  • Patent number: 11970644
    Abstract: Provided is a method for peeling a PSA sheet adhered on a polarizing plate. The PSA sheet has a PSA layer. The PSA layer includes a layer A forming at least one surface of the PSA layer. Of the polarizing plate, the surface to which the PSA sheet is adhered is corona-treated or plasma-treated. The peeling method includes a water-peel step in which the PSA sheet is peeled from the polarizing plate, in a state where an aqueous liquid exits at the interface between the polarizing plate and the PSA sheet at the front line of peeling the PSA sheet from the polarizing plate, with the aqueous liquid allowed to further enter the interface following the movement of the peel front line.

  • Patent number: 5605921
    Abstract: The present invention relates to a compound represented by the general formula (1) or its salt, a process for producing the same, and an antifungal agent comprising the same as an effective component: ##STR1## wherein R.sup.1 represents a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group bonded through a carbon atom in the ring to the main chain; R.sup.2 presents a hydrogen atom, a fluorine atom or a substituted or unsubstituted alkyl group; and R.sup.3 represents a cyano group, a thioamido group or a group represented by the formula ##STR2## in which R.sup.4 is a hydroxyl group or a group of the formula ##STR3## (R.sup.7 and R.sup.8, which may be the same or different, are hydrogen atoms or substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, aryl, amino, alkoxy, hydroxyl or heterocyclic groups, and may form a substituted or unsubstituted heterocyclic group together with the nitrogen atom to which R.sup.7 and R.sup.8 attach), R.sup.
