Abstract

Anaerobically hardening adhesive compositions principally composed of a polymerizable acrylic ester and an organic aerobically-inactive, anaerobically-active peroxide polymerization catalyst therefor possess improved latent adhesive properties for metals when they contain an acrylic ester-acid of the formula: ##STR1## wherein R is --H or --CH.sub.3 ; R' is H, halogen, --COOH, --CN, and loweralkyl, and X is a divalent C.sub.1-6 hydrocarbon group, or a mixture of such ester-acids.
