Support for image recording material
A support for image recording material containing a base paper, both surfaces of which are coated with a polyolefin resin and/or a polyester resin, wherein the base paper contains kraft pulp made from acacia as a component thereof. The base paper preferably contains an anionic polyacrylamide in an amount of 0.05 to 1.5% by mass and an epoxidized fatty acid amide in an amount of 0.05 to 0.8% by mass.

19 . A method for manufacturing a support for a photographic printing paper which is used for a photographic material to be processed by a wet process, the method comprising: calendaring a base paper at a temperature in a range of 50 to 250° C. under a pressure in a range of 50 to 300 kg/cm, and coating both surfaces of the base paper with at least one of a polyolefin resin and a polyester resin, wherein the base paper contains kraft pulp made from acacia, an anionic polyacrylamide in an amount of 0.05 to 1.5% by mass and an epoxidized fatty acid amide in an amount of 0.05 to 0.8% by mass, as components thereof.
20 . A method for manufacturing a support for a photographic printing paper according to claim 19 , further comprising subjecting the base paper to a corona discharge treatment, a flame treatment, a glow discharge treatment or a plasma treatment before the base paper is coated with the polyolefin resin.
21 . A method for manufacturing a support for a photographic printing paper according to claim 20 , wherein pulp constituting the base paper contains the pulp made from acacia in an amount of 25 to 100% by mass.
22 . A method for manufacturing a support for a photographic printing paper according to claim 20 , wherein the kraft pulp made from acacia is beaten so that a water retention value thereof is in a range of 150 to 180%.
23 . A method for manufacturing a support for a photographic printing paper according to claim 20 , wherein in the support, a layer made of the polyolefin resin and having a thickness in a range of 15 to 40 μm is provided on the base paper.
24 . A method for manufacturing a support for a photographic printing paper according to claim 20 , wherein on the support a back-coat layer is provided.
25 . A method for manufacturing a support for a photographic printing paper according to claim 20 , wherein the base paper contains an alkylketene dimer in an amount of 0.1 to 0.6% by mass.
26 . A method for manufacturing a support for a photographic printing paper according to claim 20 , wherein a molecular weight of the anionic polyacrylamide is in a range of 100,000 to 1,000,000.
27 . A method for manufacturing a support for a photographic printing paper according to claim 1 , wherein a raw material of the epoxidized fatty acid amide is behenic acid.
