<p><P>PROBLEM TO BE SOLVED: To enable to employ a thinner paper base material 1 which cannot be used for a conventional sticky note and to make the function of this sticky note paper be utilized for various products. <P>SOLUTION: A sheet material (base paper) 1 is so made by forming a color former layer 7 on an under surface 4 of a thin paper base material 1 and by forming a color developer layer 8 corresponding to the color former layer 7 on an upper surface 3. A middle paper 20 is so constructed by forming a weak adhesive agent layer 12 through a permeation preventing agent layer 11 on the under surface 4 of one end part 2 of the sheet material 1 and by forming a release processing layer 15 on the upper surface 3 of one end part 2. A lower paper 40 is so made by omitting the permeation preventing agent layer 11 and the weak adhesive agent layer 12 on the under surface 4 from the middle paper 20. An upper paper 30 is so made by omitting a release processing layer 15 on the upper surface 3 from the middle paper 20. In a standard type, the sticky note 50 is constructed by laminating one sheet of the upper paper 30 on the top most surface of and laminating one sheet of the lower paper 40 on the undermost surface of the laminated structure of the many middle papers 20, 20. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
