TATIANA CONSTANDACHE, ANGELA CEREMPEI, RODICA MURESAN, IRINA CRINA ANCA SANDU, AUGUSTIN MURESAN,ION SANDU Possibilities to Improve the Colour Properties of the Yellow 17 Pigment by Treatment with Metallic Salts


Abstract:
The objective of this work was the modification of the pigment Yellow 17 structure through a treatment with ZnCl2 and Na2SiO3 in order to improve its properties. The modifications that appear in pigment structure were revealed by UV-visible diffuse reflectance and EDX analysis. The synthesized pigments were used to colour the polypropylene. The chromatic modifications appeared through pigment colouring with modified pigments were evaluated by measuring the colour intensity and colour difference. The light fastness and UV protection of the coloured polypropylene samples were also highlighted. Keywords: organic pigments, polypropylene, colour measurements, light fastness, UV-protection
