Appeal No. 2001-0731
Application No. 08/904,868
BACKGROUND
Appellants’ invention relates to a pressure sensitive cleaning article. The pressure
sensitive cleaning article comprises a substrate, a pressure sensitive adhesive layer and a
porous screen disposed on the pressure sensitive layer. Claims 1 and 7, which are
representative of the claimed invention, appear below:
1. A pressure-sensitive cleaning sheet comprising a substrate, a
pressure-sensitive adhesive layer formed on one or both sides of the substrate,
and a porous screen disposed on the pressure-sensitive adhesive layer, wherein
the cleaning sheet is substantially non-tacky when the cleaning sheet surface is
kept in a non-pressed state, under which the porous screen is projecting from
the surface of the pressure-sensitive adhesive layer;
the cleaning sheet exhibiting tackiness when the cleaning sheet is kept in a
pressed state, under which the pressure-sensitive adhesive layer appears on the
sheet surface through the openings of the porous screen; and
the cleaning sheet again becomes substantially non-tacky upon release from
pressing.
7. A roll-form image-forming material having a cleaning part, the cleaning
part comprising a pressure-sensitive adhesive layer having a porous screen
disposed thereon, wherein
the cleaning part is substantially non-tacky when the cleaning part surface is
kept in a non-pressed state, under which the porous screen is projecting from
the surface of the pressure-sensitive adhesive layer;
