A carbonless copy note pad includes a stack of note sheet sets. Each of note sheet sets includes first and second paper sheets, first and second adhesive layers, a color-developing coating layer, and a coarse particle coating layer. The color-developing coating layer is formed on at least one of the first and second paper sheets. The coarse particle coating layer is formed on a lower surface of the second paper sheet, and has a roughened surface to prevent a scribbling pressure applied to a writing surface of the first paper sheet of a topmost one of the note sheet sets from affecting a next one of the note sheet sets.

Carbonless copy note pad

The copying system comprises a plurality of units in a stacked configuration, where each unit comprises two or several sheets of carbonless, repositionable self-adhesive paper. Image transfer upon writing pressure results in copies of the message made in a single unit but not on subsequent units in the stack. Image transfer is controlled by regulating the microcapsule size of the carbonless copying component on the first sheet in each unit and the basis weight of the last sheet of paper in each unit.

Writing system of stacked carbonless repositionable self-adhesive paper

This invention pertains to a carbonless copying system for making multiple copies of a message, comprising a plurality of carbonless paper sheets of which each sheet of carbonless paper comprises a region of removable, repositionable pressure sensitive adhesive on the back surface of the sheet. The method for manufacturing the removable and repositionable pressure sensitive carbonless copying system and their use for making multiple copies of a message are also described.
