  • Patent number: 5240767
    Abstract: A nonwoven fabric, particularly composed by long-stock synthetic resin yarns such as polyethylene and polypropylene is provided at one or both surfaces thereof with an ink-setting layer formed by coating, drying and curing a resin composition containing some of acrylic resins, synthetic rubbers and polyester resins. The ink-setting layer is excellent in the transfer property and fixing ability to an oil ink which is ordinarily used for offset printing, and prevents the nonwoven fabric from being swelled or transformed by a petroleum high-boiling-point solvent contained in the oil ink. Preferably, a low-temperature cross-linking agent is incorporated with the resin composition of the ink-setting layer so as to complete cross-linking of the resin composition at a low temperature at which heat shrinkage or heat damage of the nonwoven fabric will not be caused, in a shortened period of time.
