RéflectanceIndex. décimale : 667.9 Revêtements et enduits Résumé : In this paper, some derivatives of perylene bisimides are successfully synthesized and characterized using FTIR, HNMR and XRD techniques. In addition, their UV–Vis–NIR reflectance spectra are investigated. Synthesized pigments were planned to have high structural similarities as all of them were N,N′-diphenyl-3,4,9,10-perylenedicarboximide derivatives. The substituents are selected from two categories including activating groups and deactivating ones. The correlation between substituent electronic properties and NIR features of the synthesized pigments is investigated, while the data of three previously synthesized derivatives are included. The results have revealed interesting approximate correlation between NIR properties and electronic features of the substituents. Electronically activating groups reduce the reflectance values (on white substrate) of the pigments in comparison with nonsubstituted molecule, while deactivating ones increase the reflectance amount. This result can be a starting point for detailed studying of structure–NIR properties correlation in perylene pigments. Crystallinity (%) of the pigments is estimated using XRD patterns, and the probable correlation of this parameter with NIR properties of the pigments is investigated, and no meaningful correlation is detected. All the pigments are NIR-transparent and subsequently are capable to be used as cool pigments.

Spectrométrie de masseIndex. décimale : 667.2 Colorants et pigments Résumé : The isoline concept - based on simple geometric consideration and the knowledge about the real 3D disorientation distribution of effect pigment platelets - figures out sets of illumination angles φo and detection angles φd' where the internal angle of incidence γ on platelets having a fixed angle of disorientation δ is constant. Therefore, the number and the reflectivity of the pigments illuminated and detected the reflectivity of the pigments illuminated and detected under these conditions should always be the same. The isolines are independent of the type of effect pigment. This behaviour was proven by checking the spectral deviation and the colour differences on isolines measured by GCMS-4 for interference and metallic effect pigment coatings. Within the measurement accuracy limits and the assumptions made for deriving the theoretical isolines, the isoline concept was confirmed.
Further, a geometric-probabilistic model to calculate the overlay structure of platelet effect pigments was developed. Here the focus was taken on the dependence of the optical texture on the PMC, the particle diameter, the thickness and the orientation.Note de contenu : - The geometry of effect pigments and its impact on apperance

Revêtements en bâtiment:Peinture en bâtimentIndex. décimale : 667.2 Colorants et pigments Résumé : Optimisation of the scattering efficiency of titanium dioxide can produce considerable cost savings. Ways to measure the efficiency of use of TiO, and to improve it are described. What is referred to as 'highly treated' TiO, can further improve opacity. This in turn can result in lower paint consumption, minimising environ-mental impacts.
One of the main functions of architectural paint is to hide a surface and improve its appearance. Hiding can be obtained either by scattering visible light or by absorbing it. For white paints, absorption is minimised, so that hiding in thin paint films can only be obtained by light scattering. Because of its high refractive index (RI), titanium dioxide (Ti02) is the most efficient pigment for scattering visible light and its lack of absorption in the visible light range makes it the best white pigment available.
Since light scattering is the key parameter controlling hiding in white pain) or whitening strength in tinted paints, more efficient use of Ti02 can lead to improved hiding.
This can reduce the number of paint layers needed for full coverage and hence speed up painting. Fewer paint layers saves costs and raw materials and hence reduces the environmental impact of the paint.
This paper describes how Ti02 efficiency can be assessed and how that knowledge can be used to prioritise hiding optimisation programmes.Note de contenu : - Factors influencing hiding power in paints
