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.
