摘要: Compounds corresponding to formula (I): ##STR1## in which R.sub.1 represents alkyl, alkenyl, cycloalkyl or cycloalkenyl,R.sub.2 and R.sub.3 independently of one another represent H, alkyl, alkenyl, cycloalkyl or cycloalkenyl,R.sub.4 represents alkylene or alkenylene,X represents CO or SO.sub.2,m 0 or 1 andl is a number of 1 to 5,as coupler solvents lead to steeper gradation and greater maximum densities.
