Photographic element for color diffusion transfer process

A photographic element for color diffusion transfer process comprising a support and thereon, as essential layers, a neutralizing layer and a timing layer in this order, wherein said timing layer comprises a polymeric latex represented by the general formula [I];

• --A--.sub.x --B--.sub.y --C--.sub.z [I]
• wherein A represents a copolymerizable conjugated diene monomer unit, B represents a copolymerizable ethylenically unsaturated acid monomer unit or a salt thereof, C represents a copolymerizable ethylenically unsaturated monomer unit, x, y and z individually represent a portion contained in said polymeric latex in terms of percentage by weight, and x is from about 55 to about 99.5%, y is from about 0.5 to about 44.5%, and z is from zero to about 44.5%.
