New organic yellow pigments with high fastness to light and weathering Part 2 Available to Purchase

For a better picture still of the fastness to weathering of the various pigments in the chosen paint system, it is worthwhile studying more closely the reflectance curves which were measured before and after weathering for the determination of the AN values. In Figure 10 the reflectance curves of the non‐weathered and the weathered areas of the test panels are shown in pairs, again in order of decreasing fastness, i.e. beginning with the pigment with the smallest AN value. However, only the reflectance curves of the 1:50 reductions are shown.
