Abstract
The present invention concerns a process for tinting an article, comprising providing an article having a substrate and an ink receptive coating applied thereon, applying on said ink receptive coating a tinting solution containing at least one dye through ink jet printing, said ink receptive coating being obtained by curing an ink receptive coating composition comprising the at least partial hydrolyzate of a component A consisting of one or more compounds containing at least one polyalkylene oxide segment having at least three alkylene oxide units, said segment being chosen from polyethylene oxide, polypropylene oxide and polyethylene oxide-co-polypropylene oxide segments and at least one —Si(X)n hydrolyzable group, in which n is an integer ranging from 1 to 3, and the X groups, identical or different, represent OH groups or precursors of OH groups, and optionally, at least one silane component B, components A and optional component B being chosen such that a cross-linked structure is generated upon polymerization of said composition. The invention also concerns an ink receptive coating composition for use in the above process.
