On June 1, 2016, Kao Corporation (President and CEO: Michitaka Sawada) concluded an agreement to acquire Collins Inkjet Corporation (Headquarters: Ohio, U.S.) through a Kao Group company in the U.S.

Kao has been developing water-based pigment dispersions (pigment dispersing liquids) and ink to propose a new value in the inkjet ink market for industrial printing.

By further applying "pigment nano dispersion technology"*1 cultivated by Kao for years, in March this year Kao succeeded in developing the world's first water-based pigment inkjet ink*2 for printing on film materials used in flexible packaging.*3 With a VOC-free design*4 , the newly-developed ink allows for the supply of high-quality, environmental impact-reduced*5 printed materials.

Collins Inkjet Corporation, based in Cincinnati, Ohio, U.S. is engaged in development, manufacturing and sales of inkjet ink and related equipment. The company was an early entrant into the rapidly growing inkjet ink market for industrial printing. With its advanced ink designing technologies responding to a wide variety of inkjet heads and its reliability, the company has built a wide customer network. Collins Inkjet continues to focus on ink development to broaden the application range and expand the business globally.

By taking advantage of newly acquired technologies, manufacturing systems and sales networks from Collins Inkjet in addition to its own technologies, Kao will provide global customers with its innovative products and services that can contribute to the mitigation of environmental impact.

Outline of Collins Inkjet Corporation
• Company name: Collins Inkjet Corporation
• Established: 1990
• Location: Ohio, U.S.

The acquisition will be completed in July 2016.


*1 Pigment nano dispersion technology
The technology for the nano-sized pigment dispersion coated with Kao's originally designed functional polymer. By applying this technology, Kao developed water-based pigment dispersions for inkjet ink (pigment dispersing liquid) and started production and sales of inkjet pigment dispersions and ink that ensure high-speed and high-quality printing. Kao is promoting its ink business extensively specifically in the field of office and commercial printing market.

*2 About the world's first water-based pigment inkjet ink
- Pigment ink: Water-based pigment inkjet ink that reduces environmental impact with a VOC (volatile organic compounds)-free design (for line head printer)
- Survey of literature regarding the world's first
Searched and confirmed using SciFinder (technology-related literature database) and brochures supplied by major device manufacturers that market in North America, EU, China and South Korea.
