摘要： This invention relates to a novel composition for the production of planar structures, whereby said composition is based on a cationic amylaceous material and a sulphonated amylaceous such as sulphocarboxylate. The composition can exist in the form of a pulverulent solid mixture or an aqueous suspension in which both amylaceous materials take the form of granules which are swollen or unswollen. Said composition can also exist in the form of an adhesive which can or cannot contain granular structures which are swollen or unswollen and/or complexes which associate both amylaceous materials. Said complexes flocculate and precipitate generally during the solubilization stage which can advantageously consist of a continuous or discontinuous curing stage. The use of said compositions and flocculated/precipitated complexes that they can contain allows planar structures, especially structures made of paper, cardboard or films, to be provided with physical characteristics that meet the needs of current usage in every way. Said compositions can be introduced into a fibrous mass either on one occasion or on a number of occasions at a rate of 2-12 wt. % (sec/sec) for internal treatment of paper.
