摘要：
A silver halide photographic printing paper is described, comprising a support and a photographic layer containing a silver halide developing agent, wherein a dispersion of an oil-soluble brightening agent in a high boiling point organic solvent having a specific inductive capacity of 7.5 or less is contained in the photographic layer. This printing paper yields a background of high whiteness even when processed under rapid processing conditions.
