Abstract
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.
