    Abstract: The invention relates to a method for improving printability on paper or pap er products with the aid of an ink-jet printing method. Said method consists in treating paper or paper products by aqueous solutions containing cationic polymers whose charge density is equal or higher than 3 mVal/g and which are used as a sole treating agent in the aqueous solution. The cationic polymer is applied to a paper or paper product surface, whereby the quantity thereof ranges from 0.05 to 5.0 g/m 2. The use of said cationic polymers in order to improve the printability by ink-jet printing on paper or paper products is also disclosed.

    Abstract: Paper, board and cardboard are produced by a process in which a paper stock is drained in the presence of condensates of basic amino acids with sheet formation. In particular, homo- and cocondensates of lysine and the crosslinked condensates obtainable therefrom by reaction with crosslinking agents are used in amounts of from 0.01 to 5% by weight, based on dry paper stock, as a means of increasing the dry and wet strength and the absorptivity of paper, for fixing anionic dyes and interfering substances in the paper, for increasing the drainage rate and the retention as well as the efficiency of synthetic anionic and cationic retention aids in the production of paper, board and cardboard by draining a paper stock with sheet formation.
