Patent number: 4214047Abstract: This invention is directed to photographic elements having hydrophilic colloid layers containing loaded particles of from 0.02 to 0.2 micron in average diameter consisting essentially of a loadable polymer, with greater than 2 percent by weight of the polymer being derived from monomers capable of forming water soluble homopolymers. A hydrophobic photographic dye, coupler, developing agent or ultraviolet absorbing compound is loaded into and distributed through the particles. The weight ratio of the hydrophobic photographic dye, coupler, developing agent or ultraviolet absorbing compound to the loadable polymer is from about 1:4 to 3:1.Type: GrantFiled: May 4, 1979Date of Patent: July 22, 1980Assignee: Eastman Kodak CompanyInventor: Tsang J. Chen

Patent number: 4207109Abstract: Copolymers containing an acrylamidophenol as a crosslinking site and the corresponding crosslinked polymers are disclosed. The acrylamidophenol unit can be copolymerized with a wide variety of other monomers to provide crosslinkable and crosslinked polymers with useful properties. The acrylamidophenol unit provides for crosslinking at low pH with conventional crosslinking agents. The acrylamidophenol monomer unit is present in the copolymer from about 0.5 to 50 percent by weight and has the formula: ##STR1## wherein: x is 1 or 0,L is a linking group,R represents hydrogen or methyl, andR.sup.1 through R.sup.5 are independently selected from the group consisting of hydrogen, hydroxy, alkyl from 1 to 6 carbon atoms and aryl from 6 to 10 carbon atoms; with the proviso that at least one of R.sup.1 through R.sup.5 is hydroxy and at least one of the positions ortho or para to said hydroxy has a hydrogen atom attached thereto. The remainder of the polymer can comprise from 50 to 99.Type: GrantFiled: April 5, 1978Date of Patent: June 10, 1980Assignee: Eastman Kodak CompanyInventors: Gerald A. Campbell, Kenneth R. Hollister, Richard C. Sutton
