2,4,6-Trisubstituted pyridines wherein at least one of the substituents is a para-(N,N-diarylamino)phenyl group, and the other two substituents are alkyl, cycloalkyl or aryl groups are useful as image dyes in acid-mediated imaging media, since the colored forms of these dyes display improved photostability as compared with similar trisubstituted pyridines which lack the para-(N,N-diarylamino)phenyl group. Salts of these trisubstituted pyridines are also useful in sensitizing 'onium salts to blue visible or similar radiation.

The following monohydroxy derivatives of 1-(1-phenylcyclohexyl)piperidine (phencyclidine, PCP) were synthesized: o-, m-, and p-phenols of PCP, 1-(1-phenylcyclohexyl)-4-piperidinol, and two stereoisomeric pairs of 3-phenyl-3-(1-piperidinyl)cyclohexanol and 4-phenyl-4-(1-piperidinyl)cyclohexanol.
