PURPOSE:To provide a pressure sensitive recording sheet wherein in the case where a large number of sets are piled upon each other and one side wall is pasted up, pasting is not generated among the sets each, by a method wherein a layer containing a surface active agent and water repellent agent at a specific ratio is provided on at least either one of the rear of a lower sheet or the surface of an upper sheet of the sets each through coating. CONSTITUTION:In a pressure sensitive recording sheet, a large number of sets which are constituted of an upper sheet and lower sheet or the upper sheet at least an intermediate sheet and the lower sheet and use color development reaction of an electron donating colorless coating with an electron accepting developer are piled upon each other and one side wall is pasted. Then a layer containing a surface active agent and water repellent agent so that a ratio of the surface active agent/repellent agent is 0.01-0.30 is provided through coating on at least one of the rear of the lower sheet or the upper sheet (excepting the upper most paper). With this construction, in the case where a large number of sets are piled up with each other and one side wall is coated with paste, pasting is not generated among the sets and the sets each can be stripped off reliaby and easily. |
