Previously cross-linked silicone elastomer particles with an organopolymer sheath are used as constituents for formulating water lacquer compositions based on water-soluble or water-dilutable binders. The silicone elastomer particles contain: (a) 5 to 95 % by weight, with respect to the total weight of the copolymer, of a nuclear polymer of general formula (R2SiO2/2)x.(RSiO3/2)y.(SiO4/2)z, in which x = 5 to 99.5 % by mole, y = 0.5 to 95 % by mole, z = 0 to 30 % by mole, and (b) 5 to 95 % by weight, with respect to the total weight of the copolymer, of a sheath made of an organopolymer from mono- or polyethylenically unsaturated monomers; and R stands for the same or different monovalent alkyl or alkenyl radicals with 1 to 6 C atoms, aryl radicals or substituted hydrocarbon radicals.

L'invention concerne l'utilisation de particules d'élastomères à silicone préréticulées à enveloppe organopolymère s'utilisant comme constituant de formulation de peintures aqueuses à base de liants solubles ou diluables dans l'eau. Les particules d'élastomère à silicone contiennent a) entre 5 et 95 % en poids par rapport au poids global du copolymérisat, d'un polymère nucléaire de la formule générale (R¿2?SiO¿2/2?)¿x?.(RSiO¿3/2?)¿y?.(SiO¿4/2?)¿z? dans laquelle x représente entre 5 et 99,5 % en mole, y entre 0,5 et 95 % en mole, z, entre 0 et 30 % en mole, et b) entre 5 et 95 % en mole, par rapport au poids global du copolymérisat, d'une enveloppe en organopolymère de monomères insaturés éthyléniquement une ou plusieurs fois, et R désigne des restes alkyle ou alkényle monovalents identiques ou différents ayant entre 1 et 6 atomes de C, des restes aryle ou des restes hydrocarbures substitués.
