PROCEDIMIENTO MEJORADO PARA EL BLANQUEO DE TELAS TEXTILE MEDIANTE BAÑOS ACUOSO QUE CONTIENEN UN AGENTE FOTOSENSIBILIZACION DE ALUMINIO FTALOCIANINA HIDROSOLUBLE CON IRRADIACION MEDIANTE LUZ VISIBLE Y/O INFRARROJO, EN PRESENCIA DE OXIGENO

摘要

A process for bleaching textiles which comprises treating stained textiles in an aqueous bath containing at least one water-soluble aluminium phthalocyanine, under irradiation with light and in the presence of oxygen, while either irradiating the bleaching bath direct or subsequently irradiating the moist textiles outside the bath, as well as water-soluble aluminium phthalocyanines containing detergent compositions are described.
