Examples
Embodiment 1 to 8
[0162] In each of Examples 1 to 8, coatings were prepared according to the blends shown in Table 1. As the metal part of the surface light source, an aluminum alloy plate 5052-H32 of width 300 mm x length 100 mm x thickness 0.4 mm was used, and the aluminum alloy plate was subjected to bending processing by turning at 90°, thereby molding the curvature Corrugated with a radius of 1.0 mm. like figure 1 As shown in , on a metal member 12 of a molded product 10, convex portions 14 were formed horizontally at intervals of 60 mm, and concave portions 16 were formed between adjacent convex portions 14. The convex portion and the concave portion each had a radius of curvature of 1.0 mm. The moldings were treated with chromate-phosphate and coated to have a film thickness of 100 microns, wherein in Examples 1 to 3 the powder coatings shown in Table 1-1 were applied by electrostatic spraying, in Examples 4 to 8 The liquid coatings shown in Table 1-2 were applied by spraying.
