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 ##STR00001## where for example E and E' are
2-hydroxycyclohexyloxy, 2-hydroxy-2-methylpropoxy, benzyloxy, methoxy,
propoxy, hexyloxy, heptyloxy, octyloxy or cyclohexyloxy, R.sub.x is for
example --NH.sub.2.sup.+CH.sub.2CH.sub.2OH Cl.sup.-,
--NH.sub.3.sup.+-OAc, .dbd.NOH, --NHCH(CH.sub.3)COO.sup.-K.sup.+,
--NHCH.sub.2CH.sub.2N(CH.sub.3).sub.2.sup.+-OAc,
--NHCH.sub.2CH.sub.2SO.sub.3.sup.-K.sup.+,
--NHCH(COO.sup.-K.sup.+)CH.sub.2CH.sub.2SCH.sub.3,
--NHCH.sub.2COO.sup.-K.sup.+, --OCH(CH.sub.3)COO.sup.-K.sup.+,
--OCH.sub.2CH.sub.2N(CH.sub.3).sub.2.sup.+-OAc,
--OCH.sub.2CH.sub.2SO.sub.3.sup.-K.sup.+,
--OCH(COO.sup.-K.sup.+)CH.sub.2CH.sub.2SCH.sub.3 or
--OCH.sub.2COO.sup.31K.sup.+, and where R.sub.5 comprises repeating units
of --(OCH.sub.2CH.sub.2)--, --(OCH.sub.2CH.sub.2(CH.sub.3))--,
--(CH.sub.2CHCOOH)--, --(CH.sub.2C(CH.sub.3)COOH)--,
--(CH.sub.2CHCOOCH.sub.3)--, --(NHCH.sub.2CH.sub.2)--,
--(CH.sub.2CHOH)--, --(CH.sub.2CHCONH.sub.2)-- or
--(CH.sub.2CH(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.
