Abstract
Changes in color of coated (painted) aluminum surfaces exposed to broa d-band synchrotron radiation (10-2000 eV) are investigated as a functi on of radiation dose (N). Quantitative color differences (Delta E(ab)( )) before and after exposure are obtained from spectral diffuse refle ctance measurements using the standard CIELAB formula. The results ind icate that the dose-response curve of the color-coated surfaces at lar ge photon doses can be described as Delta E(ab)() approximate to e(-d /N) constant.
