  • Patent number: 6652602
    Abstract: A process for the continuous dyeing of plastic films, such as polyethylene terephthalate, is characterized by passing the film through a dye bath comprised of dye stuffs dissolved, suspended or dispersed in a liquid carrier comprised at least in part of a polymer, preferably a polyol, having at least one free hydroxyl group and a molecular weight within the range of from about 200 to about 600. The hydrogen bonding provided by the hydroxyl group, together with the high molecular weight and high boiling point of the polyol, mitigate against migration of the dye stuff out of the film, i.e., fading of the film, and impart long lasting color fastness to the film. Rapid diffusion of the dye bath into the film is enhanced by thermal and ultrasonic energization of the bath.

  • Patent number: 6443996
    Abstract: A decorative dye colorant for use on various types of natural stone, such as granite, marble, limestone, and soapstone. The colorant is formed by mixing a solvent soluble dye with a suitable solvent, such as a ketone or an alcohol to form a dye solution. The solvent enables the dye to penetrate easily into the pores or openings located in the surface of the stone to color the stone so as not to mar the appearance of the surface of the stone. The dye is resistant to removal or discoloration, but may be removed by extended contact of certain chemicals with the dye. To permanently prevent the removal of the dye, a sealer is applied over the dye to prevent any such materials from contacting the dye. The sealer is comprised of an aliphatic urethane mixed with the alcohol xylol that also includes ultraviolet light resistant properties to prevent the dye from fading over time.

  • Patent number: 6136043
    Abstract: The present invention is directed to polishing pads useful in determining an end to the useful wear life thereof. In a simple embodiment of the present invention, a polishing pad that is used with slurries is dyed on one side in a manner that causes the dye to permeate the pad to a limited depth that does not cause total coloring. Another embodiment of the present invention involves a fixed abrasive pad that has fixed abrasives embedded into the pad to a selected depth where at least one color level is within the portion of the pad that contains the fixed abrasives. After dyeing the pad, the pad is attached to the polishing platen. During the polishing operation, a color change signals a time to stop the polishing operation and change the pad. With multiple colors in the pad, limited only by the ability to dye the pad with uniform depth levels, characteristic wear patterns can be observed and adjustments made accordingly to prolong and optimize pad life.

Those particles having a diameter of greater than about one micron also can be used to reduce the shiny appearance of visible softener spots which occasionally are present on fabrics treated with said fabric softening compositions and to maintain a relatively constant viscosity of the molten softening composition.

  • Patent number: 4655787
    Abstract: A process for the deposition of a film of an electrophoretic resin upon the surface of a substrate which comprises the steps of(i) electrophoretically depositing from a bath comprising water, a water miscible organic solvent and the resin, a film of the resin upon the surface of the substrate(ii) immersing said film in a solution of a solvent dye in a solvent medium comprising water, a water miscible organic solvent and a hydrotrope, the amount of said solvent dye dissolved in said solvent medium being sufficient for the absorption into the resin film of sufficient dye to impart the desired coloration to the resin film, the amount of said hydrotrope and said solvent being sufficient so that said amount of such solvent dye will dissolve in the solvent medium and(iii) curing the resin.

  • Patent number: 4591360
    Abstract: In a method in which containers, such as cylindrical metal cans, are printed by means of dye diffusion transfer, from a flexible paper carrier which is heated to shrink the carrier into intimate contact with a dye receptive coating on the surface of the container, and to effect dye transfer, the carrier has a weight of 35-110 grams per square meter, an equilibrium moisture content of 2-15% when exposed to air with a relative humidity of 50%, and is applied to the container so that the direction of grain of the paper is parallel to the axis of symmetry passing through the center of the base of the container.

  • Patent number: 4487609
    Abstract: The invention relates to powdered, stably dispersible dye formulations which do not foam on application, and to a process for their preparation. In addition to containing one or more disperse dyes and an anionic dispersant or mixture of dispersants, these formulations contain 0.01 to 10% by weight, based on the final formulation, of a non-ionic reaction product of ethylene oxide and propylene oxide with a low molecular polyol, said reaction product having a molecular weight in the range from 200 to 5000 and a cloud point in the range from -20.degree. to +130.degree. C. The formulations are particularly suitable for dyeing under HT conditions in half-filled dyeing machines.

  • Patent number: 4465489
    Abstract: Metal containers, such as cans, are printed when empty by means of dye diffusion transfer, the dyes being first printed on to a paper web which is cut into individual carriers. Each carrier is secured, somewhat in the manner of a label, to a container by a water-soluble adhesive so that, upon being heated to effect dye transfer, the carrier comes into intimate contact with a suitably receptive coating, pre-applied to the container, solely by virtue of its own shrinkage. The carrier and adhesive are subsequently removed by water spray.

  • Patent number: 4411667
    Abstract: This invention relates to a method of transfer printing in which a continuous length of strip is coated with a thermosetting material e.g. and alkyd, polyester, polyurethane or epoxy paint, and brought into contact immediately after curing with a continuous strip of printed material. The temperature of the strip at this time lies between 180.degree. C. and 280.degree. C. and the contact is effected during the passage of both strips between resiliently surfaced rollers at a pressure of at least 50 p.s.i., the ink print being transferred to the strip by sublimation.

  • Patent number: 4406662
    Abstract: A process of heat transfer printing the surface of a filled polymeric article, wherein the filled polymeric article consists essentially of an inorganic filler, preferably alumina trihydrate, and a polymer with an affinity for disperse dyes, preferably polymethyl methacrylate. A desired design is printed onto a carrier using sublimable disperse dyes. The filled polymeric article is preheated, the carrier supporting sublimable disperse dye is placed in intimate contact with the preheated article, and sufficient heat is applied to cause the dye to sublime, then diffuse into the surface of the article.
