The present invention relates water-soluble hindered amine compounds of the general formula (I):
wherein G
1
and G
2
are independently alkyl of 1 to 4 carbon atoms or are together pentamethylene; Z
1
and Z
2
are each methyl, or Z
1
and Z
2
together form an unsubstituted linking moiety or a linking moiety substituted by one or more groups selected from an ester, ether, hydroxy, oxo, cyanohydrin, amide, amino, carboxy or an urethane group; E is alkoxy of 1 to 18 carbon atoms, cycloalkoxy of 5 to 12 carbon atoms or aralkoxy of 7 to 15 carbon atoms, or E is —O-T-(OH)
b
; T is a straight or branched chain alkylene of 1 to 18 carbon atoms, cycloalkylene of 5 to 18 carbon atoms, cycloalkenylene of 5 to 18 carbon atoms, a straight or branched chain alkylene of 1 to 4 carbon atoms substituted by phenyl or by phenyl substituted by one or two alkyl groups of 1 to 4 carbon atoms; b is 1, 2 or 3 with the proviso that b cannot exceed the number of carbon atoms in T, and when b is 2 or 3, each hydroxyl group is attached to a different carbon atoms of T; and, HY is an inorganic or organic acid; and, wherein the total charge of cations is equal to the total charge of anions.
本发明涉及一般式(I)的水溶性受阻胺化合物:其中G1和G2分别是1至4个碳原子的烷基,或者一起是戊亚甲基;Z1和Z2分别是甲基,或者Z1和Z2一起形成一个未取代的连接基或一个由酯、醚、羟基、酮基、氰水合物、酰胺、氨基、羧基或脲基中选择的一个或多个基团取代的连接基;E是1至18个碳原子的烷氧基,5至12个碳原子的环烷氧基或7至15个碳原子的芳基氧基,或者E是—O-T-(OH)b;T是1至18个碳原子的直链或支链烷基,5至18个碳原子的环烷基,5至18个碳原子的环烯基,1至4个碳原子的直链或支链烷基,其被苯基取代,或者被一个或两个1至4个碳原子的烷基取代的苯基取代;b是1、2或3,但b不能超过T中的碳原子数,当b为2或3时,每个羟基连接到T的不同碳原子;HY是无机或有机酸;总阳离子电荷等于总阴离子电荷。
