  • Patent number: 8002884
    Abstract: The invention relates to a process of ink jet printing a radiation-curable ink from a printer having a de-wetting faceplate onto a substrate in which the ink is such that it has an advancing contact angle on the substrate of no more than 22° and a receding contact angle on the faceplate, after a period of contact of one month, of greater than 28° . The invention also provides a radiation-curable ink for use in an ink jet printer having a de-wetting faceplate, the ink having a receding contact angle on a material having a surface energy in the range of 16 to 20 dyne/cm of greater than 28° after a period of contact of one month and having an advancing contact angle on a substrate having a surface energy of less than 30 dyne/cm of no more than 22°.

  • Patent number: 7989031
    Abstract: This invention relates to a component surface (side section 1a), in particular a vehicle surface, with a three-dimensional surface texture. This invention further relates to a method for the creation of a component surface (side section 1a), in particular a vehicle surface, with a three-dimensional surface texture. To keep the effort and expense required for the achievement of a three-dimensional surface texture low, the invention teaches that a film is glued to the component surface (side section 1a), which film has been provided prior to the gluing with a plurality of coats of paint, each using the screen printing process, which in their totality form a three-dimensional surface texture.

  • Patent number: 7935183
    Abstract: A temporary aqueous aerosol paint composition comprising an aqueous paint component, including an aqueous solvent, and an aqueous propellant component. At least one embodiment of the composition includes an amount of water as the aqueous solvent. The composition is formulated to minimize and/or eliminate the hazards presented by various volatile and non-volatile organic compounds present in known aerosol paint compositions, by eliminating or minimizing inclusion of such organic compounds. Further, the composition is developed to facilitate enhanced degradation in a short period of time, while also including elements to increase the performance when in use. A variety of pigment compounds may be used in the composition, permitting a variety of applications. The present invention is also directed to a method for preparing the temporary aqueous aerosol paint composition. This method includes adding the compounds to a reaction vessel and mixing thoroughly via a plurality of addition steps and mixing cycles.

  • Publication number: 20110036928
    Abstract: The subject invention concerns methods revealing surface imperfections on an object comprising the steps of: coating the surface to be inspected with a composition comprising an opaque, water-dispersible liquid, sufficiently surface-adherent and with surface-wetting properties as to create a gloss finish, at least before the liquid dries, on the restored area; inspecting the surface to check for imperfections; and removing said composition with water. The method may also include a step of marking the surface, through the wet composition layer, to indicate the location of imperfections discovered. Also described are compositions and delivery systems suitable for carrying out the method comprising aqueous dispersions of a pigment and a resin, especially a polysaccharide resin.
