Definitions

  • the invention relates to a paper or a cardboard with a coating applied by a coating process, which is formed from a mineral pigment, latex, a starch derivative and an aqueous composition comprising casting coating aids known per se in the usual amount.
  • the invention also relates to a method for producing the specified paper or cardboard and its use.
  • DE-26 19 848 AI describes a non-proteinaceous binder composition for the cast coating of paper, in which the binder composition comprises modified starch and two carboxylated styrene-butadiene latices, which differ in their degree of carboxylation.
  • a pigment mixture given by way of example consists of 85 parts made of calcium carbonate and about 15 parts of a coating clay.
  • the known composition may contain a pentaerythritol ester resin and the dispersing and separating agents which are customary per se.
  • DE-26 19 848 AI aims to replace casein as the main binder component for coating colors to be processed in the coating process and thus to avoid its disadvantages, in particular the high costs and the limited availability. At the same time, however, both a good release property of the dried coating color from the high-gloss cylinder and a high-quality paper sheet which has excellent printability, sheet gloss and water resistance should be achieved.
  • DE-23 02 044 C2 also refers to the disadvantages of using casein as a binder and therefore provides for a mixture of two latices as a binder, one latex not being alkali-soluble or swellable and the other latex being alkali-swellable or soluble.
  • the aqueous coating mass must be kept at a pH of ⁇ 7.0 and the coated paper web must be conveyed in cast holding rollers with a chrome-plated surface which contain a bath of boiling water.
  • the coating composition applied to the paper web is first partially dried, but no gelation occurs and fed to the casting holding drum filled with boiling water while the paper web is pressed against the surface of the casting holding drum with a pressure roller. A water bath forms in the nip formed between the casting holding drum and the pressure roller.
  • casein as a natural product is subject to not inconsiderable quality fluctuations.
  • Another disadvantage of casein is its sensitivity to bacteria.
  • the qualitative requirements for cast-coated papers or cardboard types have become ever stricter; in particular, good wet scrub resistance and good gloss retention are required to an ever increasing extent. The demands made are to be seen from the point of view of changed printing techniques as well as modern warehousing and sales methods.

  • latex binders to be used according to the invention with a glass transition temperature> 18 ° C. and a starch ether are obtained by adding those to be used according to the invention
  • Crosslinking aids are excellently crosslinked, so that, in cooperation with the pigments provided according to the invention, a cast coating is formed with excellent adhesion to the surface of paper or cardboard, which has excellent printing ink adhesion, in particular also of aqueous or water-thinnable printing inks.
  • the coating color is not impaired by heating the coating ink sump when the web enters the high-gloss cylinder.
  • a further advantage when using the crosslinking aids to be used according to the invention results from the fact that no harmful vapors escape, as z. B. in formaldehyde-releasing crosslinking agents during the Drying process is the case.
