  • Patent number: 4835208
    Abstract: The present invention provides a process for applying a thermoplastic composition as a series of discrete droplets from a non-contact ink jet printing apparatus to form separate drops on a substrate moving relative to the apparatus, characterized in that the molten composition is thermally stable at the temperature of application and is applied at a temperature in excess of 100.degree. C.The invention can be used to apply the molten composition to a variety of substrates using on-demand or continuous non-contact ink jet application techniques. However, the invention is of especial use in the application of thermoplastic inks to non-porous substrates using an on-demand ink jet printer.

  • Patent number: 4722855
    Abstract: A process for painting substrates in web or tabular form using roller application wherein a primer or base coat layer of paint and a top coat layer of paint are applied is characterized in that in the application of one of the two layers of paint a paint is used which contains in a solvent or dispersing agent a crosslinkable or thermoplastic resin which is liquid at the processing temperature, 0.5 to 7% by weight in relation to the dry weight of the resin of an organic substance which is suspended or emulsified in the solvent or dispersing agent, the size of the particles or droplets of said substance lying between 3 and 60 .mu.m, said substance melting at the processing temperature and its surface differing from that of the resin, and where appropriate the conventional paint additives.

  • Patent number: 4714727
    Abstract: A basic aqueous emulsion composition that can be used as a treatment for cellulosic sheets or articles made of cellulosic fibers to provide improved water resistance by forming a discrete coating on the individual fibers that make up the sheet while not substantially limiting the compatibility of the treated sheet with aqueous glues, dyes or inks comprising a major proportion of water, a mixture of wax and rosin, an emulsion stabilizer and a chelating agent.

  • Patent number: 4614758
    Abstract: The present invention relates to the use of paraffin waxes or microwaxes in silicone pastes, in particular in kneadable compositions for the production of accurate impressions of teeth. The silicone pastes are preferably cold-vulcanizing two-component silicone rubber systems which are known per se and in which two pastes are mixed and then crosslink after about 2-5 minutes at room temperature.

  • Patent number: 4536218
    Abstract: Printed materials such as tickets, lottery forms, cards and contest forms, bearing a hidden message which is revealable by scratching off a covering opaque layer, are prepared by printing the message on the substrate, lithographing a protective layer such as a clear varnish or a pigmented varnish-ink over the hidden message, and then lithographing a hiding coat over the applied protective layer. The protective layer formulation and the hiding coat layer are both based upon compatible, preferably the same, film forming resin systems, and are deposited from a common solvent. The protective layer may provide a clear, colorless transparent film through which the message may be viewed, or a colored see-through layer, so that it constitutes one color layer also for the printing of other areas of the substrate.
