Abstract: An electrophotographic toner containing a compound of the following formula (I): ##STR1## wherein each of X and Y which are independent of each other, is a hydrogen atom, ##STR2## (wherein each of A.sub.1 and A.sub.2 is a hydrogen atom or an electron attracting group, provided that A.sub.1 and A.sub.2 are not simultaneously hydrogen atoms, R.sub.1 is a hydrogen atom, a halogen atom, an alkyl group, a cycloalkyl group, an aralkyl group, an aryl group, an alkoxy group, a dialkylamino group, a diarylamino group, a diaralkylamino group or a hydroxyl group, and n is 0, 1 or 2, provided that when n is 2, the plurality of R.sub.1 may be the same or different), ##STR3## (wherein A.sub.3 is an electron attracting group, and R.sub.1 and n are as defined above), ##STR4## (wherein A.sub.3, R.sub.1 and n are as defined above), ##STR5## (wherein A.sub.3, R.sub.1 and n are as defined above) or ##STR6## (wherein A.sub.3 is as defined above, and each of R.sub.2 and R.sub.

Abstract: Provided is a perfume composition containing a straight-chain trans-6-alkenoic acid represented by the general formula ##STR1## wherein n is an integer of 1 to 4.
