Claim Text:
1. A polyester AB consisting of moieties derived from di-or polyfunctional organic acid compounds A and moieties derived from di- or polyfunctional organic hydroxy compounds B, wherein A consists of an amount of substance-fraction a 1 of from 0.2 to 0.8 of at least two acid compounds A1, and an amount of substance-fraction a 2 of from 0.2 to 0.8 of at least two acid compounds A2, and wherein the compounds B consist of an amount of substance-fraction b 1 of from 0.05 to 0.8 of at least one hydroxy functional compound B1, and an amount of substance-fraction b 2 of from 0.2 to 0.95 of at least one hydroxy functional compound B2, wherein the sum of the amount of substance fractions a 1 and a 2 is 1, and the sum of the amount of substance fractions b 1 and b 2 is 1, and wherein: A1 are independently selected from the group consisting of isophthalic acid, trimellithic acid anhydride, hexahydrophthalic acid, cyclohexane-1,4-dicarboxylic acid, and tetrahydrophthalic acid, and A2 are independently selected from the group consisting of adipic acid, dimer fatty acids, and sebacic acid, and B1 are independently selected from the group consisting of trimethylolpropane, 1,2-bishydroxymethyl cyclohexane, and 1,2-dihydroxy-propane, and B2 are selected from the group consisting of 1,4-butanediol, 1,6-hexanediol, 2,2′-dihydroxydiethyl ether, and 1,2-bis(2-hydroxypropoxy)propane.
