ABSTRACT:
A method for producing a pressure-sensitive copying sheet which comprises winding the pressure-sensitive copying sheet having a microcapsule coating film comprising microcapsules having an average particle size of 3-8 microns and a hydrophobic oil containing 3-6% by weight of a color former at 35 kg/m or less, and while winding continuously reducing the winding tension to an amount of about 40 to 70% of the initial winding tension as the roll diameter increases. An embodiment is also disclosed where said coating contains an antismudging and/or a covering agent and the initial winding tension is 70 kg/m or less.
