Title:
DIMERIC CYANOACRYLATE COMPOUNDS AS RED-SHIFTED UV ABSORBERS
Document Type and Number:
WIPO Patent Application WO/2010/056452
Kind Code:
A3
Abstract:
Dimeric cyanoacrylate compounds of Formula (I) and Formula (II) having low volatility are provided for absorption of radiation in the UV-A region of the electromagnetic spectrum, which encompasses wavelengths between 320 nm and 400 nm. These compounds can also be blended with other UV absorbers and UV stabilizers and are useful as stabilizers of materials subject to degradation by UV radiation. An exemplary compound includes formula:
