PROBLEM TO BE SOLVED BY THE INVENTION The prior art methods described enable, in particular: - a strongly and permanently adherent metallization of plastics, which is completely satisfactory optically and mechanically; It was not possible to satisfactorily meet the challenges faced in all cases. Support chemistry 1
Although the adhesion of the metal layer by iJ 6 or alteration is improved, it does not completely satisfy the prevailing requirements, above all regarding the effect of moisture. Moreover, in various cases the support becomes wet and the optical properties are thereby impaired. Mechanical roughening and lacquering also often impair optical properties very strongly. 1. Means for solving the problem In order to apply a gold coating to the plastic support, especially in the case of one-phase plastic supports, it is possible to completely or at least cover the surface area for metallization with the polymer P. Suitably, the polymer is composed of amino group-containing derivatives of acrylic acid and/or methacrylic acid, at least up to 6 ox (relative to the vehicle body P) in terms of O1 concentration. It was discovered that The plastic carrier according to the invention, which has a surface area consisting of the polymer P or of the undercarriage P, is characterized by the fact that the plastic carrier according to the invention has a surface area consisting of the polymer P or of the undercarriage P. treatment with a carboxylic acid or its derivative, optionally followed by treatment with a photosensitizer, e.g. a metal salt solution such as 5nC112, before and after wet total assembly without application of a di flow, optionally followed by electrolytic dissociation.

Preparation of the polymer P (see Section 1.g.) From the preparation of the polymer P, the radical polymerization of a monomer can be carried out in close reliance on the prior art.

Following the metallization, another repellent membrane could be applied, for example by fitting.The analogy here is that if the metallized surface is used as an anode and the surface is connected as an anode, then electroplating of copper The polymer P is therefore especially suitable for the production of encapsulated objects with a special structural boundary between the support material and the membrane. In addition, the method according to the invention is also suitable for the production of other high-temperature metallized materials, such as linen, for example - as mentioned at the outset.

ADVANTAGES OF THE INVENTION The composite material P used according to the invention is eminently suitable as a support for the fixation of metal coatings and is in this respect superior to, but not inferior to, the prior art. A copolymer P containing mainly or exclusively acrylamide as an amino'=a sp54 form of acrylic acid is
Analogous is superior to the prior art due to its greater thermal stability. Copolymer P has very good performance for processing by injection molding; this also depends on the thermal conditions of injection molding, i.e. depending on the case. Crystallinity >260'O can be exposed without concern. ``The reduced thermal stability is demonstrated by the dynamic 1 (empty). Copolymer P contained as a containing derivative
In this case, the temperature TD at which double leaf loss is observed is generally clearly higher than in polymers containing dimethylaminoalkyl methacrylate as tracomonomer. Copolymers P containing mainly or exclusively acrylamide as the amine group-containing derivative of acrylic acid have particular compatibility as supports for wet metallization. This is all the more important since it has been demonstrated that the adhesion of wet-filtration deposited silver films to menal methacrylamide or vinyl methyl acetamide-containing supports is clearly inferior.
