PURPOSE:To efficiently obtain the subject paper without requirement of processes such as dyeing, drying or rebeating by breaking a waste paper having a water-resistant coating layer in water and making a paper using a pulp containing the above reproduced pulp. CONSTITUTION:A waste paper having a water-resistant coating layer is broken in water and the resultant reproduced pulp is blended in an amount of >=2wt.% based on the whole pulp composition. The mixed pulp is subjected to paper making, thus obtaining the objective paper. In addition, a heat-sensitive recording paper containing a colorless or light-colored basic dyestuff and a chromogenic agent is preferable as the above-mentioned waste paper. |
