Abstract
In a support for a photographic printing paper, in which water-proof resin layers 2, 3 are formed on both sides of a base 1, one of the water-proof resin layers 2, 3, at a side of an emulsion to be coated, contains titanium dioxide pigment. The surface of particles of the titanium dioxide pigment is treated with a silane coupling agent. Preferably, the surface of titanium dioxide is subjected to surface treatment with an inorganic surface treating agent, and subsequently, is treated with the silane coupling agent. Further, silicone oligomer is preferably used as the silane coupling agent. As a result, a support for a photographic printing paper can be provided which causes no film fractures in the water-proof resin layers and no score lines in a die-lip portion, provides excellent adhesiveness to the base, and is superior in image sharpness.
