Abstract
Abstract An anti-solar polymer has in the macromolecular chain thereof at least one unit of the formula ##STR1## wherein F is a residue derived from an aromatic compound. The anti-solar polymer can also be one having in the macromolecular chain thereof at least one unit of the formula ##STR2## wherein F 1 is ##STR3## These polymers have the ability to absorb wave lengths of light in the range of about 280-315 millimicrons. The polymers are employed in a cosmetic composition.
