Abstract
The present invention provides a translucent absorbent composite having a substrate with a light transmittance of at least about 60% and a flexible superabsorbent binder polymer composition applied to the substrate. The polymer composition may be prepared from the reaction product of a monomer solution including at least 15% by mass monoethylenically unsaturated monomer selected from carboxylic acid, carboxylic acid salts, sulphonic acid, sulphonic acid salts, phosphoric acid, or phosphoric acid salts; an acrylate or methacrylate ester that contains an alkoxysilane functionality; a copolymerizable hydrophilic glycol containing an ester monomer; an initiator system; and a neutralizing agent. The unsaturated monomer is neutralized to at least 25 mol % and the flexible superabsorbent binder polymer composition has a residual monoethylenically unsaturated monomer content of less than about 1000 ppm. The absorbent composite has a light transmittance of at least 45%. Also provided are absorbent articles containing the absorbent composite.
