Abstract
A polymer comprising acrylamide units or anionic sulfonate units and a unit having the formula: ##STR1## wherein: R is H, halogen or alkyl; L is a linking group; and M is H, an ammonium cation or an alkali metal, can be metallized to form a metallized polymer. The metallized polymer is useful either as or with a mordant for dyes or dye formers that chelate metals.
