Compounds useful as a stabilizer for a variety of organic materials of an intermediate thereof, or as an intermediate of medicines or agricultural chemicals are disclosed, which are cyclohexylamine derivatives represented by the general formula [I]: ##STR1## wherein R.sup.1 represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an acyl group having 2 to 7 carbon atoms or an arylalkyl group having 7 to 10 carbon atoms; R.sup.2 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R.sup.3 and R.sup.4 both represent a hydrogen atom, or one of R.sup.3 and R.sup.4 represents a hydrogen atom and the other represents a group --CH.sub.2 --R.sup.5, or R.sup.3 and R.sup.4 together form a group .dbd.CH--R.sup.5, in which R.sup.5 represents an unsubstituted or C.sub.1 -C.sub.4 alkyl substituted phenyl group, a 2-furyl group, a cyclohexyl group or a 2-tetrahydrofuryl group; X represents an alkylene group having 1 to 3 carbon atoms; and n denotes 1 or 2. When the compound is used as a stabilizer, it exhibits little bleedout and high photostabilizing effect.
A cyclohexylamine compound represented by the general formula:
N,N-bis[2-(1,2,2,6,6-pentamethyl-4-piper idinyloxy-carbonyl)ethyl]cyclohexylamine.
N-[2-(1,2,2,6,6-pentamethyl-4-piperid inyloxycarbonyl)ethyl]dicyclohexylamine.
N-[2-(3-benzyl-2,2,6,6-tetramethyl-4 -piperidinyloxycarbonyl)ethyl]dicyclohexylamine.
N-[2-(3-cyclohexylmethyl-2,2,6,6-tetramethyl -4-piperidinyloxycarbonyl)ethyl]dicyclohexylamine.
