    • 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).
    • 一种涂料组合物,其包含粘合剂,载体,颜料,选自碱金属阳离子,铵阳离子及其混合物的阳离子,以及选自式I化合物和式I化合物的至少一种二氨基醇, 二级方程式 本发明还提供一种降低具有粘合剂,载体和颜料的涂料组合物的挥发性有机化合物(VOC)含量的方法,其包括在涂料组合物中包含前述A)阳离子和B)至少一种 二氨基醇。 二氨基醇可以是式(I):其中R 1和R 2独立地是C 1 -C 10烷基,或者R 1和R 2与它们所连接的碳一起形成任选地被C 1 -C 6取代的C 3 -C 12环烷基环 烷基。 例如,式(I)的化合物可以是2-(2-氨基-2-甲基丙基氨基)-2-(羟甲基)丙烷-1,3-二醇。 或者,二氨基醇可以是式(II):或其盐,其中R 1和R 2在每次出现时独立地为C 1 -C 6烷基; 在每次出现时,R 3独立地为H或C 1 -C 6烷基。 例如,式(II)的化合物可以是2,2' - ((2-羟基三亚甲基)二亚氨基)双(2-甲基-1-丙醇)。
