  • Patent number: 11578231
    Abstract: The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide surface protection to treated articles including reduced soiling tendency, reduced cleaning effort and improved soil repellancy, as well as providing bacteriostatic properties to treated surfaces that thereby gain resistance to water, environmental exposure and microbial challenge. Treatment means and compositions are provided that employ associative polyelectrolyte complexes formed by combining a water soluble cationic first polyelectrolyte with a water soluble second polyelectrolyte bearing groups of opposite charge to the first polyelectrolyte under suitable mixing conditions where the one polyelectrolyte present in molar excess is added in the form of a first aqueous solution during a mixing step to a second aqueous solution comprising the oppositely charged polyelectrolyte present in molar deficiency.

  • Patent number: 11574821
    Abstract: A substrate treating method, liquid and apparatus are provided which can reduce the amount of sublimable substance used for the drying of a substrate while reducing the collapse of pattern. The substrate treating method includes a step of supplying a liquid to the pattern-formed surface of the substrate, a step of solidifying the liquid on the pattern-formed surface to form a solidified body and a step of subliming the solidified body so as to remove it from the pattern-formed surface. The substrate treating liquid includes a molten sublimable substance and a solvent, the freezing point of the sublimable substance being higher than the freezing point of the solvent. When the sublimable substance and the solvent are separated, the sublimable substance is settled and in the solidification step, the settled sublimable substance is solidified to have a height equal to or higher than the height of a pattern.
