发明名称 Coloring stabilized bleach activator extrudates.
摘要 <p>This invention relates to a process for applying water-soluble dye or water-dispersible pigment to stabilized bleach activator extrudates in a manner which avoids agglomeration and allows even coating of the bleach activator extrudates. This is accomplished by adding water-soluble hydratable material and the dye or pigment to an aqueous solution, and then distributing the aqueous solution on the bleach activator extrudates. The bleach activator extrudates comprise specific peroxygen bleach activators and select binder materials. This invention also relates to colored bleach activator extrudates made according to this process.</p>
