  • Patent number: 4599273
    Abstract: Surfactants which are blocked against surfactant action (identified herein as "photolabile blocked surfactants") by a photolabile protective or masking group but which, on exposure to actinic radiation, become unblocked are provided. Coating compositions in which surfactant is formed on irradiation are provided by blending the photolabile blocked surfactant with polymeric film-forming materials.Compositions containing the photolabile blocked surfactants are useful when employed as protective coatings on various substrates or as the adhesive in a pressure sensitive adhesive tape. Although initially well adhering to a substrate, such compositions may be readily removed from the substrate following exposure of the same to suitable radiation which unblocks the surfactant to permit it to regain its surfactant activity.

  • Patent number: 4493916
    Abstract: The present invention relates to a method of avoiding a too rapid curing reaction in production processes where a prepolymer is cured, giving an extension of the so-called pot life. By adding a small amount of a compound, whose structural formula comprises the metal-binding part ##STR1## to form complexes with transition metals catalyzing the curing reaction, an extension of the pot life is achieved without any negative influence on the qualities of the produced product. Preferably a tetracycline compound is added.
