Title:
PHOTORADIAL- AND PHOTOCATION-CURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2007/034914
Kind Code:
A1
Abstract:
The invention provides a curable composition which is cured by both photoradical-curing mechanism and photocation-curing mechanism and is improved in curability. The invention relates to a curable composition which is cured by both photoradical-curing mechanism and photocation-curing mechanism, which comprises (A) a vinyl polymer having in the molecule two or more groups represented by the general formula (1): -OC(O)C(Ra)=CH2 (1) (wherein Ra is hydrogen or an organic group having 1 to 20 carbon atoms) with the proviso that at least one of the groups is present at a molecular end and (B) an epoxy compound and/or an oxetane compound, characterized in that the concentration of N-containing compounds in the component (A) is 1000ppm or below and the concentration thereof based on the component (B) is 2300ppm or below.
