ABSTRACT:
A method for monitoring a property of a cationically curable composition comprising the steps of: adding a fluorescence probe to a cationically curable composition; measuring the intensity of the fluorescence emission of the probe at a wavelength at which intensity changes in response to changes occurring in the composition, wherein the fluorescence probe is a compound of the formula (I): ##STR1## where R.sup.1, R.sup.2 and R.sup.3 are the same or different and represent hydrogen, C.sub.1 -C.sub.20 alkyl, C.sub.1 -C.sub.20 alkoxyl, C.sub.2 -C.sub.20 alkenyl, C.sub.2 -C.sub.20 alkenoxyl, C.sub.3 -C.sub.27 cycloaliphatic, C.sub.7 -C.sub.27 aralkyl, C.sub.7 -C.sub.27 aralkoxyl, C.sub.7 -C.sub.27 alkaryl, or a substituted or unsubstituted diphenyl ether having the structure R.sup.9 --C.sub.6 H.sub.4 --O--C.sub.6 H.sub.4 R.sup.10 where R.sup.9 and R.sup.10 may be hydrogen, alkyl, aryl or aralkyl; and R.sup.1,R.sup.2 and R.sup.3 may be unsubstituted or may be substituted with or contain therein one or more atoms selected from the group consisting of O, S, N, OH, SH, NH.sub.2, P, Cl, Br and I; and R.sup.4 may be the same as R.sup.1, R.sup.2 and R.sup.3 ; or R.sup.4 may represent COOR.sup.5, CONR.sup.5 R.sup.6, SO.sub.2 OR.sup.5, SOOR.sup.5, SONR.sup.5 R.sup.6, SO.sub.2 NR.sup.5 R.sup.6 or NR.sup.5 R.sup.6, where R.sup.5 and R.sup.6 may be hydrogen, alkyl, aryl or aralkyl; curing the composition; causing the probe to fluoresce; measuring the fluorescence of the probe; relating the change in intensity to a monitored property of the composition; and determining the monitored property of the composition, based upon the change in intensity.
