Abstract (en)

[origin: WO8706723A2] Imaging elements, including radiation-sensitive elements such as photographic color paper products, are comprised of a support bearing a substantially crystal- and agglomeration-free hydrophilic layer. This layer comprises a hydrophilic composition containing a hydrophilic binder and water-insoluble polymer particles dispersed therein. These particles have recurring units derived from a monomeric composition composed of one or more ethylenically unsaturated polymerizable monomers with more than about 5 percent and up to 100 percent by weight of the monomeric composition consisting of at least one ethylenically unsaturated polymerizable monomer having a crosslinkable moiety, and comprise at least about 0.5 percent by weight of a hydrophobe uniformly distributed throughout.
