Claims
- 1. An antistatic coat for coating a surface of a base body so as to prevent accumulation of electric charges in said base body, said antistatic coat havinga multi-layer structure comprising at least one antistatic layer and an outermost surface layer of said antistatic coat, and said antistatic layer comprises a water soluble or water dispersible polyester resin having a carboxyl group as a binder and sulfonated polyaniline with a particle size within a range of 0.01 to 1.0 μm as an organic conductive material.
- 2. An antistatic coat as claimed in claim 1, wherein said antistatic layer is disposed directly below said outermost surface layer of said antistatic coat.
- 3. An antistatic coat as claimed in claim 1, wherein said conductive material comprises a conductive polymer having π-electron conjugated system.
- 4. An antistatic coat as claimed in claim 3, wherein said conductive polymer having π-electron conjugated system is sulfonated polyaniline.
- 5. An antistatic coat as claimed in claim 4, wherein a particle size of said sulfonated polyaniline is within a range of 0.01 to 1.0 μm.
- 6. An antistatic coat as claimed in claim 3, wherein a thickness of said antistatic coat is within a range of 0.05 to 0.5 μm.
- 7. An antistatic coat as claimed in claim 1, wherein said conductive material comprises a conductive carbon black.
- 8. An antistatic coat as claimed in claim 7, wherein a primary particle size of said conductive carbon black is up to 40 nm, and a specific surface of said conductive carbon black is at least 130 m2/g.
- 9. An antistatic coat as claimed in claim 7, wherein an oil absorption of said conductive carbon black is at least 75 ml/100 g.
- 10. An antistatic coat as claimed in claim 7, wherein a primary particle size of said conductive carbon black is up to 40 nm, a specific surface of said conductive carbon black is at least 130 m2/g, and an oil absorption of said conductive carbon black is at least 75 ml 100 g.
- 11. An antistatic coat as claimed in claim 7, wherein a thickness of said antistatic coat is within a range of 0.05 to 0.2 μm.
- 12. An antistatic coat as claimed in claim 1, wherein said antistatic layer contains a polyester resin as a binder.
- 13. An antistatic coat as claimed in claim 1, wherein said antistatic layer is a primer layer having an antistatic property.
