摘要: In this paper, we describe the use of artificial opals from polymer beads as effect pigments in transparent industial and automotive coatings. For purpose, synthesized monodisperse colloids fluorinated methacrylates by surfactant-free emulsion polymerization. The monomers, combination with crosslinking, lead to a refractive index contrast, thermal stability, solvent resistivity necessary for pigments. After crystallization beads, crystal flakes iridescent colors can be obtained. act various transpartent industrial due photonic behavior or pigments, color flop up 100 nm are observed.
