  The present invention relates to a continuous process for producing polyester resins suitable as binders for compatible thermosetting paints, which comprises the following steps : a) polycondensation of an oligomer of one or more polyfunctional organic acids and one or more polyfunctional alcohols, both with functionalities ranging from 2 to 4, and/or one or more epoxides, with one or more polyfunctional organic acids and/or one or more polyfunctional alcohols, both with functionalities ranging from 2 to 4, and/or one or more epoxides, in the presence of an esterification catalyst and stabilizers, obtaining hydroxylated polyester resins with an OH number ranging from 15 to 300 mg KOH/g and with an acidity number ranging from 1 to 20 mg KOH/g and/or carboxylated polyester resins with an acidity number ranging from 15 to 100 mg KOH/g with an OH number ranging from 1 to 20 mg KOH/g; b) hot homogenizing at least two batches of polyester resin obtained at the end of step a), filtration and continuous discharge. The present invention also relates to paints based on said polyester resins and the process for obtaining them.
