설포폴리에스터는 방향족 고리에 결합된 하나 이상의 설포네이트기를 함유하는, 작용기가 카르복실 또는 이의 에스터인 이작용성 설포단량체 30 몰% 이상 및 설폰화된 방향족 잔기가 아닌 이산 부분을 포함하는 이산 및 디올의 반응 산물을 포함한다. 본 발명의 설포폴리에스터 조성물은 1.0 meq/g 중합체 고체 초과의 전하 밀도를 갖는다. 본 발명의 다른 양태는 1 내지 50 중량%의 설포폴리에스터를 포함하는 코팅 조성물이다. A sulfopolyester includes the reaction product of a diacid and a diol wherein the diacid includes at least 30 mole percent of one difunctional sulfomonomer containing at least one sulfonate group bonded to an aromatic ring wherein the functional groups are carboxyl or esters thereof and a diacid moiety which is not a sulfonated aromatic moiety. The sulfopolyester composition of the present invention has a charge density of greater than 1.0 meq/g polymer solids. Another aspect of the invention is a coating composition containing from 1 to 50 weight percent of the sulfopolyester.
