Clariant offers paper manufacturers new opportunities to achieve the highest possible whiteness levels for printing and writing paper with the launch of Leucophor® VHR liquid. The optical brightening agent (OBA) is the latest addition to Clariant’s innovative Leucophor range. Leucophor VHR is a urea-free, brilliant, high white OBA. Designed primarily for size-press applications, Leucophor VHR gives state-of-the-art performance with ColorLok™ Technology in size-press applications to make ColorLok™ Paper. The OBA also maintains excellent performance with standard size-press applications. ColorLok Paper is a new standard developed by HP and International Paper that improves ink drying speed and definition on office papers.

Andrew Jackson, global product manager at Clariant comments: “Leucophor VHR is unique not only in giving the market a new level in whitening performance, but its compatibility with papers containing ColorLok Technology is second to none. We fully expect ColorLok Technology to become the standard in office and printing papers. We are excited to be at the forefront in offering a brightening agent that is compatible with ColorLok Technology’s capabilities.” Clariant, www.paper.clariant.com
