摘要:
A Photohardenable composition consisting essentially of a free radical polymerizable compound, an electron donating coinitiator, and a benzospiropyran, wherein the benzospiropyran undergoes ring opening to form a merocyanine upon exposure to a actinic radiation or heat and exposure to a second 296 radiation causes the composition to harden.
