Claims
- 1. A process for producing a pneumatic tire having an air permeation preventive layer obtained from the curing of a liquid composition containing (i) a multi component copolymer polyamide resin, (ii) a curable resin, and (III) a curing agent for curing the curable resin, said process comprising:spraying or coating a liquid composition containing (i) a multi component copolymer polyamide resin, (ii) a curable resin, and (iii) a curing agent for curing the curable resin on a surface of a carcass layer of a green tire comprising unvulcanized rubber or the surface of a rubber layer provided on the surface of the carcass layer which has been halogenated, and then vulcanizing the green tire, whereby an air permeation preventive layer is formed.
- 2. A process for producing a pneumatic tire having an air permeation preventive layer obtained from the curing of a liquid composition containing (i) a multi component copolymer polyamide resin, (ii) a curable resin, and (iii) a curing agent for curing the curable resin, said process comprising:spraying or coating a liquid composition containing (i) a multi component copolymer polyamide resin, (ii) a curable resin, and (iii) a curing agent for curing the curable resin on a surface of a carcass layer of a green tire comprising unvulcanized rubber or the surface of a rubber layer provided on the surface of the carcass layer to which an adhesive has been coated, and then vulcanizing the green tire, whereby an air permeation preventive layer is formed.
- 3. A process for producing a pneumatic tire having an air permeation preventive layer obtained from the curing of a liquid composition containing (i) a multi component copolymer polyamide resin, (ii) a curable resin, and (iii) a curing agent for curing the curablespraying or coating a liquid composition containing (i) a multi component copolymer polyamide resin, (ii) a curable resin, and (iii) a curing agent for curing the curable resin on a surface of a carcass layer of a vulcanized tire or the surface of a rubber layer provided on the surface of the carcass layer which has been halogenated, followed by curing, whereby an air permeation preventive layer is formed.
- 4. A process for producing a pneumatic tire having an air permeation preventive layer obtained from the curing of a liquid composition containing (i) a multi component copolymer polyamide resin, (ii) a curable resin, and (iii) a curing agent for curing the curable resin, said process comprising:spraying or coating a liquid composition containing (i) a multi component copolymer polyamide resin, (ii) a curable resin, and (iii) a curing agent for curing the curable resin on a surface of a carcass layer of a vulcanized tire or the surface of a rubber layer provided on the surface of the carcass layer to which an adhesive has been coated, followed by curing whereby an air permeation preventive layer is formed.
- 5. A process for producing a pneumatic tire according to claim 1, wherein the air permeation preventive layer has an air permeation coefficient of 25×10−12 cc·cm/cm2·sec·cmHg (at 30° C.) or less, and a Young's modulus of 1 to 500 Mpa.
- 6. A process for producing a pneumatic tire according to claim 2, wherein the air permeation preventive layer has an air permeation coefficient of 25×10−12 cc·cm/cm2·sec·cmHg (at 30° C.) or less, and a Youngls modulus of 1 to 500 Mpa.
- 7. A process for producing a pneumatic tire according to claim 3, wherein the air permeation preventive layer has an air permeation coefficient of 25×10−12 cc·cm/cm2·sec·cmHg (at 30° C.) or less, and a Young's modulus of 1 to 500 Mpa.
- 8. A process for producing a pneumatic tire according to claim 4, wherein the air permeation preventive layer has an air permeation coefficient of 25×10−12 cc·cm/cm2·sec·cmHg (at 30° C.) or less, and a Young's modulus of 1 to 500 Mpa.
- 9. A pneumatic tire obtained according to the process of claim 1.
- 10. A pneumatic tire obtained according to the process of claim 2.
- 11. A pneumatic tire obtained according to the process of claim 3.
- 12. A pneumatic tire obtained according to the process of claim 4.
