An apparatus for printing leather including an ink acceptor applicator that applies ink directly onto a surface of the leather; an ink applicator that applies ink to the ink acceptor and/or the leather surface; an additive applicator that applies additive onto the ink acceptor, the ink and/or the leather surface; a barrier having a surface configured to contact the acceptor, ink and additive on the leather surface; and a heater that heats the surface of the barrier to a predetermined temperature or a temperature within a selected temperature range such that the barrier, which is substantially impervious to the ink and has a melting point higher than the select temperature range, contacts at least the acceptor ink and additive on the surface directly to liquify the acceptor ink and additive into the leather and the acceptor, ink and additive fuses and penetrates into the leather.
摘要:
A novel photoreactive polymer is disclosed comprising a dendritic polymer core with at least one initiating functional group and at least one co-initiating functional group. The photoreactive polymers are useful in radiation curable compositions are varnishes, lacquers,printing inks and radiation curable ink-jet inks. The dendritic polymeric core is preferably a hyperbranched polymer.
