A process for forming photographic images comprising a silver image and a dye image, comprising development processing an imagewise exposed silver halide photographic light-sensitive material containing a 4-alkoxy-1-naphthol represented by the formula (I) ##STR1## wherein R represents an alkyl group, an alkoxyalkyl group, or a hydroxyalkyl group, and the number of carbon atoms in the substituent represented by R is from 1 to 4. The process of this invention is particularly useful in the field of X-ray photography, in order to provide an image of increased density for a given silver content. A novel silver halide photographic light-sensitive material includes the above 4-alkoxy-1-naphthol in a photographic colloid layer thereof, preferably the silver halide emulsion layer.
In a process for forming a photographic image comprising a silver image of improved granularity and a dye image, comprising development processing an imagewise-exposed silver halide photographic light-sensitive material, the improvement wherein said development processing is carried out in the presence of a 4-alkoxy-1-naphthol represented by the formula (I) ##STR12## wherein R represents an alkyl group, an alkoxyalkyl group, or a hydroxyalkyl group, and the number of carbon atoms in the substituent represented by R is from 1 to 4, which is incorporated into said silver halide photographic light-sensitive material.
In an image-wise exposed and developed silver halide photographic light-sensitive material comprising a support having coated thereon one or more hydrophilic layer(s), the improvement wherein the image resulting from said development has improved granularity and comprises both a dye and silver and wherein at least one of said layer(s) prior to development contains a 4-alkoxy-1-naphthol represented by the formula (I) ##STR14## wherein R represents an alkyl group, an alkoxy-alkoxy group, or a hydroxyalkul group, and the number of carbon atoms in the substituent represented by R is from 1 to 4.
