RéflectanceIndex. décimale : 668.5 Parfums et cosmétiques Résumé : In Effect pigments based on natural mica as well as on synthetically prepared substrates such as Synthetic mica, or Silica, Alumina or Borosilicates (Glass flakes), the surface area/particle size plays a crucial role in tailoring effect pigments with desired properties in cosmetic applications. With two pigment series, Sumicosâ„¢ HG ("high-gloss") Line and Prestige® Glow and Glam Line, we have recently build-up a technology to create new effect pigments that provide better chroma, color purity and sparkle in comparison to the conventional effect pigments. The article describes the science behind creating these effect pigments with improved reflectance.

The models investigated include the Berns and Petersen method, the modified Berns and Petersen method, the Reniff method, the Rich and Martin method and the R-model developed by Chung et al. In the paper, the Reniff method and the R-model were extended, and all the models were then evaluated using sample sets with different substrates. It was found that the extended Reniff method gave the best training performance and the worst testing performance. The Rich and Martin model, the three-term Chung model and the Berns and Petersen models, all with wavelength-dependent coefficients, gave better testing performance.

IsomérieEn chimie organique, on parle d'isomérie lorsque deux molécules possèdent la même formule brute mais ont des formules développées ou stéréochimiques différentes. Ces molécules, appelées isomères, peuvent avoir des propriétés physiques, chimiques et biologiques différentes.
On distingue différents types d'isomérie, notamment l'isomérie de constitution (isomérie plane) et l'isomérie de configuration (stéréoisomérie).

RéflectanceIndex. décimale : 667.9 Revêtements et enduits Résumé : In this study, five different perylene bisimide derivatives are synthesized, four of which are structural isomers. The pigments are used to prepare corresponding paints and their ultraviolet–visible–near infrared (NIR) reflectance is investigated on two optically different substrates, namely high absorptive and high reflective substrates. These pigments are classified according to their NIR properties. They show substantial differences in NIR reflectance, transmittance, and absorbance despite their structural similarities. This indicates that the NIR properties of perylene bisimide derivatives are dependent on the nature of N-substituent and electronic environment of the molecule. This study shows that the existence of bonds with high-frequency fundamental vibrations and their counts which were introduced as affecting parameters on the NIR properties of the perylene pigments is not the main affecting factor and we should seek it elsewhere such as the crystal structure and intermolecular interactions of the pigments.

RéflectanceIndex. décimale : 667.3 Teinture et impression des tissus Résumé : A multispectral imaging system, after necessary calibration, can measure the spectral reflectances of colour samples accurately at a high spatial resolution. A limitation is that agreement of its measurements with those of a reference spectrophotometer is affected by the reflective characteristics of sample materials. The state-of-the-art methods aim to improve interinstrument agreement using the spectral values of neighbouring bands. However, it is observed that non-neighbouring bands are more effective in modelling interinstrument agreement. Inspired by this observation, the present paper proposes a method for eliminating material dependency by least-squares regression among non-neighbouring spectral bands. The fundamental issue of band selection is solved using a binary differential evolution algorithm. Experimental results confirm that the proposed method is effective in reflectance correction in terms of both spectral and colorimetric accuracy. The method is of practical application to multispectral imaging systems when measuring the spectral reflectances of colour samples with different materials.
