Composiciones de pintura con pigmentos coloreados que presentan un mayor poder de cobertura, una mayor resistencia al rayado y propiedades de limpieza fácil

Una composición de pintura pigmentada con color que comprende un disolvente o una mezcla de disolventes ya.) respecto a la formulación total, del 1% al 80% en peso de un polisilazano de fórmula (1) -(SiRR-NR)n- (1) y b.) respecto a la formulación total del 1% al 15% en peso de uno o más pigmentosdonde R, R y R son iguales o diferentes e independientemente entre sí representan hidrógeno o un restoalquilo, arilo, vinilo o (trialcoxisilil)alquilo dado el caso sustituido, siendo n un número entero y teniendo n unadimensión tal que el polisilazano presenta un peso molecular promedio numérico de 150 a 150.000 g/mol The present invention is directed to a color-pigmented paint composition with high hiding power, comprising a solvent or a solvent mixture and a.) based on the total formulation, 1% to 80% by weight of a polysilazane of the formula (1) -(SiR'R''-NR''')n-(1) and b.) based on the total formulation 1% to 15% by weight, particularly 2% to 8% by weight, of one or more pigments wherein R', R'', and R''' are alike or different and independently of one another are hydrogen or an unsubstituted or substituted alkyl, aryl, vinyl or (trialkoxysilyl)alkyl radical, n being an integer and n having a magnitude such that the polysilazane has a number average molecular weight of 150 to 150 000 g/mol.
