Our main products, color formers, are materials characterized by a chromogenic reversible reaction when met with acids. They were first adopted to pressure sensitive recording paper (non-carbon paper) and then to thermosensitive recording paper (thermal recording paper). Thermosensitive recording paper found its way from its original application to FAX paper, and expanded widely to bank ATM and cash register recording paper, labels for food and commodity distribution, traffic tickets, admission tickets, lotteries, etc. Such applications utilize one of the color former’s reversible chemical characteristics, which is to form colors by reacting with acids, however, recent technology is focused on utilizing the intrinsic reversible characteristic of color formers, from non-colored to colored and from the colored to non-colored, such as for thermo chromic materials, rewritable thermosensitive paper, erasable toner. etc.
Color formers are everywhere in our daily life although they may not be noticeable to everyone. We are committed to continue to offer new products, not only color formers, but also products that will make life richer and more convenient, as well as environmentally friendly products, by capitalizing on our expertise and experiences in designing and elaborating color formers.
