The coating method usable herein includes the step of applying onto a
substrate to be coated two or more powder coatings of which each color
is different, in which the
north face jacket charges are controlled in the above given ranges.
1. An article, comprising a coated substrate obtained by coating an
uncoated substrate with a single layer of a combination of two or more
powder coatings, comprising two or more color powder coatings wherein
the color of each power coating is different, wherein a difference in
northface jacket
charge of said two or more powder coatings is 5.0 μC/g or less; wherein
particles of each powder coating are not agglomerated; and wherein said
two or more powder coatings form a single layered coating film having a
homogeneous hue.
2. The article according to claim 1, wherein each of differences in true
specific gravities of said two or more powder coatings is 0.15 g/cc or
less.
3. The article according to claim 1, wherein ,
north face denali,each
of differences in apparent densities of said two or more powder
coatings is 0.020 g/cc or less.
4. The article according to claim 1, wherein each of differences in
softening points of said two or more powder coatings is 5.0° C. or less,
the softening points being measured using a capillary rheometer.
5. The article according to claim 1, wherein each of differences in
dielectric constants of said two or more powder coatings is 0.20 or
less.
6. The article according to claim 1, wherein each of ratios of the
electric resistance of said two or more powder coatings is from 0.1 to
10.
7. The article according to claim 1, wherein at least one powder coating
is a white powder coating containing a white pigment, and the remaining
powder coatings comprise no white pigments.
