水性聚酯分散体、具有由所述水性分散体形成的涂层的制品和涂布方法
Abstract:
水性分散体，所述水性分散体包含：水；数均分子量大于7000道尔顿的疏水性芳族聚酯；和水分散性芳族聚酯分散剂；其中所述疏水性芳族聚酯和所述水分散性芳族聚酯分散剂形成稳定的水性分散体；并且其中基于所述疏水性芳族聚酯和所述水分散性芳族聚酯分散剂的总重量，所述疏水性芳族聚酯在所述水性分散体中的存在量小于50重量％。
Abstract(English):

An aqueous dispersion comprising: water; a hydrophobic aromatic polyester having a number average molecular weight of greater than 7,000 Daltons; and a water-dispersible aromatic polyester dispersant;wherein the hydrophobic aromatic polyester and the water- dispersible aromatic polyester dispersant form a stable aqueous dispersion; and wherein the hydrophobic aromatic polyester is present in theaqueous dispersion in an amount of less than 50 wt-%, based on the total weight of the hydrophobic aromatic polyester and the water- dispersible aromatic polyester dispersant.
