ABSTRACT:
Color-stabilized basic monomers are provided. Said basic monomers are (meth)acrylate or an N,N-dialkylaminoalkyl (meth)acrylamide!, at least one member selected from the group consisting of amido group-containing compounds, phosphorous acid esters, phosphoric acid esters and phosphines and at least one phenol compound represented by the general formula: ##STR1## wherein R.sup.5, R.sup.6, R.sup.8 and R.sup.9 are each independently a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; and R.sup.7 is a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or an alkoxy group having 1 to 4 carbon atoms. The color-stabilized basic monomers are more resistant to coloration when they are handled under such conditions that the oxygen concentration in the gas phase contacting therewith is 0.01 to 10% by volume.
