Se conocen polímeros según la fórmula I en el campo de los detergentes para el lavado de ropa, y se usan normalmente como agentes quelantes, como por ejemplo en el documento GB-A-1.597.756. Los polímeros de policarboxilato preferidos pueden clasificarse en varias categorías. Una primera categoría pertenece a la clase de polímeros de policarboxilato copoliméricos que, formalmente al menos, se forman a partir de un ácido policarboxílico insaturado tal como ácido maleico, ácido citracónico, ácido itacónico y ácido mesacónico como primer monómero, y un ácido monocarboxílico ¡nsaturado tal como ácido acrílico o un ácido acrílico de alquilo C1-C4 alfa como segundo monómero. Por tanto, haciendo referencia a la fórmula I, polímeros de policarboxilato preferidos de este tipo son aquéllos en los que X es CHO, R3 es H o alquilo C1-4, especialmente metilo, p es desde aproximadamente 0,1 hasta aproximadamente 1,9, preferiblemente desde aproximadamente 0,2 hasta aproximadamente 1,5, n tiene un promedio de desde aproximadamente 10 hasta aproximadamente 1500, preferiblemente desde aproximadamente 50 hasta aproximadamente 1000, más preferiblemente desde 100 hasta 800, especialmente desde 120 hasta 400 e YPolymers according to formula I are known in the field of laundry detergents, and are normally used as chelating agents, such as in GB-A-1,597,756. Preferred polycarboxylate polymers can be classified into several categories. A first category belongs to the class of copolymeric polycarboxylate polymers that, formally at least, are formed from an unsaturated polycarboxylic acid such as maleic acid, citraconic acid, itaconic acid and mesaconic acid as the first monomer, and a saturated monocarboxylic acid such as acrylic acid or a C1-C4 alpha alkyl acrylic acid as a second monomer. Thus, with reference to formula I, preferred polycarboxylate polymers of this type are those in which X is CHO, R3 is H or C1-4 alkyl, especially methyl, p is from about 0.1 to about 1.9 , preferably from about 0.2 to about 1.5, n has an average of from about 10 to about 1500, preferably from about 50 to about 1000, more preferably from 100 to 800, especially from 120 to 400 and Y

Ejemplo 1Example 1
Se mezcló el colorante violeta disolvente 13 en tensioactivo no iónico (7EO) para formar una disolución al 0,5% en peso. A esto se le añadió la sal de [nitrolotris(2,1-etanodiiloxi)]tris[propanol] de violeta directo 9, DV9, (de Ciba Speciality Chemicals). Se añadió el no iónico al vehículo en una mezcladora de alto cizallamiento. Tras esto se añadió el aglutinante, Sokalam CP5 (de BASF). Cuando fue apropiado, se añadió polivinilpirrolidona, PVP, a la disolución no iónica de partida.Solvent violet dye 13 was mixed in nonionic surfactant (7EO) to form a 0.5% solution by weight. To this was added the salt of [nitrolotris (2,1-ethanediyloxy)] tris [propanol] of direct violet 9, DV9, (from Ciba Specialty Chemicals). The non-ionic was added to the vehicle in a high shear mixer. After this the binder, Sokalam CP5 (from BASF) was added. When appropriate, polyvinylpyrrolidone, PVP, was added to the non-ionic starting solution.
Se secaron los gránulos resultantes en un horno a 353 K, finalmente se tamizaron para dar gránulos en el intervalo de tamaño de 500 a 1400 micrómetros.The resulting granules were dried in a 353 K oven, finally screened to give granules in the size range of 500 to 1400 micrometers.

Se añadieron por separado los gránulos del ejemplo 1 a un polvo de detergente (20% de sulfonato de alquilbenceno lineal, 30% de carbonato de sodio, 40% de cloruro de sodio, el resto componentes minoritarios que incluyen fluorescente y humedad), al 2% en peso. Se rociaron 10 g del polvo sobre un fragmento de 25 por 25 cm de laminado de algodón blanco, sumergida en 1 cm de agua desmineralizada. Se empapó la tela durante 90 minutos, luego se aclaró y secó meticulosamente. Se repitió cada experimento cuatro veces. Se compararon las telas empapadas con gránulo 1 y 2, y se compararon el gránulo 3 y 4, ya que tenían niveles equivalentes de DV9. Se clasificaron las ocho telas de cada comparación en cuanto al grado de tinción/manchado de colorante. La tela con la menor tinción/manchado recibió una puntuación de 1, aquélla con el segundo nivel de tinción más bajo una puntuación de 2, y así sucesivamente, de modo que la tela más teñida/manchada tuvo una puntuación de 8.The granules of Example 1 were added separately to a detergent powder (20% linear alkylbenzene sulphonate, 30% sodium carbonate, 40% sodium chloride, the remaining minor components including fluorescent and moisture), at 2 % in weigh. 10 g of the powder was sprayed on a 25 by 25 cm fragment of white cotton laminate, immersed in 1 cm of demineralized water. The cloth was soaked for 90 minutes, then rinsed and dried thoroughly. Each experiment was repeated four times. Fabrics soaked with granule 1 and 2 were compared, and granule 3 and 4 were compared, since they had equivalent levels of DV9. The eight fabrics of each comparison were classified for the degree of dye staining / staining. The fabric with the lowest staining / staining received a score of 1, the one with the second lowest staining level a score of 2, and so on, so that the most dyed / stained fabric had a score of 8.
Se comparó entonces la puntuación total a lo largo de las 4 telas para cada gránulo:The total score was then compared along the 4 fabrics for each granule:
Gránulos que contienen el 0,20% en peso de DV9Granules containing 0.20% by weight of DV9
Gránulo 1 (sin PVP) puntuación total = 24
Granule 1 (without PVP) total score = 24
Gránulo 2 (PVP) puntuación total = 12
Granule 2 (PVP) total score = 12
Gránulos que contienen el 0.08% en peso de DV9 5Granules containing 0.08% by weight of DV9 5
Gránulo 3 (PVP) puntuación total = 11
Granule 3 (PVP) total score = 11
Gránulo 4 (sin PVP) puntuación total = 25
Granule 4 (without PVP) total score = 25
Los gránulos que contienen el polímero de inhibición de transferencia de colorante muestran niveles reducidos de manchado/tinción.Granules containing the dye transfer inhibition polymer show reduced staining / staining levels.
