Abstract
A pressure sensitive carbonless copying system includes a first sheet having front and back surfaces, the back surface coated at least in part with a composition including a mixture having a pressure sensitive adhesive component and a carbonless microcapsule component; and a second sheet having front and back surfaces, the front surface coated with a carbonless image transfer material, and wherein the first sheet is temporarily adhered to the second sheet by means of the pressure sensitive adhesive component of the mixture.
Claims12
A pressure sensitive carbonless copying system comprising:
- a) a first sheet having front and back surfaces, said back surface coated at least in part with a composition including a mixture having a pressure sensitive adhesive component and a carbonless coating component including microcapsules containing a colorless dye;
- and
- b) a second sheet having front and back surfaces, said front surface coated with a carbonless image transfer material for cooperation with said carbonless coating component to enable an image to be transferred to said second sheet upon application of localized pressure to said first sheet and wherein said first sheet is temporarily adhered to said second sheet by means of said pressure sensitive adhesive component of said mixture.
A pad comprising a plurality of note sheets, each note sheet having an upper surface and a lower surface, wherein at least a portion of the lower surface of each sheet is coated with a composition including a mixture having a pressure sensitive adhesive component and a carbonless component including microcapsules containing a colorless dye;
- and wherein the upper surface of each sheet is at least partially coated with a carbonless image transfer material for cooperation with said carbonless coating component to enable an image to be transferred to said second sheet upon application of localized pressure to said first sheet.
