ABSTRACT:
Paper and ink, each having a reactive component of a two part epoxy system, provide documents with print which is resistant to mechanical and chemical alteration. When the paper and ink are used in a printing process, the reactive components of the epoxy system form a thermoset polymer that fuses the ink to the paper. Money orders, checks, legal documents and transaction receipts resistant to alteration are provided.
