The 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 material 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.

La présente invention concerne une nouvelle composition destinée à la fabrication de structures planes, à base d'une matière amylacée cationique et d'une matière amylacée sulfonée, par exemple sulfocarboxylée. La composition peut se présenter sous la forme d'un mélange solide pulvérulent ou d'une suspension aqueuse dans lesquels les deux matières amylacées se présentent à l'état granulaire, gonflé ou non. Elle peut également se présenter sous la forme d'une colle pouvant ou non contenir des structures granulaires, gonflées ou non et/ou des complexes associant les deux matières amylacées. Ces complexes floculent et précipitent généralement lors de l'étape de solubilisation qui peut avantageusement consister en une étape de cuisson continue ou discontinue. L'application des compositions revendiquées et des complexes floculés/précipités qu'elles peuvent contenir permet de conférer aux structures planes, en particulier au papier, carton ou films, des caractéristiques physiques répondant parfaitement aux exigences de la pratique actuelle. En vue du traitement interne du papier ces compositions peuvent notamment être introduites dans la masse fibreuse, en une ou plusieurs fois, à raison de 2 à 12 % en poids (sec/sec).
