PURPOSE:To remove bleeding and fading of a coloring image by a method wherein a porous inorganic particle containing layer which has a specific oil- absorbed amount value and does not have colordeveloping capacity in reaction with an electron donative color former, is provided between a support and a color former layer. CONSTITUTION:A color former layer containing a micro-capsule containing an electron-donative color former is provided on one side of a support. A layer containing a porous inorganic particle which has at least 100ml/100g oil absorption amount and does not have color-developing capacity in reaction with an electron donative color former, is provided between the support and the color former layer to form a pressure sensitive recording sheet. Concretely an inorganic particle layer 22 is provided on one side of the support 21, and a color former layer 24 containing a micro-capsule 23 containing a developer is provided thereon to form a pressure sensitive recording sheet 20. When the pressure sensitive recording sheet is used for pressure printing by using an ink ribbon, neither bleeding nor fading of a coloring image occurs though stored for a long term. Therefore, it is especially useful for use of printing a bar code wherein accurate read is requested. |
