HIKARISHOKUBAIKEI OYOBI GAIHIKARISHOKUBAIKEIOGANJUSURU SHIGAISENKOKASEIHIFUKUSOSEIBUTSU
Document Type and Number:
Japanese Patent JPS5169492
Kind Code:
A
Abstract:
The oxygen inhibition of the photopolymerization of acrylic resins is reduced by employing a photocatalyst system containing an aromatic ketone and/or aromatic aldehyde photosensitizer having a triplet energy in the range of from about 54 kilocalories per mole to about 72 kilocalories per mole and which promotes polymerization through bimolecular photochemical reactions of the energy donor type and an aromatic ketone photoinitiator which generates a radical pair by way of unimolecular homolysis resulting from photoexcitation. An exemplary photocatalyst system is benzophenone and isobutyl benzoin ether.
