A thermally imagable business record, such as a form, label, tag, or the like is provided which may be activated to form human and/or machine readable images as well as different colored images. The record comprises a substrate having a thermally imagable coating on substantially its entire surface which forms a first color when activated, and having a desensitized area on at least one area of its surface which may be overcoated with a thermally imagable coating capable of forming a different color upon activation than the first thermally imagable coating. The first thermally imagable coating provides images which are of machine readable quality, while the additional thermally imagable coatings provide images of a different color to designate selected areas on the form or label to a user.

A direct thermal ink composition is provided which is formed from an aqueous dispersion of an initially colorless color former and an initially colorless color developer in particulate form. The direct thermal ink composition also includes a sensitizer, where the particles of the sensitizer at least partially surround the particles of the color developer, which prevents premature color development of the ink. The thermal ink preferably has a solids content of between about 40 to 60% by weight, and is substantially free of pigments and fillers.
