  • Patent number: 8956701
    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 polymeriz

  • Publication number: 20120238660
    Abstract: Method for dyeing a substrate prepared by curing a polymerizable composition having one monomer containing one episulfide group, the method including: providing a dye solution including a dye and a carrier in a solvent, the carrier being chosen from the compounds represented by the following formulae (1) and (2): wherein R1, R2, R3 and R4 are each selected from the group consisting of alkyl having from 1 to 10 carbon atom, H, —CH2SH, —CH2SCH2CH2SH, wherein m denotes an integer from 1 to 3; and at least partially immersing the substrate in the dye solution for a time sufficient to allow the effective tinting of the substrate.
