    Abstract: A method is provide for dyeing a non-cellulosic organic material with a dye, preferably a vat dye, comprising (a) treating the material with a dye in the presence of a reducing agent and an alkali and (b) oxidising the treated material produced in step (a) characterised in that the concentration of reducing agent used in step (a) is increased above that used for conventional vat dyeing such that the resultant dyed material has a lightfastness of 5 or more by BS1006 B01 and B02 (1978) and/or has a washfastness of 5 or more by British Standard Test BS1006 CO6.C2 (1981). Preferably the step (a) is carried out in the presence of an alkali in concentration of greater than 0.1 molar, more preferably a concentration of 0.2 molar or more and most preferably greater than 1 molar.The method provides vat dyed non-cellulosic organic materials having a reflectance of infra-red light of wavelength 400 nm to 680 nm of less than 15%.

    Abstract translation: 提供了用染料，优选还原染料染色非纤维素有机材料的方法，其包括（a）在还原剂和碱的存在下用染料处理该材料，和（b）氧化所生产的经处理的材料 在步骤（a）中，步骤（a）中使用的还原剂的浓度增加到高于常规瓮染色所用的还原剂的浓度，使得所得染色材料通过BS1006 B01和B02（1978）具有5或更高的耐光性和 /或英国标准试验BS1006 CO6.C2（1981）具有5或更高的耐洗涤性。 优选地，步骤（a）在浓度大于0.1摩尔，更优选浓度为0.2摩尔以上，最优选大于1摩尔的碱存在下进行。 该方法提供了具有小于15％的波长为400nm至680nm的红外光的反射率的大众染色的非纤维素有机材料。
