ABSTRACT OF THE DISCLOSURE A self-contained carbonless coating composition which can be printed onto one or more sheets of a business form or mailer to provide the capability for producing a visible image which is more intense (i.e.,darker) and sharper than previous coatings is provided. The composition also finds use on security documents to provide a covert image on the document beneath information which may be subject to attempted alteration, such as an amount written on a check. The covert image becomes visible upon the application of pressure in the area coated to provide evidence of the attempted alteration. The self-contained composition includes a dispersed color former and a plurality of pressure-rupturable microcapsules containing a color developer.
