duce different effects and also create distinct colors through
reflectance or refraction from the particles in the coating.
To create new colors and combinations with effect pigments, Ciba has also been modifying the crystal structure
of long established high-performance organic pigments,
like the red-to-violet quinacridone, which has been on the
market for around 30 years. “Much can be achieved by
changing the crystallization of pigments,” said Brown.
“As the economic crisis continues into
2010, we expect to see the consumer look
for calm and reassurance in the home,”
said Justine Fox, creative director at Global
Color Research, London.
Sun Chemical, part of Dainippon Ink & Chemicals of
Japan, introduced at the show an effect pigment with 10
shades of colors, including orange, violet, blue, green and red.
“The new product does not have any organic pigments,
the presence of which can cause weathering problems,” said
Martha Davies, Sun’s global product manager for effect pigments. “The colors are created through a mix of iron oxides
with mica coated with titanium dioxide. With different
degrees of oxidation, different colors can be created.”
Merck KGaA, Darmstadt, Germany, displayed at the
exhibition a series of different classes of effect pigments
based on different materials to provide a variety of colors
and textures with the objective of offering designers flexibility in their choice of colorants.
“This year we’re using the trade show to introduce our new
conceptual approach to the trade audience,” said Peter Geier,
Merck’s marketing manager for coatings pigments. “Its core
element is the fact that we are developing a series of effect pigments in which the variety of design and the performance in
the coating are taken into account at the same time.”
Merck has effect pigment brands based on natural mineral mica, calcium aluminium borosilicate, silicon dioxide,
aluminium oxide and bismuth oxychloride. They produce
different colors as a result of light refraction, interference
and reflection. Its Xirallic range, which uses an aluminium
oxide substrate coated with titanium dioxide can provide
gold, red, blue, green, violet and turquoise with a glittering
and shimmering appearance.

Its Pyrisma brand embraces a new generation of effect
pigments comprising eight different titanium dioxide
interference pigments of yellow, red, magenta, violet, indigo, blue, turquoise and green. The company claims they
“encompass the largest possible color space that can be
achieved with eight pigments.”
The pigments were presented at the show for the first
time in applications including plastic coatings on ski helmets, powder coated façade panels and in coil-coated aluminium designs.
Merck also displayed at the show an Audi automobile
with a Black Violet color tone which shows a strong glitter
in sunlight and then a color travel appearance in shady
lighting conditions.
Pigment producers are trying to satisfy the market’s
needs for a greater range of colors and effects but with the
use of fewer materials and at the lowest possible expense.
“In today’s economy, our customers are looking for more
effect pigments, color options and additional ways to cut
costs,” said Myron Petruch, president of Sun’s performance
pigments. CW
