BASE FOR PHOTOGRAPHIC PRINTING PAPER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a base for photographic printing paper having high rigidity and high smoothness by using base paper free of restoration to its rugged state even by heat particularly in melt coating of the base paper with a polyolefin resin and retaining high smoothness even after coating with the polyolefin resin. SOLUTION: In the base for photographic printing paper obtained by coating at least one face of base paper with a polyolefin resin, the one face of the base paper has been crosslinked with a chemical reaction crosslinking resin composition and calendered. Preferably the chemical reaction crosslinking resin composition is an aqueous solution and is applied or impregnated by a size press system and heat calendering is carried out with a heated metallic roll.
