UV degradation

  1. May 13, 2009 #1
    Hi there, does anyone know which type of UV radiation would be most effective in polymer degradation or more importantly jet ink fading. Personally I think it should be UVC as it has the highest energy per photon but I could't find much about it so please help, it's very important as I'm behind with my work and can't afford guessing.

    Thanks in advance

    I can't find any thing scientific on the subject either. I would guess the photons with greater energy (E=hf) would degrade the colour faster. The colours are a mixture of different chemicals which might also have chemical bonds. High energy photons would break these bonds, so it would seem logical to assume that UVC would be the most damaging.
