  • Patent number: 10427419
    Abstract: Provided is a textile printing method that may effectively suppress the risk of ink smearing and that may allow a cured water-soluble, UV-curable resin to be adequately stripped off a fabric so as to dye the fabric in high quality color. A textile printing method includes a pretreatment step of discharging a treatment ink from an inkjet head for treatment toward a fabric to apply the treatment ink to the fabric; a dyeing step of discharging a textile printing ink from an inkjet head for textile printing toward the fabric to apply the textile printing ink to the fabric. In the dyeing step and the pretreatment step, the textile printing ink and the treatment ink are irradiated with ultraviolet light after a respective one of the inks is applied to the fabric.

    Abstract: In a method for producing a lactic acid oligomer by subjecting an aqueous lactic acid solution to a polycondensation reaction under microwave irradiation, the polycondensation reaction is carried out under reduced pressure in the absence of a polymerization catalyst and an organic solvent. An initial polycondensation reaction is carried out under normal pressure, and thereafter, a reaction is carried out under reduced pressure. The pressure is reduced stepwise to give a final pressure of 2000 Pa or less. A lactic acid oligomer which has a high purity and is safe from hygiene point of view can be obtained at a low cost in a short time.

  • Patent number: 8106109
    Abstract: The invention concerns a dental filling material with dual hardening mechanism, wherein i) a first hardening mechanism is based on a photocuring reaction, preferably a radical reaction, and ii) a second hardening mechanism is dependent on H2O as a reactant, especially as a ligand. Preferably, the second hardening mechanism is a gypsum-type reaction. Owing to the expansion of the composition an excellent marginal seal can be achieved, while the first hardening mechanism allows for a rapid cure on demand.
