Memorandum block of a stack of paper sheets, has sheet areas divided by perforations into two size formats with an adhesive in a particular zone to be activated by pressure to stick the paper to a surface

摘要

The memorandum pad is a block (1) of paper sheets, where each sheet carries an adhesive which gives an adhesion or an increased adhesion when pressure is applied to the treated zone. The memorandum sheets in the stack are perforated (2) to give two sizes (A,B) which can be used separately, or the whole sheet as a third option. Each sheet is treated with two types of adhesive, of different adhesion strengths, on separate surface areas. The second adhesive is contained within micro-capsules to be released by pressure.
