ABSTRACT:
The present invention relates to novel chromophore-containing compounds useful as sunscreen agents which have the ability to absorb both UVA and UVB wavelength radiation. These compounds comprise a specific type of UVA-absorbing chromophore covalently bonded to a specific type of UVB-absorbing chromophore. The chromophore moieties are covalently bonded together such that the electron systems of these moieties are directly coupled to thereby form a new chromophore.
The present invention further relates to sunscreen compositions containing the hereinbefore described type of sunscreen agents. Furthermore, the present invention relates to methods for protecting the skin of humans or lower animals from the effects of UVA and UVB wavelength radiation. This method comprises topically applying to the skin an effective coating of a sunscreen composition of the present invention.
