| 摘要 |
White pigmented, liquid, substantially solvent-free coating compositions are provided which may be rapidly cured to a solid, tightly adherent, opaque white coating upon exposure to radiation and particularly to electromagnetic radiation. More specifically, the compositions comprise epoxy monomers or prepolymers blended with a bis (epoxycycloalkyl)ester, a radiation-sensitive catalyst precursor effective to initiate polymerization of the epoxides upon exposure to radiation and certain alumina treated titanium dioxides, preferably of the rutile type.
