The invention relates to hotmelt adhesives based on polyesters, having low VOC and fogging values. In particular, the invention is directed to a polyester based on polycarboxylic acids and di- or polyols, wherein the polyester including dicarboxylic acids of the formula HOOC—(CH2)x-COOH with x>10 and diols of the formula HO—(CH2)y-OH, with the proviso that at least 50 mole percent of the dicarboxylic acids, based on the total amount of polycarboxylic acid components, and at least 50 mole percent of the diols, based on the total amount of di- or polyols, satisfy the condition x+y>18, in hotmelt adhesives.
A hotmelt adhesive comprising polyesters based on polycarboxylic acids and di- or polyols, comprising dicarboxylic acids of the formula HOOC—(CH2)x-COOH with x>10 and diols of the formula HO—(CH2)y-OH, with the proviso that at least 50 mole percent of the dicarboxylic acids, based on the total amount of polycarboxylic acid components, and at least 50 mole percent of the diols, based on the total amount of di- or polyols, satisfy the condition x+y≥18.
