  • Multifunctionally usable coating dispersion for printing substrates
    Publication number: 20060235129
    Abstract: The disclosure relates to a coating dispersion for coating printing substrates, especially paper and paperboard. Said dispersion is constituted of at least one defined percentage of water, a defined percentage of a swellable phyllosilicate and a defined percentage of a cross-linking agent. The cross-linking agent forms a bond with at least one functional group of the phyllosilicate as well as with at least one functional group of the printing substrate. The invention also relates to a method for producing a coated printing substrate onto which a coating dispersion is mechanically applied and dried, whereby the coating dispersion comprises at least the aforementioned components.

  • Surface finishing of paper or board, and agent for this purpose
    Publication number: 20050167064
    Abstract: Surface finishing of paper or board by applying an aqueous solution (Lw) of a surface-finishing active ingredient (W) to a hydrophilic paper or board sheet (B), in which (W) consists of (W1) polyethylene glycol with an average molecular weight {overscore (M)}w of>1500 and optionally at least one further additive which is a further finishing additive and/or a formulation additive, and the paper or board sheet surface-treated with (Lw) is fed through smoothing rolls and dried, the surface-finished paper and surface-finished board (Bw) produced, surface finishing agent for this purpose, and the use of the surface-finished paper or board as substrate for graphic processing.
