    Abstract: A fluorescent paste that can form a fluorescent film and can be manufactured without a binder resin and has a high recording density and peel resistance Fluorescent fine particles each coated with a film formed of a film compound having a reactive group and a curing agent having a plurality of crosslinking reaction groups each reacting with the reactive group to form bonds are blended with a solvent to manufacture fluorescent paste. The fluorescent paste is applied to a substrate coated with a film formed of a second film compound having a second reactive group and is cured by crosslinking reactions between the reactive group and the second reactive group, and the crosslinking reaction groups to form a fluorescent film.

  • Patent number: 8815970
    Abstract: A method of preparing polyurethane prepolymer does not require using a toxic isocyanate monomer (manufactured by harmful phosgene) as a raw material. Epoxy resin and carbon dioxide are used as major raw materials to form cyclic carbonates to be reacted with a functional group oligomer, and then amino groups in a hydrophilic (ether group) or hydrophobic (siloxane group) diamine polymer are used for performing a ring-opening polymerization, and the microwave irradiation is used in the ring-opening polymerization to efficiently synthesize the amino-terminated PU prepolymer, and then an acrylic group at an end is added to manufacture an UV cross-linking PU (UV-PU) oligomer which can be coated onto a fabric surface, and the fabric is dried by UV radiation for a surface treatment to form a washing-resisted long lasting hydrophilic or hydrophobic PU fabric.
