Abstract:
1. A method of protecting a substrate from the effects of ultraviolet light comprising applying to the substrate an effective ultraviolet light protective amount of a composition comprising one or more water-soluble polyaminoamides, said water-soluble polyaminoamides selected from the group consisting of: dimethyl terephthalate-diethenetriamine-adipic acid condensation polymer capped with methyl salicylate; adipic acid-diethylenetriamine condensation polymer capped with methyl salicylate; dimethyl terephthalate-diethylenetriamine-DBE-2 dibasic ester condensation polymer capped with methyl cinnamate; dimethyl terephthalate-diethylenetriamine-DBE-2 dibasic ester condensation polymer capped with cinnamic acid; dimethyl terephthalate-diethylenetriamine-DBE-2 dibasic ester condensation polymer capped with 4-methoxycinnamic acid; dimethyl terephthalate-diethylenetriamine-DBE-2 dibasic ester condensation polymer capped with methyl salicylate; dimethyl terephthalate-diethylenetriamine-DBE-2 dibasic ester condensation polymer capped with methyl salicylate and cross-linked with poly(ethylene glycol) diglycidyl ether; dimethyl terephthalate-diethylenetriamine-DBE-2 dibasic ester condensation polymer capped with methyl salicylate and modified with sodium chloroacetate; dimethyl terephthalate-diethylenetriamine-DBE-2 dibasic ester condensation polymer capped with methyl salicylate and modified with N-(3-chloro-2-hydroxypropyl) trimethylammonium chloride; dimethyl terephthalate-diethylenetriamine-DBE-2 dibasic ester condensation polymer capped with methyl salicylate and modified with poly(ethylene glycol) diglycidyl ether and dodecyl/tetradecyl glycidyl ether; and dimethyl terephthalate-diethylenetriamine-DBE-2 dibasic ester condensation polymer capped with methyl salicylate and modified with poly(ethylene glycol) diglycidyl ether, dodecyl/tetradecyl glycidyl ether and N-(3-chloro-2-hydroxypropyl) trimethylammonium chloride.
