Document Type and Number:
Japanese Patent JP2019019309
Kind Code:
A
Abstract:
To overcome a problem that when a monomer having large molecular weight is selected as a polymerizable monomer, it hardly generates odor specific to the polymerizable monomer, but curing property is inferior when an active energy ray is radiated, and when for example an ultraviolet light-emitting diode radiating ultraviolet ray having a peak at wavelength of 395 nm is used as a means for radiating the active energy ray, curing property at irradiation and strength after curing are inferior.SOLUTION: The composition contains a polymerizable acrylamide compound (A1) having an ester structure and an acyl phosphine oxide-based polymerization initiator (B1), and molecular weight of the acrylamide compound (A1) is 150 to 200.SELECTED DRAWING: None
