Patent number: 5256527Abstract: The invention provides stable dispersions of couplers and methods of their formation. The stable dispersions are formed by the use of a nonionic water soluble polymer in combination with an anionic surfactant having a sulfate or sulfonate head group and a hydrophobic group of 8 to 20 carbons. The preferred nonionic water soluble polymers are polyethyleneoxide and polyvinylpyrrolidene. It is preferred that the dispersions have a pH of between about 5 and 5.5.Type: GrantFiled: September 9, 1991Date of Patent: October 26, 1993Assignee: Eastman Kodak CompanyInventors: Krishnan Chari, James T. Beck

Patent number: 5158863Abstract: The invention is performed by providing a first flow of water and surfactant, a second flow comprising solvent, base and photographic material, and mixing said first and second streams and either simultaneously or immediately following thereof neutralizing said streams to prevent hydrolysis of a hydrolyzable surfactant and/or premature precipitation of particles before neutralization. The streams then may be immediately treated for formation into photographic materials. In a preferred method the first and second stream may be brought together immediately prior to a mixer with addition of acid directly into the mixer to neutralize the dispersion of fine particles.Type: GrantFiled: February 1, 1991Date of Patent: October 27, 1992Assignee: Eastman Kodak CompanyInventors: Pranab Bagchi, James T.
