Abstract:
A method of stabilizing a material which is subject to degradation by actinic radiation by incorporating into said material an amount of an actinic radiation stabilizer composition effective to stabilize the material against the effects of actinic radiation, wherein the actinic radiation stabilizer composition comprises a bondable triazine compound of formula (I), (II) or (III): whereineach X is independently selected from hydrogen and a blocking group; each of Y and Z is independently selected from an aryl ring of the formula (IV) each R is independently selected from a hydrogen, a hydrocarbyl group and a functional hydrocarbyl group; each R1, R2, R4, R4â€² and R4â€³ is independently selected from hydrogen, hydrocarbyl, functional hydrocarbyl, â€”O(hydrocarbyl), â€”O(functional hydrocarbyl), â€”SR, halogen, â€”SO2R, â€”SO3R, â€”COOR, â€”COR, â€”OCOR, â€”NRR and cyano; and each R3 is independently selected from â€”R, â€”OR, â€”SR, halogen, â€”SO2R, â€”SO3R, â€”COOR, â€”COR, â€”NRR and cyano; characterized in that at least one R group of a 4-position â€”OR group is selected from a group of the formulas (V), (VI) and (VII): whereinA is selected from â€”O(O)Câ€”; â€”C(O)â€”; â€”SOâ€”; â€”SO2â€”; and â€”OSO2â€”; each of A1 and A3 is independently selected from â€”COOR7; â€”COOâˆ’M+; â€”C(O)R7; â€”C(O)NR7R8; â€”CN; â€”NO2; â€”SOR7; â€”SO2R7; â€”SO2OR7 and â€”SO2NR7R8; A2 is selected from â€”C(O)â€”; â€”R9C(O)â€”; â€”R9OC(O)â€”; â€”SOâ€”; R9SOâ€”; â€”SO2; â€”R9SO2â€”; and â€”R9OSO2â€”; M+ is a cationic moiety; each of R5 and R9 is independently a hydrocarbylene group; R6 is selected from H and an alkyl of 1-4 carbon atoms; and each of R7, R8 and R10 is independently selected from H, a hydrocarbyl group and a functional hydrocarbyl group, wherein each blocking group is independently selected from at least one member of the group consisting of allyl, â€”CORa, â€”O2Rb, â€”SiRcRdRe, â€”PRfRg, â€”PORfRg, and â€”CONHRh; whereineach Ra is independently selected from C1-C8 alkyl, halogen-substituted C1-C8 alkyl, C5-C12 cycloalkyl, C2-C8 alkenyl, â€”CH2â€”COâ€”CH3, C1-C12 alkoxy, and phenyl or phenoxy which is unsubstituted or substituted by C1-C12 alkyl, C1-C4 alkoxy, halogen and/or benzyl; each Rb is independently selected from C1-C12 alkyl, C6-C10 aryl and C7-C18 alkylaryl; each Rc, Rd and Re is independently selected from C1-C18 alkyl, cyclohexyl, phenyl and C1-C18 alkoxy; each Rf and Rg is independently selected from C1-C12 alkoxy, C1-C12 alkyl, C5-C12 cycloalkyl, and phenyl or phenoxy which is unsubstituted or substituted by C1-C12 alkyl, C1-C4 alkoxy, halogen and/or benzyl; and each Rh is independently selected from C1-C8 alkyl, C5-C12 cycloalkyl, C2-C8 alkenyl, â€”CH2â€”COâ€”CH3, and phenyl which is unsubstituted or substituted by C1-C12 alkyl, C2-C8 alkenyl, C1-C4 alkoxy, halogen and/or benzyl; and the triazine compound is chemically bondable to a material to be stabilized through the group of formula (V), (VI) or (VII).
