Continued improvement in instrument performance is vital if colour measurement techniques are to keep abreast of customer demands explains the author.
Many industries, notably the automotive, printing, plastics and cosmetics industry, would not be what they are today if it were not for special effect pigments. At one time the first-generation classic effect pigments were all the rage, but now designers and stylists are crying out for the latest special-effect pigments. They are used to make an object distinctively appealing and fulfill this requirement admirably because of their gonioapparent nature. For example the change in their appearance with the change in angle of illumination or view. Looking at the past, stylists started with conventional metal pigments, like aluminium or bronze pigments, followed by pearlescent pigments, also know as mica pigments, pearl pigments or mineral effect pigments. In the last two years a new generation of effect pigments has become more and more popular. They are based on innovative substrates, like silica flakes or alumina flakes, ultra-thin multilayer interference film flakes or liquid crystals in organically crosslinked polymers. |
