(eng): Pigments that generate special effects like angle-dependent colour or decorative texture, have a growing economic significance and can be found in various industrial products and end-user applications. In decorative uses, special effect pigments provide three major advantages: (a) they can create an illusion of optical depth; for example it can be observed when applying pearlescent pigments in car paints; (b) they can generate subtle to startling angle-dependent eye-catching colour effects, which can be used in car paints or decorative printing; (c) they have the ability to imitate the effect of natural pearls in buttons, plastic bottles and many other decorative objects. This paper provides an insight into the recently discovered new applications of MultiFlect and Alegrace Spectacular polychromatic effect pigments. These effect pigments allow the creation of surfaces, which exhibit polychromatic light sparks under directed lighting, in various coating, printing or cosmetic applications. When used in interior architecture, eg in coil or powder coatings, different surface textures and interference colour effects can be perceived when exposed to different spectra of light, ie to create semismart surfaces.
