Abstract

A thermally image record material such as a secure document is taught which is susceptible to rapid and bulk destruction of confidential or sensitive information by microwave or high energy absorption. The thermally responsive record material comprises a heat sensitive composition applied onto a substrate having provided thereon in proximity, to the heat sensitive composition as a subcoat or undercoat or back side coating, a layer of particles of an energy receiver material such as a microwave susceptor. Sensitive information imprinted on the record material can be readily destroyed by microwave heating.

Claims (9)

1. A method for obscuring confidential information comprising:

providing a substrate having first and second surfaces;

providing on the first surface one or more layers of a heat sensitive composition comprising a chromogenic material and an electron accepting developer material; providing on all or a portion of the second surface a layer of an energy receiver material; recording information onto the first surface by selectively thermally imaging the heat sensitive composition so as to record the information; and, colorizing the heat sensitive composition layer or layers in proximity to the energy receiver material by heating the energy receiver material by microwave absorption so as to obscure information recorded on the first surface.

2. A method for obscuring confidential information comprising:

providing a substrate having first and second surfaces;

providing on the first surface one or more layers of heat sensitive composition comprising a chromogenic material and an electron accepting developer material;

providing on all or a portion of the second surface a layer of an energy receiver material in proximity to the heat sensitive composition, applying the substrate as a label onto a pharmaceutical container;

recording information onto the first surface by selectively thermally imaging the heat sensitive composition so as to record information thereon;

colorizing the heat sensitive composition layer or layers in proximity to the energy receiver material by heating the energy receiver material by microwave absorption so as to obscure information recorded on the first surface.
