This invention relates to novel hindered cycloaliphatic monoisocyanates of the general formula: <IMAGE> wherein R1-R7 are members of the group consisting of H, alkyl, cycloalkyl, aryl, alkaryl, aralkyl or mixtures thereof wherein the alkyl groups contain 1-18 carbon atoms, the cycloalkyl groups contain 4-8 carbon atoms and the aryl groups contain 6-14 carbon atoms with the proviso that where R3 is a group member other than H, R1, R2, R4 and R5 can be H and with the further proviso that where R3 is H at least two of R1, R2, R4 and R5 are group members other than H and x is 1 to 7. Other novel dihindered intermediate compositions include aliphatic monoamines.
