A composition based on extract from cacti is used as an insecticide against soft bodied insects injurious to plants. A process for preparing the extract and its use as an insecticide are given.

Disclosed are novel organic pigments adapted particularly for use as fillers for paper. The organic pigments are finely divided particles obtained by graft copolymerizing an ethylenically unsaturated monomer, such as styrene, onto a water-soluble cationic prepolymer in an aqueous solution and in the presence of a free-radical polymerization initiator.

The invention relates to an antiserum suitable for the determination of thioridazine in blood, blood plasma and urine, the use of the antiserum and a process of determining thioridazine in blood, blood plasma or urine with the aid of this specific antiserum.

An organic photoconductor including a base layer formed of a first material and a photoconductive layer formed of a second material. The organic photoconductor being characterized in that when it is maintained in a curved orientation with the photoconductive layer facing outward, the photoconductive layer is subjected to less stress than the base layer. In one embodiment the first material is relatively more flexible and stretchable than said second material and the materials are pre-stressed in...
