Abstract
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.
Claims20
An inkjet composition comprising a crosslinking agent, a property-sensitive agent, a co-polymerizable agent, a colorant and a second carrier, said property-sensitive agent is sensitive to a change in a chemical and/or physical property, such that upon effecting said change on a surface of an object the inkjet composition congeals on said surface to thereby form an image on said object, wherein said crosslinking agent is a formaldehyde-free crosslinking agent and said image is substantially devoid of formaldehyde emission, said formaldehyde-free crosslinking agent is a heteroaryl polycarbamate.
