Abstract
A security composition for use with an ink composition including diphenyl guanidine and acrylic resin. The ink composition may further include a glycol ether and a plasticizer and can be printed on paper, for example in the word 'VOID'. If bleach is used to attempt to alter the document, the initially colorless ink will form a colored image in the shapes or letters printed on the paper. The ink composition is resistant to leaching upon contact with, for example, water.
