  • Laser-sensitive coating composition
    Patent number: 9045619
    Abstract: The present invention provides a laser-sensitive coating composition comprising titanium dioxide in the anatase form or polymeric particles comprising a polymeric matrix comprising one or more water-insoluble polymers and titanium dioxide in the anatase form encapsulated in the polymeric matrix, and a polymeric binder. The present invention also provides a process for the preparation of the compositions, processes for preparing substrates coated with the coating compositions, substrates coated with the compositions, processes for marking the substrates coated with the compositions, and marked substrates obtainable by the latter processes.
    Type: Grant

  • Preparation of polymeric aryl sulfonamide
    Patent number: 7098296
    Abstract: A method of preparing a polymeric aryl sulfonamide is described which consists of reacting aryl sulfonyl with a polymeric amine in the presence of an acid acceptor. Also, another method of preparing a polymeric aryl sulfonamide is disclosed and consists of: reacting an aryl sulfonyl with a polymeric diamine in the presence of an acid acceptor to result in a linear oligomeric molecule; and reacting the linear oligomeric molecule with a monoamine or an aryl monosulfonyl in the presence of an acid acceptor. The use of polymeric aryl sulfonamides as pigment dipersants and wetting agents is also disclosed.
