FORMALDEHYDE-FREE INKJET COMPOSITIONS AND PROCESSES

摘要

Disclosed are a process for inkjet printing color images on various substrates using a formaldehyde-free crosslinking agent in the ink composition, which is therefore devoid of formaldehyde emission and suitable for health-aware manufacturing practices, as well as objects having images and designs printed thereon which are devoid of formaldehyde and therefore suitable for use by infants.
