Estimating the term…
A pressure-sensitive cleaning sheet is disclosed which comprises 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. The cleaning sheet is substantially non-tacky when the cleaning sheet surface is kept in a non-pressed state, and exhibits tackiness when the cleaning sheet surface is kept in a pressed state. Also disclosed are a method of using the cleaning sheet, an image-forming material having a cleaning part, and a method of cleaning an image-forming apparatus. These are useful for the cleaning of, e.g., the magnetic reading parts and magnetic-card transport parts of apparatuses accepting various magnetic cards and the thermal heads and/or transport rollers of various recording apparatuses.
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
A method of using 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, the cleaning sheet being 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, and the cleaning sheet exhibiting tackiness when the cleaning sheet surface 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 to thereby have a surface which is on almost the same level as the surface of the porous screen and the cleaning sheet again becomes substantially non-tacky upon release from pressing,
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
A method of cleaning an image-forming apparatus which comprises cleaning a thermal head and/or a transport roller of the apparatus by transporting through the apparatus a roll-form image-forming material having a cleaning part comprising a pressure-sensitive adhesive layer having a porous screen disposed thereon,
