Abstract
Disclosed is a method for printing onto pressure-sensitive record material of the kind comprising a base sheet, typically of paper, coated with a ruptutrable material confining droplets of color forming substances in a solutuion of animal or vegetable oil solvent, which when released by rupture of the material undergo a color forming reaction to produce an image either on the base sheet itself or on a further receptor sheet in face-to-face contact with the coated face of the base sheet.
