuwahara, Kentaro Mizotani, Yuki Nakamura

Patent number: 10787041Abstract: Provided is a pneumatic tire including, on an outer surface of its sidewall portion, a decorative portion including a print layer and a protective layer located on a tire outer side of the print layer. The decorative portion further includes an intermediate layer located between the print layer and the protective layer. When a storage modulus of the print layer, a storage modulus of the protective layer, and a storage modulus of the intermediate layer are respectively defined as E1?, E2?, and E3?, the following relational expression is satisfied: E2?>E3?>E1?.Type: GrantFiled: July 24, 2015Date of Patent: September 29, 2020Assignee: BRIDGESTONE CORPORATIONInventors: Kentaro Mizotani, Nobuyuki Hirai, Takashi Kuwahara, Yuki Nakamura, Keita Oshikane, Toshio Furutaka, Yasuma Saito, Yukio Sugita

Patent number: 10603963Abstract: Provided is a pneumatic tire including, on an outer surface of its sidewall portion, a decorative portion including a print layer and inner and outer layers respectively disposed on tire inner and outer sides of the print layer. When storage moduli at 25° C. of the print, inner, and outer layers are respectively defined as E125?, E225?, and E325?, E125?<E225? and E125?<E325? are satisfied. When storage moduli at 80° C. of the print, inner, and outer layers are respectively defined as E180?, E280?, and E380?, and storage modulus variations ?1, ?2, and ?3 at high temperature of the print, inner, and outer layers are respectively defined as ?1=|E125??E180?|/E125?, ?2=|E225??E280?|/E225?, and ?3=|E325??E380?|/E325?, ?1<?2 and ?1<?3, and E225?>E280? and E325?>E380? are satisfied.Type: GrantFiled: July 24, 2015Date of Patent: March 31, 2020Assignee: BRIDGESTONE CORPORATIONInventors: Kentaro Mizotani, Nobuyuki Hirai, Takashi Kuwahara, Yuki Nakamura, Keita Oshikane, Toshio Furutaka, Yasuma Saito, Yukio Sugita
