본 발명은 (a) 1.5 meq/g 중합체 이상의 총 함량으로 1 차 아미노기 및/또는 아미딘기를 갖는 중합체, 및 (b) 상기 중합체의 1 차 아미노기와 아미딘기의 총량을 기준으로 0.01 내지 50 몰%의 1,4-사이클로헥산다이온(b)을 포함하며, pH가 6 이하인, 수성 조성물에 관한 것이다. 본 발명은 또한 이의 고화제로서의 용도, 종이 및 보드의 제조 방법, 상기 수성 조성물의 용도 및 또한 그렇게 하여 수득된 종이 및 보드에 관한 것이다. The invention relates to an aqueous composition containing (a) polymers having primary amino groups and/or amidine groups with a total content of said groups of ≥1.5 meq/g polymer and (b) 0.01 - 50 mol-% 1,4-cyclohexandion (b) based on the total amount of primary amino groups and amidine groups of the polymers. The aqueous composition has a pH-value ≤6. The invention also relates to the use thereof as a solidifying agent and to a method for producing paper and cardboard, to the use of the aqueous composition and to the thus produced paper and cardboard.
