The composition comprises one of a pair of a colorformer and an activator which react when mixed to produce a spectral response. The textile product is authenticated as genuine by applying the other of the pair of the colorformer and activator to at least one portion of the at least one thread to produce the spectral response. The textile product may be a thread or a woven label.
