ABSTRACT:
A process of making polymeric matte bead particles for use in photographic elements which comprises forming a suspension of ethylenically unsaturated monomer droplets in an aqueous media, subsequent to the formation of droplets and before commencement of reaction, adding to the aqueous media an effective amount of a hydrophilic colloid to improve adhesion and polymerizing the monomer to form solid polymeric particles.
