Recently, Shanghai Textile Research Institute has successfully developed stealth printing technology, which is used in security label. The technology has been applied to get protection under Chinese patent law.
Stealth printing is a new type of printing technology. Polymer materials show different "pattern" at different temperatures; by this stealth printing technology, the fabric will not show printed pattern, but will show just when wet.
Moreover, if products like umbrellas and raincoats are made with this stealth printing technology, these will show colourful patterns in the rain, and the patterns can appear and disappear tens of thousands of times
