Acrylic Gesso works well.
Acrylic Gesso a mixture of a PVA type of substrate with a chalk like substance. It adheres well to the soft plastic, and gives a good key for painting.
You can buy it from graphics art shops. It can be slightly diluted with water, and if you like it can be coloured with acrylic paint, to give you a quick start on the final paint job.
You need to make sure the figures are completely clean and grease free before priming. Do this by scrubbing lightly in warm water and detergent, then rinsing and drying.
