    • Sterically hindered alkoxyamine and hydroxy substituted alkoxyamine stabilizer compounds are made water compatible via certain backbones with affinity towards water. The sterically hindered amines are for example of the formula where for example E and E′ are 2-hydroxycyclohexyloxy, 2-hydroxy-2-methylpropoxy, benzyloxy, methoxy, propoxy, hexyloxy, heptyloxy, octyloxy or cyclohexyloxy, Rx is for example —NH2+CH2CH2OH Cl−, —NH3+−OAc, ═NOH, —NHCH(CH3)COO−K+, —NHCH2CH2N(CH3)2+−OAc, —NHCH2CH2SO3−K+, —NHCH(COO−K+)CH2CH2SCH3, —NHCH2COO−K+, —OCH(CH3)COO−K+, —OCH2CH2N(CH3)2+−OAc, —OCH2CH2SO3−K+, —OCH(COO−K+)CH2CH2SCH3 or —OCH2COO31K+, and where R5 comprises repeating units of —(OCH2CH2)—, —(OCH2CH2(CH3))—, —(CH2CHCOOH)—, —(CH2C(CH3)COOH)—, —(CH2CHCOOCH3)—, —(NHCH2CH2)—, —(CH2CHOH)—, —(CH2CHCONH2)— or —(CH2CH(NHCOH))—. These compounds are particularly effective in stabilizing aqueous polymer systems against the deleterious effects of oxidative, thermal and actinic radiation. The compounds are effective for example in stabilizing water borne coatings, aqueous inks, aqueous ink jet media and photocured aqueous systems.
    • 经受某些骨架使空间受阻的烷氧基胺和羟基取代的烷氧基胺稳定剂化合物与水相容,具有对水的亲和性。 空间位阻胺例如具有下式,其中例如E和E'是2-羟基环己氧基,2-羟基-2-甲基丙氧基,苄氧基,甲氧基,丙氧基,己氧基,庚氧基,辛氧基或环己氧基,Rx是例如-NH 2 + CH 2 CH 2 OH Cl - , - NH 3 + -OAc,-NOH,-NHCH(CH 3)COO-K +,-NHCH 2 CH 2 N(CH 3)2 + -OAc,-NHCH 2 CH 2 SO 3 -K +,-NHCH(COO-K +)CH 2 CH 2 SCH 3,-NHCH 2 COO-K + ,-OCH(CH 3)COO-K +,-OCH 2 CH 2 N(CH 3)2 + -OAc,-OCH 2 CH 2 SO 3 -K +,-OCH(COO-K +)CH 2 CH 2 SCH 3或-OCH 2 COO 31 K +,其中R 5包含 - (OCH 2 CH 2) - (OCH 2 CH 2(CH 3)) - , - (CH 2 CHCOOH) - , - (CH 2 C(CH 3)COOH) - , - (CH 2 CHCOOCH 3) - , - (NHCH 2 CH 2) - , - (CH 2 CHOH) - , - (CH 2 CHCONH 2) (CH 2 CH(NHCOH)) - 。 这些化合物在稳定水性聚合物体系中抵抗氧化,热和光化辐射的有害影响是特别有效的。 该化合物例如在稳定水性涂料,水性油墨,水性喷墨介质和光固化水性体系中是有效的。
