Claim 5

The composition as defined in claim 1 wherein the ultraviolet absorbing agents include one or more UV-A absorbing and one or more UV-B absorbing agents.

Claim 6

The composition as defined in claim 4 wherein the UV-A absorbing agent or agents are present at from about 0.5% to about 10% by weight and the UV-B absorbing agent or agents are present at from about 3% to about 10% by weight.

Claim 7

The composition as defined in claim 5 wherein the UV-A absorbing agent is one or more selected from the group consisting of 2-(2'-hydroxy-5'-methylphenyl)benzotriazole; 2-(2'-hydroxy-5'-t-octylphenyl)benzotriazole; 2,4-dihydroxybenzophenone; 2-hydroxy-4-methoxybenzophenone; 2,2',4,4'-tetrahydroxybenzophenone; 2,2'-dihydroxy-4,4'-dimethoxybenzophenone; 2,2'-dihydroxy-4-methoxybenzophenone; 2-ethylhexyl-4-phenylbenzophenone carbonate; 2-hydroxy-4-methoxy-4'-methylbenzophenone; 2-hydroxy-4-(n-octyloxy)benzophenone; 4-phenylbenzophenone; and 2-ethylhexyl-2-cyano-3,3'-diphenylacrylate and the UV-B absorbing agent is one or more selected from the group consisting of 4-(dimethylamino)benzoic acid, ethyl ester; 4-(dimethylamino)benzoic acid, 2-ethylhexyl ester; 4-(dimethylamino)benzoic acid, pentyl ester; glyceryl p-aminobenzoate; isobutyl p-aminobenzoate; and isopropyl p-aminobenzoate.

Claim 8

The composition as defined in claim 5 wherein the UV-A absorbing agent is 2-hydroxy-4-methoxybenzophenone alone or in combination with 2,2'-dihydroxy-4-methoxybenzophenone and the UV-B absorbing agent is 4-(dimethylamino)benzoic acid, 2-ethylhexyl ester.

Claim 9
