  • Patent number: 7094454
    Abstract: A multi-color multi-ply note pad includes a plurality of note sheets, each of which has a perforated tear line that divides the note sheet into a stub portion and an inscribing portion, a binding member that binds the stub portions of the note sheets in a stack, and a repositionable adhesive layer provided on each of the note sheets at the inscribing portion of each of the note sheets and disposed adjacent to the tear line. The stub portions of the note sheets remain intact in the stack through the binding member when the inscribing portions of middle ones of the note sheets are removed from the stack.

  • Patent number: 6780486
    Abstract: A self-adhesive bulletin board assembly includes a bulletin board with a surface coated with a first adhesive layer that is adapted to be attached to a support surface, and a transparent sheet with opposite first and second surfaces that are coated with second and third adhesive layers, respectively. The transparent sheet is sandwiched between first and second protecting sheets prior to attachment of the same to the bulletin board, and is capable of visually exposing the bulletin board when removed from the first and second protecting sheets and attached to the bulletin board by one of the second and third adhesive layers.

  • Patent number: 6627285
    Abstract: A note pad includes a plurality of stacked self-stick transparent note sheets. Each of the note sheets includes a transparent plastic film coated with a transparent coating layer and a pressure-sensitive adhesive layer. The coating layer is prepared from a mixture of a binder and at least one pigment. The weight ratio of the binder to the pigment ranges from 1:1 to 1:10. Each of the note sheets has an opacity of less than 45%.

  • Patent number: 5863629
    Abstract: 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.
