1. a multi-layer optical film, including:

  • First group of internal layer, described first group of internal layer is arranged to be done by constructive interference or cancellationRelate to and optionally reflect light, thus the first reflection characteristic is provided, described first group of layer include forBirefringent at least some ground floor, and described first group of layer also have the first absorption characteristic,Be exposed to have carve paint the light of wavelength time, described first absorption characteristic heats with being suitable to absorbabilityDescribed first group of layer, adds heat and be enough to be reduced or eliminated the birefringence of described at least some ground floor,And described first reflection characteristic is changed into the 3rd reflection characteristic, keeps described first group simultaneouslyThe structural intergrity of layer;

    Second group of internal layer, described second group of internal layer is arranged to be done by constructive interference or cancellationRelating to and optionally reflect light, thus provide the second reflection characteristic, described second group of layer also includesFor the birefringent at least some second layer, and described second group of layer also has the second absorption characteristic,Be exposed to there is light that described quarter paints wavelength time, described second absorption characteristic is suitable to absorbability groundHeat described second group of layer, add heat and be enough to the described at least some second layer double are reduced or eliminatedRefraction, and described second reflection characteristic is changed into the 4th reflection characteristic, keep described simultaneouslyThe structural intergrity of second group of layer, the second absorption characteristic of described second group of internal layer is different from describedFirst absorption characteristic of first group of internal layer;

    WithFirst barrier layer, described first barrier layer is arranged on described first group of internal layer and described secondBetween group internal layer, described first barrier layer is suitable to stop the light that described quarter paints wavelength at least in part.
