摘要:
A coated substrate comprises a substrate and a coating on at least one surface of the substrate. The coating comprises a prepolymer, polymer, or resin produced, for example, by the reaction of (i) an isocyanate (e.g., a polyisocyanate), (ii) an active hydrogen-terminated colorant, and optionally (iii) at least one reactant selected from the group consisting of chain extenders, polyols, internal surfactants, and combinations thereof. Polymer dispersions suitable for use in making such coated substrates comprise such a prepolymer, polymer, or resin.
摘要:
Novel synthetic leather articles comprise a substrate and a coating applied to a surface of the substrate. The coating comprises a resin and a polymeric colorant. The polymeric colorant comprises a chromophore and an oligomeric constituent bound to the chromophore. Novel methods for producing synthetic leather articles using polymeric colorants are also provided.
摘要:
Improvements for in-mold polyurethane foam and/or resin products and the ability to provide surface coatings of such products exhibiting bright coloration and reduced colorant migration through utilization of easy-to-use polymeric colorants in simplified and environmentally friendly processing methods are disclosed. The inventive surface coating formulations include polyurethane-reactive polymeric colorants admixed with prepolymer and excess amounts of certain isocyanate compounds. Such a composition is applied (by spraying, for example) to a polyurethane prepolymer (for the production of the internal polyurethane article) which is then introduced within a mold in order to form a particularly shaped or configured polyurethane article with a colored surface coating. Upon curing through exposure to heat, the coating composition reacts with the introduced polyurethane prepolymer to form a surface over the target internal polyurethane. The excess isocyanate present within the surface coating has been found to provide surprisingly good non-migration and non-bleed properties to the polymeric colorant thereby permitting the addition of such a highly desired, high color space, and effective polyurethane colorant within such surface coatings. The specific method as well as colored polyurethane articles are also contemplated within this invention.
