Beschreibung
Zusammenfassung:	The invention comprises compounds of the formula where Z is hyroxymethyl or a substituted aminomethyl group, R is aryl or substituted aryl, and R2, R3 and R4 are hyrogen or aliphatic or aromatic groups, which may be substituted; and their preparation by reacting a compound in which Z is hydrogen with formaldehyde or with formaldehyde and a secondary amine; solvents and heat may be used. In specified compounds, R is phenyl and (1) Z is morpholino-methyl; (2) Z is 1,2,3,4-tetrahydroquinolymethyl; (3) Z is piperidinomethyl; (4) Z is CH2OH; (5) Z is CH2OH and R2 is CH3; (6) Z is CH2OH and R2 is CH3 and R3 is CH2Cl; the other R radicals being hydrogen. Other values for Z, R, R2, R3 and R4 are specified. The compounds of the invention are photographic developing agents (see Division G2). Specifications 712,350, 725,573, 729,388, 729,862, 731,407, 731,419, 732,945, 757,271, 898,328 and 964,514 are referred to.
