The present invention relates to cure accelerators useful for anaerobic curable compositions, such as adhesives and sealants. The cure accelerators may be embraced generally within the structure below

##STR00001##

where X is CH.sub.2, O, S, NR′, CR″R′″ or C═O; R is hydrogen or (meth)acryl; R.sup.6 is hydrogen, halogen, amino, carboxyl, nitro, alkyl, alkenyl, alkynyl, hydroxyalkyl, hydroxyalkenyl, hydroxyalkynyl, or alkaryl; and A and A.sup.1 are each individually selected from hydrogen or taken together create a ring structure of 5 to 12 total ring atoms, wherein the ring structure may be cycloaliphatic, cycloheteroaliphatic or aromatic or combinations thereof with or without substitution by one or more hydroxyl or (meth)acryl groups; and n is 0 or 1, provided that when R is hydrogen, A and A′ cannot both be hydrogen or taken together cannot be naphthyl.

The invention relates to the identification of polymer materials on the basis of the fluorescence decay time of the intrinsic fluorescence of the polymer materials for definite sorting in a completely separated manner. The invention further relates to marking with fluorescent dyes, which, because of the specific fluorescence decay times of the fluorescent dyes, can further increase the sorting reliability by means of redundancy and can be used to identify particular batches.
