ABSTRACT:
A photographic support comprises a paper coated on both sides with polyethylene resin film. For providing improved cutting property of the paper when it is used for a photographic paper and subjected to an automatic printer/cutter, strength reinforcing and sizing agents contained in the support are made such that amount ratio of the former to the latter is at least 1.8. To impart the paper a desirable stiffness and further improved cutting property, polyvinyl alcohol fibers which are neither heat-treated nor acetalized, in 5-25 parts by weight, are mixed to 100 parts by weight of woodpulp fibers when the paper is formed. This allows to make the paper as light as 160 g/m.sup.2 or less but having stiffness property pertaining to photographic papers.
