A coating composition comprising a binder, a carrier, a pigment, cations selected from the group consisting of alkali metal cations, ammonium cations, and mixtures thereof, and at least one diamino alcohol selected from the group consisting of compounds of Formula I and compounds of Formula II. The present invention also provides a method for reducing the volatile organic compound (VOC) content of a coating composition having a binder, a carrier, and a pigment, which comprises including in the coating composition the aforesaid A) cations and B) at least one diamino alcohol.
The diamino alcohol may be of Formula I:
wherein R
1
and R
2
are independently C
1
-C
10
alkyl, or R
1
and R
2
, together with the carbon to which they are attached, form a C
3
-C
12
cycloalkyl ring optionally substituted with C
1
-C
6
alkyl. For example, the compound of Formula I may be 2-(2-amino-2-methylpropylamino)-2-(hydroxymethyl)propane-1,3-diol.
Alternatively, the diamino alcohol may be of Formula II:
or salt thereof, wherein R
1
and R
2
are independently at each occurrence C
1
-C
6
alkyl; and R
3
is independently at each occurrence H or C
1
-C
6
alkyl. For example, the compound of Formula II may be 2,2′-((2-hydroxytrimethylene)diimino)bis(2-methyl-1-propanol).
