The novel AOX-free process for imparting wet strength to paper with water-dispersible polyisocyanates is distinguished by a good wet-strength effect, even under mild drying conditions, and does not affect the activity of optical brighteners used at the same time.

Process for imparting wet strength to paper

Paper finishing aid

Water-dispersible polyisocyanates

Use of polyaspartic acid amides as leather auxiliary products

The invention relates to a new process for the preparation of cellulose-containing material provided with a dry-strength and wet-strength finish and/or sized, characterised in that the cellulose-containing material is treated with a water-dispersible polyisocyanate mixture (I), which contains tertiary amino and/or ammonium groups, optionally polyether units and optionally hydrophobic groups.

Chlorine-free multifunctional resins for paper finishing

Process for the production of optionally wood-containing cellulose-containing sheet-like structures, such as paper, pasteboard and card, which have been given a dry strength and/or wet strength treatment and have improved whiteness, using water-dispersible isocyanates, wherein the water-dispersible isocyanates:

Process for the production of cellulose-containing sheet-like structures

Process for fixing anionic interfering substances in papermaking process by the addition of cationic polycondensation products obtained by reacting

Process for fixing disruptive substances in papermaking

The invention relates to a new process for the preparation of cellulose-containing material provided with a dry-strength and wet-strength finish and/or sized, characterized in that the cellulose-containing material is treated with a water-dispersible polyisocyanate mixture (I), which contains tertiary amino and/or ammonium groups, optionally polyether units and optionally hydrophobic groups.

Water-soluble crosslinkable compounds obtainable by reaction of reactive products which contain halogenohydrin groups and have been obtained by reacting polyamines and epihalogenohydrin or 1,3-dihalogeno-2-hydroxy-propane with inorganic bases and subsequently reacting the resulting products with inorganic acids and/or organic acids, can be used as pigment binders and/or crosslinking agents in textile printing pastes.

Pigment printing on fibre materials

The invention relates to new cleavable surface-active silane derivatives of the formula ##STR1## in which R.sub.1, n, R.sub.2, R.sub.3, X, m and R.sub.4 have the meaning given in the description, and furthermore processes for the preparation of these silane derivatives and the use of these compounds as surfactants.

Preparation of emulsions or other multiphase formulations

Crosslinkable compounds obtainable by reaction of water-soluble mono- or polyamines with 2,3-epoxypropyl sulphonates or 2-hydroxypropyl 1,3-bis-sulphonates or their mixtures with up to 15 mol % of an epihalogenohydrin or diyhalogenohydrin are used for imparting wet strength to paper.

Nitrogen-containing polymeric compounds

Crosslinkable compounds obtainable by reaction of water-soluble mono- or polyamines with 2,3-epoxypropyl sulphonates or 2-hydroxypropyl 1,3-bis-sulphonates or their mixtures with up to 15 mol % of an epihalogenohydrin or dihalogenohydrin are used for imparting wet strength to paper.
