Abstract
1521677 Pressure-sensitive copying material KORES HOLDING ZUG AG 21 June 1977 [23 June 1976] 25933/77 Heading D2B A pressure-sensitive copying material comprises a colour former embedded in a binder and an acid component capable of reacting with the colour former when brought into contact with it to form a colour image, said acid component being a chloride of a metal with an atomic weight of 50 to 66, which is in solid form and encapsulated in microcapsules.
