Title:

CURABLE COMPOSITION AND PROCESS FOR PRODUCING CURED FLUOROCHEMICAL

Document Type and Number:

WIPO Patent Application WO/2005/085303

Kind Code:

A1

Abstract:

A curable composition giving a cured fluorochemical which is excellent in transparency, resistance to lights (especially a short-wavelength light having a wavelength of 200 to 500 nm), and heat resistance and which has a regulated volume, in particular a regulated thickness. The curable composition is characterized by comprising: a perfluorinated cyclic polyene which has an aliphatic ring structure made up of carbon atoms optionally including an oxygen atom and which has two or more carbon-carbon double bonds including at least one polymerizable carbon-carbon double bond in which at least one of the two carbon atoms forming the polymerizable carbon-carbon double bond is a carbon atom which is a member of the aliphatic ring structure; and a polymerization initiator. Also provided are: a cured fluorochemical obtained by curing the curable composition; an optical material comprising the cured fluorochemical; and a luminescent element encapsulated with the cured fluorochemical in a light-transmitting manner.
