- EP-A-0 275 851 describes an aqueous dispersion, the dispersed phase a homogeneous mixture of resin material and a synthetic sizing agent, preferably ketene dimerate, contains as well as a polyaluminium compound at least four aluminum atoms.
- a synthetic sizing agent preferably ketene dimerate
- DE-A-43 06 557 describes a composition for surface sizing of paper and cardboard containing an aqueous Dispersion of 1 to 40 wt .-% rosin resin and 1 to 5% by weight protective colloid and / or surfactant.
- rosin resin are called tall, balm or root resin.
- a cationic Polymers are polyacrylamide, urea derivatives, Called acrylic acid derivatives, etc.
- US-A-4,522,686 describes a sizing agent for mass and surface sizing for paper, which is a dispersion a ketene dimer, a reinforced resin and water-soluble, nitrogen-containing cationic dispersants contains.
- EP-A2-0 357 866 describes a cationic sizing agent for paper, which also has an excellent sizing effect for surface sizing.
- the sizing agent consists of a stable, aqueous, colloidal dispersion Solution of a salt of a copolymer consisting of N, N-dimethylaminoalkyl acrylate, Meth / acrylic acid ester of a fatty alcohol and concentrations of methacrylate and methacrylic acid.
- EP-A-0 257 412 also describes a sizing agent for Paper containing a dispersion of copolymers Acrylonitrile and acrylic acid esters of an alcohol. This composition can be used as surface sizing agent for paper will.

- the object of the invention is surprisingly simply achieved by a means for gluing paper, cardboard and cardboard consisting of 5 to 75% by weight dispersions of alkylketene dimers and 25 to 95% by weight of a cationic resin glue, the cationic resin glue being made from a rosin -Dispersion and polyaluminium hydroxychlorides.
- the agent can be used both as a mass and as a surface sizing agent.
- the agent is liquid and is in dispersion form.
- objects of the invention are the method according to claim 2 and the use according to claim 3.
- Rosin resins such as tall resin, Balsam resin or root resin used, the resin can be partially saponified or unsaponified.
- rosin dispersions As a rosin dispersion, commercially available ones are preferred Dispersions used like the rosin resin Kentosol AP® according to EP-B-0 200 002. For these dispersions either Conventionally unreinforced rosin resin dispersions or using the conventionally reinforced resin glue dispersions, those made from maleic anhydrite or fumaric acid modified Rosin or hydrocarbon resin with additives made of protective colloids or surface-active substances will. These commercial rosin dispersions with a solids content of 10 to 50% by weight have the advantage that they are made of natural resin and thus are environmentally friendly and recyclable. Compared to the polymers or synthetically produced sizing agents they are characterized by a significantly better price / performance ratio out.
- alkylbenzyl sulfonates Alkylphenol polyglycol ethers, alkylphenol polyglycol sulfonates, Phosphoric acid esters, alkyl polyglycol sulfosuccinates can be used to disperse the rosin resin.
