A composition useful as an adhesion promoting primer activator for curable acrylic monomer formulations, particularly anaerobic curable formulations, comprises a solution in a volatile organic solvent of a Cu(II), Co(II), Mn(II), Mn(III), or Cr(III) salt of an acid phosphate acrylic monomer. The acid phosphate monomer may be one of the formula: <IMAGE> where R1 is H or methyl, R2 is a divalent organic group having 2-40 carbon atoms and A is OH or CH2=C(R1)C(=O)OR2O.
