Abstract
1335730 Pyrazoline compounds KONISHIROKU PHOTO INDUSTRY CO Ltd 17 Dec 1971 [18 Dec 1970] 58644/71 Heading C2C [Also in Division G2] Novel pyrazoline compounds having two heterocyclic rings, believed to be of the formula may be obtained by reacting with formaldehyde in acetic acid a compound of the formula I or II wherein R represents an aryloxyalkyl or alkyl group, the aromatic nucleus of the aryloxyalkyl group being optionally substituted, and n is 0 or 1, R<SP>1</SP> represents a hydrogen atom or an alkyl group, X represents a halogen atom and each of Y and Z independently represents a hydrogen atom, halogen atom or C 1-4 alkyl or C 1-4 alkoxy. The novel compounds are useful as colour couplers.
