Abstract (en)
[origin: EP0671655A2] An improved method of hardening a hydrophilic colloid is detailed. The hardening results in a stronger matrix and less water pickup. These and other advantages are obtained by hardening with a combination of at least one hardener chosen from Formula I and at least one hardener chosen from Formula II: <CHEM> The substituents are defined.
