Abstract

L'invention concerne des compositions comprenant un mélange de: (1) un polymère vinylamidique, hydrosoluble, ionique, contenant suffisamment de vinylamide et de substituants -CHOHCHO pour être thermodurcissable ainsi que des substituants du type glyoxal et des substituants réagissant aux substituants du type glyoxal selon un rapport dépassant environ 0,02:1,0, et (2) un polymère vinylamidique, hydrosoluble, cationique, glyoxalaté, d'un poids moléculaire d'environ 500 à environ 6000, contenant suffisamment de substituants réagissant aux substituants du type glyoxal et de substituants du type glyoxal pour être thermodurcissable, le rapport des substituants du type glyoxal aux substituants vinylamides dépassant environ 0,1:1,0.
