<p>A pressure sensitive recording sheet whose coated surface is in an even state is produced by a process employing a particular coating solution. The solution has a static surface tension of 42 dyne/cm or less and a surface tension increase of 5 dyne/cm or less, compared to its static surface tension, when its surface is extended, and further has a 50-mesh sieve passing fraction of 98% or more. A curtain coating process is used wherein the coating solution is applied to a surface of a continuously travelling support of great length in the form of a single-layer, freely falling curtain applied at a right angle to the support.</p> |
