Claims
- 1. A method for metallizing at least a portion of the surface of an article, at least the surface portion of the article to be metallized being a polymer consisting essentially of 50 to 99 percent by weight of an ester of acrylic acid or of methacrylic acid with an alcohol having 1 to 20 carbon atoms, from 0 to 49 percent by weight of at least one member selected from the group consisting of styrene, alpha-methyl styrene, para-methyl styrene, acrylonitrile, or methacrylonitrile, and from 1 to 15 percent by weight of a member selected from the group consisting of acrylamide and dimethylaminoethyl methacrylate, which method comprises contacting said surface to be metallized with an hydroxy-substituted aromatic acid and then wet metallizing the acid-treated surface.
- 2. A method as in claim 1 wherein said acrylamide or dimethylaminoethyl methacrylate is present in an amount of 7.+-.5 percent by weight.
- 3. A method as in claim 1 wherein said polymer is an acrylic polymer having a glass transition temperature, Tg, above 70.degree. C.
- 4. A method as in claim 1 wherein said polymer comprises from 50 to 99 percent of methyl methacrylate.
- 5. A method as in claim 1 wherein said polymer additionally comprises from 1 to 30 percent of methyl acrylate.
- 6. A method as in claim 1 wherein after said acid treatment and prior to wet metallization, said surface to be metallized is sensitized with a solution of a salt of a reducing metal.
