Zusammenfassung:	The present invention relates to a method for preparing a binder composition for a formulation based on precious metals for decals; the method provides for making a polyamine and at least one dicarboxylic acid react to obtain a polyaminoamide; the polyamine has the formula H2NCH2RCH2NH2, wherein R is selected in the group consisting of: - Ph-, ~CH2CH2NHCH2CH2-; the molar ratio between the carboxylic acid and the polyamine is from 1.1:1 to 1:2. Cette invention concerne un procédé de préparation d'une composition de liant pour une formulation à base de métaux précieux pour décalcomanies. Le procédé consiste à faire réagir une polyamine et au moins un acide dicarboxylique pour obtenir un polyaminoamide ; la polyamine répondant à la formule H2NCH2RCH2NH2, où R est choisi dans le groupe constitué par : - Ph-, ~CH2CH2NHCH2CH2- ; le rapport molaire entre l'acide carboxylique et la polyamine étant de 1,1:1 à 1:2.
