Abstract:
A laminate comprising:a substrate; and a stain resistant and adherent layer on said substrate comprising the cross-linked reaction product of at least; an amino resin cross-linking agent and a reactive polyester resin including therein at least one repeat unit derived from a hydroxyl terminated polymer including repeat units from an oxetane having a pendant â€”CH2â€”Oâ€”(CH2)nâ€” Rf group , said reactive polyester resin being formed by the prereaction of a diacid with said hydroxyl terminated polymer including repeat units from an oxetane having a pendant â€”CH2â€”Oâ€”(CH2)nâ€” Rf group, and then in a separate reaction adding a diacid and a polyol to the reaction product of said diacid with said hydroxyl terminated polymer and reacting the same to form said reactive polyester resin, wherein said Rf group, independently, being a linear or branched alkyl group of 1 to 20 carbon atoms and a minimum of 25 percent of the hydrogen atoms of said alkyl group being replaced by F, or said Rf group, independently, being a perfluorinated polyether having from 4 to 60 carbon atoms, and n being from 1 to 3, and optionally up to 20 wt %, based on the weight of said hydroxyl terminated polymer, of a cyclic tetramer from the polymerization of an oxetane monomer having a pendant â€”CH2â€”Oâ€”(CH2)nâ€” Rf group wherein Rf is described above.
