- the electrophotographic image receiving papers of Comparative Example 5 and Comparative Example 6 were remarkably inferior in fixability because the Tg of the resin used in the toner receiving layer was too low or too high.
- the electrophotographic image-receiving paper of Comparative Example 7 had a low resistance treatment agent in the toner-receiving layer, so that capri was generated and transferability was remarkably inferior.
- the electrophotographic image-receiving paper having water resistance of the present invention is excellent in water resistance, antifouling property, fixing property and transferability, and does not generate blisters during heat fixing, or does not generate sticking during continuous printing.
