The present invention also relates to a silver halide photographic material having stability over time, which is obtained by dispersing a hydrophobic photographic additive using at least two types of nonionic surfactants.

いられる。[Background of the Invention] Generally, a photographic light-sensitive material has a plurality of photographic constituent layers containing hydrophilic colloids provided on a photographic support. These photographic constituent layers have various functions such as an undercoat layer, an intermediate layer, a photosensitive layer, a surface protective layer, etc., and in order to satisfy these functions, each layer has various functions such as couplers, ultraviolet absorbers, Contains hydrophobic photographic additives such as optical brighteners. When applying a hydrophilic colloid liquid containing an organic solvent for the additive or a hydrophobic synthetic polymer such as an acrylic acid ester as a dispersion, a surfactant is often used as a dispersant.

すことは容易なことではない。However, surfactants used in photographic materials have good photographic properties such as photographic sensitivity, fog, gradation, and speed of development, as well as good processing properties (i.e., necessary for rapid processing).
It is necessary that the photographic properties of a photographic light-sensitive material are not affected by a trace amount of substances added to the photographic emulsion. It is often difficult to find a compound that fully satisfies the purpose of dispersion and has no adverse photographic effect even in the case of surfactants.

に対して不充分でありながらも、仕方なくアニオン性界
面活性剤を使用しているというのが現状であった。For the purpose of coating and dispersing photographic materials, anionic surfactants are generally used as surfactants, and nonionic surfactants have not been used at all. The reasons for this are: firstly, photographic dispersions using only nonionic surfactants have insufficient dispersing ability and cannot obtain uniform dispersions, and secondly, photographic dispersions containing only nonionic surfactants When a silver halide photographic light-sensitive material is developed, the development speed is not as desired, and there are drawbacks that have a large impact.9 For example, depending on the type of photographic light-sensitive material, the development speed may become too slow or , or the development speed is too fast, making it impossible to obtain good photographic images. Therefore, the current situation is that anionic surfactants have no choice but to be used, even though they are insufficient for photographic properties.

It has been discovered that the method has excellent effects in terms of stability over time and photographic properties.

インダーとして用いられるものがすべて用いられる。Next, a typical method for dispersing a hydrophobic photographic additive into a hydrophilic colloid binder using the dispersant of the present invention will be described. To disperse a hydrophobic photographic additive in a hydrophilic colloid binder, the hydrophobic photographic additive is first dissolved in a low boiling organic solvent such as ethyl acetate, methanol, ethanol, or the like. At this time, a high boiling point organic solvent such as dibutyl phthalate, tricresyl phosphate, dinonylphenol, diethyl laurylamide, diethylene glycol butyl acetate, etc. can be added to promote dissolution of the hydrophobic photographic additive. To disperse the hydrophobic photographic additive thus dissolved into the hydrophilic colloid binder, the surfactant of the present invention is used in a conventional manner, for example, using a mixer, homogenizer, etc.
It is dispersed into a woody colloid using a colloid mill or an ultrasonic dispersion machine. As the wood-philic colloid, all those commonly used as binders for photography can be used.
