摘要： According to the present invention, there is provided an anionic nanocomposite for use as a retention and drainage aid in papermaking obtainable by a process comprising the steps of:

a) providing a sodium silicate solution;
b) adding an anionic polyelectrolyte to the sodium silicate solution; and
c) combining the sodium silicate solution containing the anionic polyelectrolyte with silicic acid, wherein the silicic acid is combined with the sodium silicate solution containing the anionic polyelectrolyte by adding the silicic acid to the solution or wherein the silicic acid is combined with the sodium silicate solution containing the anionic polyelectrolyte by generating the silicic acid in situ by adding a solution of sodium silicate, also containing an anionic polyelectrolyte or the two can be added separately, to a weak acid ion exchange resin in the hydrogen form.

摘要： The present invention provides as a first feature thereof a process for producing paper which is characterized in that material paper is passed through a nip provided by a metal roll and another metal roll under a linear pressure of 200 to 2500 kg/cm.
The present invention provides as a second feature thereof a paper which is characterized in that the paper is produced by forming a coating layer containing a moisture-proof resin is formed on both surfaces of material paper before or after the material paper is passed through a nip provided by a metal roll and another metal roll under a linear pressure of 200 to 2500 kg/cm.
The present invention provides as a third feature thereof a paper which is characterized in that the paper is produced by incorporating an interfiber crosslinking agent for cellulose into material paper, and thereafter passing the material paper through a nip provided by a metal roll and another metal roll under a linear pressure of 200 to 2500 kg/cm.
The present invention provides as a fourth feature thereof a process for producing paper comprising at least two laminated sheets of paper, the process being characterized by passing at least two sheets of material paper through a nip provided by a metal roll and another metal roll under a linear pressure of 500 to 2500 kg/cm.
摘要翻译：本发明的第一个特征在于提供一种纸的制造方法，其特征在于，在200〜2500kg / cm 2的线压力下，将材料纸通过由金属辊和另一金属辊提供的辊隙。本发明的第二特征在于提供一种纸，其特征在于，通过在材料纸通过辊隙之前或之后形成在材料纸的两个表面上形成包含防湿树脂的涂层来制造纸张由金属辊和另一金属辊在200至2500kg / cm 2的线性压力下提供。本发明的第三个特征是提供一种纸，其特征在于，通过将纤维素的纤维间交联剂加入材料纸中，然后使材料纸通过由金属辊和另一金属辊提供的辊隙在200至2500kg / cm的线性压力下。本发明的第四个特征在于提供了一种包括至少两层叠纸的纸的生产方法，该方法的特征在于使至少两张材料纸通过金属辊和另一金属辊所提供的压区线性压力为500〜2500kg / cm。

摘要： There are reacted together:

(a) a polyalkylenepolyamine with 2 primary and one secondary amino group, and optionally an aliphatic diamine;
(b) an alicyclic dibasic carboxylic acid or its ester or anhydride, and/or the reaction product (polyester) of such acid with a glycol, and optionally another dibasic arboxylic acid;
(c) a urea, and
(d) (i) a monoaldehyde or polyaldehyde or (ii) an alkylating agent which can be of 6 defined types, preferably epichlorohydrin, or both (i) and (ii) if (i) is formaldehyde and/or glyoxal.

Preferably (d) is reacted with the product of (a), (b) and (c).
An aqueous solution of the resultant resin is mixed with pigment and water-soluble binder, and the composition is coated on a paper sheet to provide coated paper having good water resistance and ink receptivity and low evolution of formaldehyde.
