A photographic film which comprises (A) a support, having two sides, (B) at least one light-sensitive emulsion layer on one side of said support (A), and, (C) at least one layer containing a compound represented by formula [I]and a hydrophobic polymer (first layer) and at least one layer containing an antistatic agent (second layer), said first and second layers being placed on the other side of said support (A) and said first layer being placed closer to said support (A) than said second layer: ##STR1## wherein, R.sub.1 represents a carboxylic acid residue having from 12 to 24 carbon atoms and R.sub.2, R.sub.3 and R.sub.4 represent independently hydrogen atoms or organic acid residues having from 1 to 24 carbon atoms.

Photographic films

A process for the preparation of a silver halide photographic material is disclosed which provides for the formation of a photographic layer by the use of a coating solution containing a compound represented by formula I or II.

Process for the preparation of light-sensitive silver halide

An antistatic light-sensitive silver halide photographic element having an addition copolymer of glycidol and ethylene oxide with a phenol-aldehyde condensate as the antistatic agent, is described.

Antistatic light-sensitive silver halide photographic element

A photographic light-sensitive material comprising a layer which contains a compound represented by the following Formula I ##STR1## wherein R.sub.1 is an alkyl group having 1 to 18 carbon atoms, R.sub.2 is a hydrogen atom or an alkyl group having 1 to 18 carbon atoms with a proviso that when R.sub.2 is a hydrogen atom, R.sub.1 is an alkyl group having 1 to 7 carbon atoms, M is a cation and n is a number of 1 to 50.

Photographic light-sensitive material

A color diffusion transfer photographic unit is disclosed which contains a silver halide photosensitive element having a support and at least one silver halide emulsion layer thereon and an image receiving element having a support and an image receiving layer thereon wherein the unit contains a polymer having a first monomer which contains a tertiary nitrogen atom wherein at least 5 mole % of said first monomer is grafted and/or graft-copolymerized with a second monomer which is a vinyl monomer having a tertiary or quaternary nitrogen.

Color diffusion transfer unit with polymeric quaternary nitrogen mordant
