- 10. A coated article as claimed in claim 1, wherein said coated article is obtained by applying a pigment-containing fluororesin coating composition on a substrate pattern-wise or uniformly thereby to form a patterned or uniform coating of said pigment-containing composition, and then applying a pigment-free fluororesin coating composition on the resulting surface uniformly thereby to form a uniform coating of said pigment-free composition,said pigment-free fluororesin coating composition comprising a dispersing medium and fluororesin particles dispersed therein, said dispersing medium mainly comprising a surfactant, said pigment-containing fluororesin coating composition comprising a dispersing medium, fluororesin particles, and pigment particles, said fluororesin particles and said pigment particles being dispersed in said dispersing medium, said dispersing medium mainly comprising a surfactant.
- 11. A coated article as claimed in claim 1, wherein the adhesion strength between said coating and said substrate is 1.5 Kg/cm or more, and said coating has an adhesion evaluation point of 8 or more as measured by a crosscut tape test in accordance with JIS K5400-1990, 8.5.2 after 10 times repetition of the tape application-stripping procedure.
- 12. A coated article as claimed in claim 1, wherein said coated article is obtained by applying a pigment-free fluororesin coating composition on said substrate uniformly thereby to form a uniform coating of said pigment-free composition, and then applying a pigment-containing fluororesin coating composition on the resulting surface pattern-wise or uniformly thereby to form a patterned or uniform coating of said pigment-containing composition,said pigment-free fluororesin composition comprising a dispersing medium and fluororesin particles dispersed therein, said dispersing medium mainly comprising a surfactant.
- 13. A coated article as claimed in claim 1, wherein said coated article is obtained by applying a pigment-containing fluororesin composition on said substrate pattern-wise or uniformly thereby to form a patterned or uniform coating of said pigment-containing composition, and then covering the resulting surface with a pigment-free fluororesin layer which is formed by applying a pigment-free fluororesin coating composition,said pigment-free fluororesin composition comprising a dispersing medium and fluororesin particles dispersed therein, said dispersing medium mainly comprising a surfactant.
- 14. A coated article as claimed in claim 1, wherein said coated article is obtained by applying a pigment-free fluororesin coating composition on said substrate uniformly thereby to form a uniform coating of said pigment-free composition, and then applying a pigment-containing fluororesin coating composition on the resulting surface pattern-wise or uniformly thereby to form a patterned or uniform coating of said pigment-containing composition,said pigment-containing fluororesin coating composition comprising a dispersing medium, fluororesin particles, and pigment particles, said fluororesin particles and said pigment particles being dispersed in said dispersing medium, said dispersing medium mainly comprising a surfactant.
- 15. A coated article as claimed in claim 1, wherein said coated article is obtained by applying said fluororesin coating composition on a fluororesin layer of a base fluororesin-coated article, as said substrate, uniformly or pattern-wise thereby to form a uniform or patterned coating of said composition, and then covering the resulting surface with a second fluororesin coating composition containing substantially no pigment and adhesive.
- 16. A coated article as claimed in claim 1, wherein said coated article is obtained by applying said fluororesin coating composition on a base having a finely roughened surface uniformly or pattern-wise thereby to form a uniform or patterned coating of said composition, and then covering the resulting surface with a second fluororesin coating composition containing substantially no pigment and adhesive.
