The invention relates to novel polyamines A1 of formula (I) or (II). Said polyamines are easy to produce from readily accessible raw materials and contain no or only a small concentration of primary amino groups and thus have hardly any blushing effect. The viscosity of the polyamines is low compared with polyamine/polyepoxy addition compounds of the polyamine on which polyamine A1 is based. The novel polyamines A1 can be used for formulating epoxy resin compositions that contain no benzyl alcohol and have no blushing effect. |
