There is known the method for dyeing organic fiber from DE 41 33 977 A1, its dope dyeing (spin dyeing) being different from prior art is that it uses the aqueous solution of cationic polymer and then uses the water slurry of pigment to dye a small amount of fiber.In the case of any possible, the particle size for the particle dyeed should < 10 μm.
There is known from DE 37 19 48 A and manufacture the method that the ring of light produces colored fibre.Be embedded into the paper in it by dry colored fibre, these colored fibres make paper stamp color, thus the ring of light is formed in around colored fibre, can be easy to like this remove fiber.
There is known the safety paper of band colored fibre from EP 1 268 935 B1, different luminous colored fibres is embedded into, and object is encoded in the different subregions of paper.Luminescent substance can be introduced in colored fibre or only be applied on their surface.The characteristics of luminescence is such as the die-away time of emission wavelength or luminous rays.
A shortcoming of this prior art is that the types of patterns introduced is very limited.Strip pattern is only disclosed in EP 1 268 935B1.In addition, the method manufacturing this safety paper can not for the manufacture of the file based on plastics, because colored fibre loosely to be arranged on hard frosting therefore by Arbitrary distribution and can not the pattern of replication application.
