Abstract
La presente invencion se refiere a ciertos compuestos de piperidina que tienen la formula (I) los cuales se usan para proteger pigmentos o mezclas de pigmentos, naturales o sintéticos, orgánicos o inorgánicos, en substratos naturales o sintéticos, poliméricos o prepoliméricos, contra los efectos negativos del calor y/o de la luz, en la resistencia a la luz o en la estabilidad del color, en particular contra cambios del color o contra la decoloracion inducida por la luz. En la formula (I), R1 representa hidrogeno, hidroxilo, alquilo de bajo peso molecular, alcoxi o acilo de bajo peso molecular; R2 representa un residuo de carácter aromático, con uno o dos nucleos, y substituyentes opcionales, R3 representa oxígeno, -NH- o -N(alquilo de 1 a 4 átomos de carbono)-; y todos los R8 representan independientemente hidrogeno o metilo. También se describe una composicion de mezcla madre con al menos un compuesto de piperidina de formula (I), opcionalmente al menos un pigmento inorgánico u orgánico, y un material natural o sintético que es idéntico a, o compatible con, el substrato natural o sintético, polimérico o prepolimérico, que se va a pigmentar. En un proceso para proteger pigmentos o mezclas de pigmentos, orgánicos o inorgánicos, en substratos sintéticos, poliméricos o prepoliméricos, contra los efectos negativos del calor y/o de la luz, en la resistencia a la luz o en la estabilidad del color, en particular contra los cambios de color o contra la decoloracion inducida por la luz, se adiciona, una cantidad de al menos un compuesto de piperidina de formula (I), suficiente para propositos de estabilizacion, como tal o en la forma de una composicion de mezcla madre, al pigmento o mezcla de pigmentos que se va a estabilizar , o al substrato natural o sintético, polimérico o prepolimérico, que contiene el pigmento o mezcla de pigmentos.
