ABSTRACT:
Disclosed herein are elements, including radiation-sensitive elements (e.g. color photographic paper products) which have, on a support, a substantially crystal- and agglomeration-free hydrophilic layer. This layer comprises a hydrophilic composition comprising a hydrophilic binder and water-insoluble polymer particles dispersed therein. These particles have recurring units derived from one or more ethylenically unsaturated polymerizable monomers, and comprise from about 0.5 to about 10 percent, based on total monomer weight, of a hydrophobe uniformly distributed throughout. Particularly useful polymer particles are those having recurring units derived from at least one monomer having a crosslinkable moiety. Particularly useful hydrophobes are optical brighteners. A method of making these elements is also disclosed herein.
