Process for the production of dried single-layer or multi-layer paper, comprising the steps for a single-layer paper Dewatering a first aqueous fiber suspension, which has a dry matter content between 0.1 wt.% And 6 wt.%, on a first sieve, whereby a first fibrous sieve, which has a dry matter content between 14 wt.% and 25 wt.%, arises, (D-I) Dewatering the first fibrous web by pressing, thereby creating a partially dehydrated first fibrous web, (E-I) Spraying the partially dewatered first fibrous web on at least one surface side with a spray solution or spray suspension, resulting in a sprayed partially dewatered first fibrous web, (F-I) Dewatering the sprayed partially dehydrated first fibrous web by applying heat to form the dried single-layer paper. or containing the steps for a multilayer paper Dewatering a first aqueous fiber suspension, which has a dry matter content between 0.1 wt.% And 6 wt.%, on a first sieve, whereby a first fibrous sieve, which has a dry matter content between 14 wt.% and 25 wt.%, arises, Dewatering a second aqueous fiber suspension, which has a dry matter content between 0.1 wt.% And 6 wt.%, on a second sieve, whereby a second fibrous sieve, which has a dry matter content between 14 wt.% and 25 wt.-%, arises, Assembling the first fibrous web to the second fibrous web such that the two fibrous webs touch each other on an entire surface side, thereby resulting in a layer compound, (D-2) Dewatering the layer composite by pressing, resulting in a partially dewatered layer composite, (E-2) Spraying the partially dewatered layer composite on at least one surface side with a spray solution or spray suspension, resulting in a sprayed layer composite, (F-2) Dehydrating the sprayed layer compound by applying heat means to form the dried multilayer paper, wherein the spray solution or spray suspension contains (e-a) Water (e-b) at least one water-soluble polymer P, which can be obtained by polymerizing (i) 40 to 85 mol% of a monomer of Formula I in which R 1 = FH C 1 -C 6 -Alkyl, (ii) 15 to 60 mol% of one or more ethylenically unsaturated Monomers which are different from a monomer of formula I, the total amount of all monomers (i) and (ii) being 100 mol%, and optionally by a subsequent partial or complete hydrolysis of the units of the monomers of formula polymerized into the polymer P to form primary amino or amidine groups, wherein the proportion of water is at least 75% by weight, based on the spray solution or the spray suspension.
