Abstract
The present invention provides: a curable composition which contains a bismuth compound, wherein a phosphoric acid ester having a (meth)acryloyl group is bonded to bismuth, and a nitrile compound having a radically polymerizable carbon-carbon double bond; a cured body which is obtained by curing this curable composition; a multilayer body which is composed of the above-described cured body and a cured body that is obtained by curing a photochromic curable composition; and a radiation protective material which is formed of the above-described cured body or the above-described multilayer body.
Claims5
A curable composition, comprising:
- a bismuth compound in which a phosphoric acid ester having a (meth)acryloyl group is bonded to bismuth;
- and a nitrile compound having a radically polymerizable carbon-carbon double bond, wherein the content of the phosphoric acid ester bonded bismuth compound relative to a total amount of the curable composition is 15 to 85 mass %;
- and wherein the content of the nitrile compound relative to 100 parts by mass of the phosphoric acid ester bonded bismuth compound is 5 to 100 parts by mass.
