Abstract: The invention concerns the use as sticking agents, in formulations to be used in the presence of an aqueous solution, of at least a compound with elongation viscosity not less than twice that of water and a flow viscosity not more than six times that of water; said viscosity levels being measured for compound concentration levels ranging between 0.05 and 3 g/l.

Abstract: The invention concerns an aqueous biocide system comprising: at least one water-soluble or water-dispersible biocidal agent, and at least a polyorganosiloxane with water-soluble or water-dispersible functions. The invention also concerns the use of the system for disinfecting hard surfaces, or a method for disinfecting hard surfaces using the system, with controlled release of the biocide when contacted with an aqueous medium of a hard surface whereon the aqueous medium has been deposited and dried.

Abstract: A water-soluble or water-dispersible copolymer comprising: at least one polyoxyalkylene (POA) unit; and at least one sulfonated polyamide (PAS) unit; the quantity of SO3M functions, expressed as the mass of SO3− function, in said (PAS) unit or units is such that it represents at least 0.1% of the total mass of said copolymer; the total (POA) units/total (PAS) units mass ratio is 95/5 to 30/70/ the number of amine functions —NH2 present in said copolymer is at most 80 milliequivalents per kilogram of copolymer; the number of carboxyl functions —COOH present in said copolymer is at least 80 milliequivalents, preferably at least 100 milliequivalents per kilogram of copolymers.

Abstract: The invention relates to composite films consisting of a semicrystalline polyester substrate film, free from filler and with a roughness Ra lower than or equal to 0.01 .mu.m, carrying on at least one of its faces a coating based on a modified polymer obtained by polymerization of one or more acrylic monomers in the presence of a water-dispersible sulphonated copolyester.

Abstract: Oriented composite polyester films with improved adherence in respect of the various final coatings, comprising on at least one of their faces a primary adherence coating formed by co-extrusion of a common crystallizable polyester and of a copolyester with oxysulfonyl groups comprising, for 100 moles of recurrent units of dicarboxylic acid: a) from 78 to 93 moles of terephthalate units; b) from 2 to 5 moles of units derived from an aromatic diacid with one or a number of oxysulfonyl groups; c) from 5 to 17 moles of units derived from at least one alcanediacarboxylic acid comprising from 4 to 15 carbon atoms. These composite films have applications as a final coating support used in packaging, the graphic arts or metal coatings.

Abstract: The invention relates to orientated composite polyester films carrying, on at least one face, a coating intended to improve the slip properties, consisting of a graft polymer comprising a backbone derived from a polyester containing sulphonyloxy groups and grafts of polymer units derived from at least one ethylenically unsaturated monomer and at least one ethylenically unsaturated organosiloxane.The composite polyester films according to the invention are very particularly suitable for the production of magnetic tapes.
