摘要：
Solid particle dispersions of blocked developers useful in imaging elements can be made with substantially improved stability to particle growth by dispersing the blocked developer of interest in the presence of a relatively small amount of an additional blocked developer that is structurally similar to the main blocked developer of interest. This additional blocked developer can be combined with the main blocked developer of interest prior to dispersing the main blocked developer of interest, i.e., prior to milling in the case of milled dispersions, and prior to precipitation in the case of pH or solvent precipitated dispersions.
