POLYMERIZABLE COMPOSITION SUITABLE FOR LED LIGHT SOURCE

Title:

POLYMERIZABLE COMPOSITION SUITABLE FOR LED LIGHT SOURCE

Document Type and Number:

WIPO Patent Application WO/2010/008077

Kind Code:

A1

Abstract:

A polymerizable composition which exerts high curability even when an LED irradiation device as well as a halogen lamp type irradiation device is used and which rarely discolors even when stored for a long period. When used as dental material, the polymerizable composition attains high bond strength between a cured body of the composition and tooth substance. The polyerizable composition comprises both a photopolymerization initiator composition and a polymerizable monomer (D). The photopolymeization initiator composition comprises both a photopolymerization initiator component consisting only of a bisacylphosphine oxide (A) and an α-diketone (B), and a tertiary amine (C). The (A)/(B) weight ratio of the bisacylphosphine oxide (A) to the α-diketone (B) is 1:9 to 9:1 and the (D)/(C) weight ratio of the polymerizable monomer (D) to the tertiary amine (C) is 100:0.5 to 100:10.
