摘要： The present invention relates to a binder composition comprising



a) Component A comprising amino acid polymer(s) A1 and
b) Component B comprising component B1 selected from the group consisting of pentoses, hexoses, disaccharides of pentoses and/or hexoses and mixtures thereof,
wherein the amino acid polymer(s) A1 has(have) a total weight average molecular weight Mw, total of at least 800 g/mol and at most 10.000 g/mol and wherein the binder composition comprises at least 55 wt.-% amino acid polymer(s) A1 based on the total weight of the amino acid polymer(s) A1 and component B1.
