Abstract:
A durability enchancing agent comprising the reaction product of a) ultraviolet light absorbers (UVAs) and mixtures thereof having a reactive functionality thereon; and b) a non-acrylic monomeric, oligomeric or polymeric component, having a reactive functionality thereon to react with the reactive functionality of a), wherein either a) or b) includes more than one carbamate functional group, group convertible to a carbamate group, or a group that crosslinks with a carbamate functional group, and the final product is a monomer-, oligomer or polymer bound UVA that includes more than one carbamate functional group, group convertible to a carbamate group, or a group that crosslinks with a carbamate functional group,wherein the UVA is selected from the group consisting of polymer-bound 2-hydroxyphenyl triazines having the formula ##STR19## in the formula (IIa) u is 1 to 2,r is an integer from 1 to 3,the substituents Y.sub.1 independently of one another are hydrogen, hydroxyl, halogen, halogenomethyl, alkyl having 1 to 12 carbon atoms, alkoxy having 1 to 18 carbon atoms,when u is 1, Y.sub.2 is alkyl having 1 to 18 carbon atoms, alkyl which has 1 to 12 carbon atoms and is substituted by --COOH --COOY.sub.8, --CONH.sub.2, CONHY.sub.9, --ONY.sub.9 Y.sub.10, --CN, --OCOY.sub.11, or mixtures thereof; alkyl which has 4 to 20 carbon atoms which is interrupted by one or more oxygen atoms and is unsubstituted or substituted by hydroxyl or alkoxy having 1 to 12 carbon atoms; alkenyl having 3 to 6 carbon atoms, glycidyl, phenylalkyl which has 1 to 5 carbon atoms in the alkyl moiety and is unsubstituted or substituted by hydroxyl, chlorine and or methyl; --COY.sub.12 or SO.sub.2 Y.sub.13,wherein Y.sub.8 is amino, alkyl amine or cycloalkylamine having from 1 to 6 carbon atoms in the alkyl portion, alkyl having 1 to 18 carbon atoms, alkenyl having 3 to 18 carbon atoms, alkyl which has 3 to 20 carbon atoms, and is interrupted by one or more oxygen atoms, or said alkyl substituted by substituted by hydroxyl; alkenyl having 3 to 18 carbon atoms, glycidyl or phenylalkyl having 1 to 5 carbon atoms in the alkyl moiety,Y.sub.9 and Y.sub.10 independently of one another are alkyl having 1 to 12 carbon atoms, alkoxyalkyl having 3 to 12 carbon atoms, dialkylaminoalkyl having 4 to 16 carbon atoms or cyclohexyl having 5 to 12 carbon atoms,Y.sub.11 is alkyl having 1 to 18 carbon atoms, alkenyl having 2 to 18 carbon atoms or phenyl,Y.sub.12 is alkyl having 1 to 18 carbon atoms, alkenyl having 2 to 18 carbon atoms, phenyl, alkoxy having 1 to 12 carbon atoms, phenoxy, alkylamino having 1 to 12 carbon atoms or phenylamino,Y.sub.13 is alkyl having 1 to 18 carbon atoms, phenyl or alkylphenyl having 1 to 8 carbon atoms in the alkyl radical; and when u is 2, Y.sub.2 is alkylene having 2 to 16 carbon atoms, alkylene having 4 to 12 carbon atoms and is interrupted by one or more --O-- atoms and/or is substituted by hydroxyl; --CH.sub.2 CH(OH)CH.sub.2 --O--Y.sub.15 --OCH.sub.2 CH(OH)CH.sub.2, or --(CH.sub.2).sub.m --CO.sub.2 --Y.sub.18 --OCO--(CH.sub.2).sub.m, in which m is 1,2 or 3,Y.sub.15 is alkylene having 2 to 10 carbon atoms, phenylene or a group -phenylene-M-phenylene- in which M is --O--, --S--, --SO.sub.2 --, --CH.sub.2 -- or --C(CH.sub.3).sub.2 --, andY.sub.18 is alkylene having from 2 to 10 carbon atoms or alkylene which has 4 to 20 carbon atoms and is interrupted once or several times by oxygen.
