<P>PROBLEM TO BE SOLVED: To provide a recording paper for removable press bonding postcard having offset printability and ink-jet print aptitude and at the same time possessing good adhesion quality and removability which are deemed practically necessary as a confidential postcard paper, and especially to establish an extremely improved technique in concealment quality of printing and printed information. <P>SOLUTION: The recording paper for removable press bonding postcard having high concealment quality has, on both surfaces or on one side of a support, a pressure-sensitive adhesive layer which does not show adhesive property under normal condition, but shows adhesive property when pressurized, and is removable after bonding. The support is formed of a multilayered base paper using pulp fiber as its main element and consists of three or more layers of a surface layer, a rear layer and a middle layer with more than one layers in-between the surface layer and the rear layer. At least one or more layers of the middle layer are the colored shielding layers, and the pressure-sensitive adhesive layer contains amorphous synthetic silica and natural rubber based pressure-sensitive adhesive agent. <P>COPYRIGHT: (C)2011,JPO&INPIT |
