pigments | Special effects
The effect is created through the combination of Merck’s metallic and pearlescent effect pigments with an overmoulding processing technique. Applications include packaging components, such as caps and closures, housings, automotive interior parts and
consumer electronics. The companies say the IM3D decoration technology can be

the incorporation into the desired target polymer at a dosage of 2-3%, thereby achieving a three-dimensional colour effect. We had to perform extensive tests in order to define the machine parameters and screw configura- tions of the extruder as well as to develop the master- batch formulations accordingly,” says Ludwig. Grafe adds that applications in polyolefins are easier
to implement than in technical materials, because the latter require higher processing temperatures and higher frictional forces. However, some formulations for technical polymers, such as polycarbonate, are being tested. PolyOne has introduced its new Impress colour
concentrates, which are designed to enhance polymer packaging with a high gloss metallic effect. The company says that this new technology enables packag- ing manufacturers to create unlimited combinations of colour and gloss for packaging with a brilliant, atten- tion-grabbing appearance. “With new Impress colour concentrates, packaging
manufacturers now have an outstanding option for winning consumer attention at the point-of-sale and can vary the amount of colourant and package wall thickness to create endless possibilities. In addition, these concentrates are easy to process in the polymers most commonly selected for packaging,” says Chris- toph Palm, Vice President, General Manager, Color and Additives EMEA & India for PolyOne. The company adds that Impress metallic effect

colourants can add value to packaging made with semi-crystalline polymers such as PET. These new formulations can be processed on standard injection stretch blow moulding machines, and create none of the flow lines that would disrupt the brilliant glossy surface. PolyOne has also collaborated with Merck of Germany to launch IM3D, a new technology enabling manufacturers to realise 3D imagery on packaging and consumer electronics. The companies say that with IM3D technology, manufacturers can create surfaces that appear to have depth and structure, although they are perfectly flat. Several processing steps were previously necessary to generate this effect in a polymer surface. Now, the 3D impression is created in just a single step during the injection moulding process.

incorporated into standard injection moulding machine production. Merck has also launched Thermaval, a new series of
effect pigments for high temperature applications. It says these pearlescent pigments remain stable up to 1,100°C and are therefore suitable for incorporation into high performance plastics that must withstand high usage temperatures. The four pigments from the Thermaval series with a metallic appearance are Thermaval Metallic Silver, Thermaval Metallic Gold, Thermaval Metallic Copper, and Thermaval Metallic Red. BASF recently added Lumina Royal Dragon Gold to
its highly chromatic Lumina Royal effect pigments range. The company says that it provides attractive shades, especially in combination with yellow pigments or in black reduction. Formulations of greenish gold hues with good sparkling and brilliance are said to be possible. BASF adds that initial market reception has been good and indicates that the pigment is expanding effect opportunities in the golden colour area.
