- 6. An anti-solar cosmetic composition comprising an aqueous, hydroalcoholic or oily solution containing an amount to assure protection against wave lengths of light in the erythematous zone of at least one anti-solar polymer containing in the macromolecular chain thereof at least one unit having the formula ##STR32## wherein F is ##STR33## wherein R.sub.1 and R.sub.2 represent alkyl having 1-4 carbon atoms and at least one unit derived from an ethylenically unsaturated monomer present in an amount of about 20-90 percent of the total weight of the polymer.
- 7. The anti-solar cosmetic composition of claim 6 wherein the said polymer is a copolymer of vinyl stearate/vinyloxycarbonylmethyl 4-methoxy cinnamate/vinyloxycarbonylmethyl cinnamate/vinyloxycarbonylmethyl 4-N,N-dimethylamino benzoate.
- 8. The anti-solar cosmetic composition of claim 6 wherein said ethylenically unsaturated monomer is selected from the group consisting of
- (a) N-vinylpyrrolidone,
- (b) methacryloyl D-glucosamine,
- (c) dimethylaminoethyl methacrylate,
- (d) stearyl methacrylate,
- (e) stearyl acrylate and
- (f) vinyl stearate.
- 9. An anti-solar cosmetic composition comprising an aqueous, hydroalcoholic or oily solution containing an amount to assure protection against wave lengths of light in the erythematous zone of at least one anti-solar polymer containing in the macromolecular chain thereof at least one unit having the formula ##STR34## wherein F is selected from ##STR35## wherein R.sub.1 and R.sub.2 represent alkyl having 1-4 carbon atoms, ##STR36## wherein R.sub.3 is selected from the group consisting of hydrogen and methoxy; ##STR37## wherein R.sub.4 is selected from the group consisting of --S--CF.sub.3 and --CF.sub.3 ; ##STR38## and at least one unit derived from an ethylenically unsaturated monomer present in an amount of about 20-90 percent of the total weight of the polymer.
- 10. An anti-solar cosmetic composition comprising an aqueous, hydroalcoholic or oily solution containing an amount to assure protection against wave lengths of light in the erythematous zone of at least one anti-solar polymer having the formula ##STR39## wherein F is selected from the group consisting of ##STR40## wherein R.sub.1 and R.sub.2 represent alkyl having 1-4 carbon atoms, ##STR41## wherein R.sub.3 represents hydrogen or methoxy, ##STR42## wherein R.sub.4 represents --S--CF.sub.3 or --CF.sub.3, ##STR43## wherein R.sub.4 has the meaning given above, ##STR44## R.sub.1 represents hydrogen or methyl and Y represents a radical selected from the group consisting of ##STR45## wherein X represents D-glucosamine, dimethylamino ethyl, quaternized or not and C.sub.18 H.sub.37, and ##STR46## wherein the unit ##STR47## comprises between about 20 and 85% of the total weight of said polymer.
- 11. An anti-solar cosmetic composition comprising an aqueous, hydroalcoholic or oily solution containing an amount to assure protection against wave lengths of light in the erythematous zone of at least one anti-solar polymer containing in the macromolecular chain thereof at least one unit having the formula ##STR48## wherein F.sub.1 represents a member selected from the group consisting of ##STR49## and at least one unit derived from an ethylenically unsaturated monomer, said unit being present in an amount between 20 and 80% of the total weight of said polymer.
