ABSORBENT ARTICLES INCLUDING HIPE FOAM IMPARTED WITH COLOR, AND METHOD OF MANUFACTURE

A method for manufacturing an open cell HIPE foam structure imparted with color is disclosed. The method may include steps of: suspending dry pigment particles in a suspending medium to create a first suspension; providing an oil phase component blend including at least one monomer; providing an aqueous phase component solution; providing an initiator solution; blending the first suspension with the oil phase component blend to create a second suspension; blending the second suspension with the aqueous phase component solution and the initiator solution in water:oil ratio of at least 2.85:1 by volume, to create a water-in-oil HIPE having a continuous phase comprising the second suspension; and polymerizing monomer components of the oil phase component blend. The associated pigment-in-monomer second suspension, resulting open cell HIPE foam imparted with color. Absorbent articles made therefrom are also disclosed.
