Archroma grants patent license to Blankophor

REINACH, SWITZERLAND: Chemical company Archroma Management LLC said it has entered into a license agreement with Blankophor GmbH for Archroma’s patented “improved optical brightening compositions.”

The agreement recognizes Archroma as the sole owner of the European patent and grants a license to Blankophor GmbH as the first licensee to use the patented process.

“The patent recognizes once more the commitment of Archroma to the development of innovative solutions designed to meet the needs of our customers and, ultimately, the expectations of end users,” said Valerie Diele-Braun, president, paper solutions, Archroma.

“Even though we have a different view on the decision of the European patent office, we do respect their decision after we lost the opposition case against Archroma’s patent,” said Dr Bernd Hauschel, head of technology and intellectual property, Blankophor.

The improved optical brightening technology was developed by Archroma combining magnesium salts with optical brighteners. Papers treated with this process present enhanced brightness and whiteness levels, offering consumers a more pleasurable writing and printing experience. The patent covers mixed salts of most of the common paper optical brighteners containing magnesium cations.
