摘要
A colourant additive composition is described as well as its use for addition to thermoplastic moulding compositions, for example thermoplastic moulding compositions comprising polyesters, such as polyethylene terephthalate. The colourant additive composition comprises at least one reducible colourant. The colourant additive composition is suitable for use in thermoplastic moulding compositions for making, for example, bottles which can be recycled by a recycling process which includes the step of subjecting the recycled material to reducing conditions sufficient to cause a desirable change of colour.
