1. photopolymerizable composition comprises:

  • Be at least a polymerizable compound of 1.0-99.0% by weight;

    Be at least a photosensitizer of 0.05-5.0% by weight, said photosensitizer is selected from the photochromic compound that changes color through incoherent UV rayed;

    Be the coinitiator of 0.2-6.0% by weight, under the situation that the light-initiated form of the said photochromic compound through said incoherent UV phototransformation exists,, be used for the said polymerizable compound of photopolymerization through visible-light activated said coinitiator;

    Be the polymer adhesive of 0-97.5% by weight;

    Be the plastifier of 0-6.0% by weight;

    Be the non-polymer solvent of 0-3.0% by weight,Wherein, Said photochromic compound is selected from the group of being made up of benzothiazole quinoline spiro-pyrans, phenoxy group aphthacene quinone and their potpourri, and perhaps said photochromic compound is selected from the group of being made up of two aromatic heterocyclic ethene, fulgenimide and their potpourri.
