Patent

CA 2122693

A business record such as a form, tag, label or the like is provided in which different selected colored areas may be activated in a single pass through a printer. In one embodiment, coatings of initially colorless color formers and color developers are coated on selected areas of a substrate surface. The color formers and color developers combine upon exposure to an imaging force, such as heat or pressure, to form different colored visible areas on the sheet. In an alternative embodiment, the coatings of color formers and color developers are self-contained coatings having pressure-rupturable microcapsules containing either the color formers or said color developers.

L'invention porte sur un document professionnel, tel qu'un formulaire, une étiquette ou un autre document semblable, sur lequel des zones de couleurs peuvent être activées par un seul passage dans l'imprimante. Dans un modèle, des couches de substances et de révélateurs chromogènes initialement sans couleur sont déposées sur des zones sélectionnées de la surface d'un subjectile. Les substances et les révélateurs chromogènes se combinent lorsqu'ils sont exposés à une force d'imagerie, telle que la chaleur ou la pression, pour créer différentes zones colorées sur la feuille. Dans un autre modèle, les couches de substances et de révélateurs chromogènes sont des couches autonomes comprenant des microcapsules qui éclatent à la pression et qui contiennent soit des substances chromogènes, soit des révélateurs chromogènes.
