Fluorinated and Bio-Based Polyamides with High Transparencies and Low Yellowness Index. [PDF]
Polymers (Basel), 2018 Bio-based polyamides with high transparency and low yellowness were synthesized using 4,4′-bis(trifluoroacetamido)-α-truxillic acid (ATA-F1) and 4,4′-bis(pentafluoropropionamido)-α-truxillic acid (ATA-F2) as a fluoroalkylated aromatic dicarboxylic acid, and various aromatic diamines. The introduction of fluorine side chains improved the transparency of

A yellowness index for use in dentistry [PDF]
Journal of Dentistry, 2019 To develop an equation that predicts the perceptual yellowness of teeth.A large set of new psychophysical yellowness data were generated from an experiment where 500 participants each ranked a set of 58 shade guide samples. Two existing equations (WIO and b*) and one new equation (YIO) were evaluated by comparing their values for the 58 shade guide ...

Comparison between the Color Properties of Whiteness Index and Yellowness Index on the CIELAB
Textile Coloration and Finishing, 2013 The color properties of a white or nearly colorless fabric are represented by whiteness index (WI) or yellowness index (YI). These two indexes relate to a white fabric’s color quality. The purpose of this study was to identify the properties of WI and YI on the CIELAB through the simulations of estimation data for a systemization of color quality ...
