These acrylic and methacrylic compounds are chosen from those of the formula: <IMAGE> (I) <IMAGE> (II) <IMAGE> (III) in which R1 is H or CH3; A is (CH2)n or n is an integer from 2 to 12 or -(CH2CH2O)d-CH2CH2-, d is an integer from 1 to 20; X is S or O; Y is S or O, under the condition that X is S and Y is O when A is -(CH2CH2O)d-CH2CH2-; R is C1-C20alkyl or -(CH2)pSR3 where p is an integer from 3 to 12 and R3 is C1-C20-alkyl; m is an integer from 1 to 3; and Z is H, R2QH, or R2 is C2-C12-alkyl and Q is O or S, and the atoms of the metals from Groups IA, IIA, IIIA, IB, IIB, VIB, VIIB and VIII of the Periodic Table, on condition that Z is H or R2OH when m is 1 and m is the valence of Z when Z is a metal.
