Isoindoline pigment yellow 139 (P.Y.139), which is high thermal resistance and reddish yellow color. It has been used in general and high grade industrial paints including original automobile and automotive refinishes, in plastics, especially for metal deco. Isoindoline sample was synthesized at various condition from 1,3-diiminoisoindoline precursor with addition of isoindoline derivatives, and then crystallized at various conditions in autoclave. The chemical and crystalline structure of sample were analyzed by means of FT-IR spectrometer and X-ray Diffraction. The color properties were analyzed by means of color-difference meter, UV-Vis spectrometer. The shape and size of particles and dispersion stability were analyzed by means of field emission scanning electron microscope. The dispersion characteristics were tested utilizing turbiscan. |
