  • Patent number: 4284453
    Abstract: A contrasting color is imparted to the decorative surface of a decorative laminate by inserting a pigment coated release sheet between the molding caul and the decorative surface during the molding operation, with the pigment facing the decorative surface. Upon application of heat and pressure during the formation of the laminate, color is transferred from the release sheet to the decorative surface. A suitable technique is also used to emboss or impart surface texture to the decorative surface during molding. Thereafter, the textured surface is subjected to rubbing or brushing to remove more color from the embossed or raised areas than the debossed areas, thereby highlighting or imparting a shaded effect to the textured surface.

  • Patent number: 4275905
    Abstract: A substantially colorless marking liquid, particularly for use in pressure-sensitive record material, comprising (a) a colorless chromogenic material, (b) a solvent for said chromogenic material and (c) an additive for controlling CB decline. The additive for controlling CB decline, i.e., controlling the capability of the CB sheet to produce an image of satisfactory intensity even after exposure of the CB coating to light, includes certain chromogenic materials such as Pyridyl Blue and phenol derivatives having a free reactive (ortho- or para-) position. The marking liquid helps to prevent CB decline in, for example, carbonless copy paper, a long-standing problem in the art.

  • Patent number: 4250211
    Abstract: A method and apparatus for applying a film of liquid pigmented coating material to a moving web of paper at, and between, a low limit of two pounds per ream per side and a high limit of fifteen pounds per ream per side. The method and apparatus utilize a reservoir of liquid coating material established between a forward liquid coating material seal and a rearward pneumatically loaded and clamped doctor blade spaced a small distance of a few inches or less from the liquid seal. The reservoir is pressurized in the range of 7 to 150 inches of water so that the coating material is applied under pressure to the moving web and then almost instantaneously wiped by the doctor blade. The reservoir is formed by two relatively movable, sealed members which may be opened for easy cleaning, and may have one or more internal coating material distribution headers at its end opposite the web to uniformly distribute the coating material.

  • Patent number: 4243319
    Abstract: In an illustrated embodiment, brightness, color, opacity and fluorescent contribution to brightness are measured by an on-line sensing head providing for simultaneous measurement of transmitted and reflected light. By measuring two independent optical parameters, paper optical properties of a partially translucent web are accurately characterized substantially independently of paper grade and weight. The instrument is designed so as to be capable of transverse scanning of a moving paper web on the paper machine, and so as to monitor desired paper optical characteristics with sufficient accuracy to enable on-line control of the optical characteristics of the paper being manufactured.

  • Patent number: 4217769
    Abstract: A method for making an application or dip roll for applying a coating, such as an aqueous clay and starch solution, from a trough, onto a moving web on a papermaking or coating machine. The roll comprises a roll cylinder having a hard, outer surface which is not subject to attack by the coating to be used. A plurality of minute indentations are formed in the outer surface of the roll to enhance the transfer of coating from the trough to the roll. Preferably, the roll is first provided with a smooth surface finish. Then the plurality of indentations are formed by shot blasting the outer surface of the roll with hard shot. If a shot of a material subject to attack by the coating is used, the roll may be subsequently blasted with another material, not subject to such attack, so as to remove any fragments of the first shot that might have become embedded in the roll.

  • Patent number: 4211437
    Abstract: This invention relates to paper, or like sheet material, having a coating comprising minute, liquid-containing, pressure-rupturable capsules, and also larger, non-rupturable kaolin-containing stilt capsules arranged in interspersion and in close juxtaposition. In the preferred embodiment the smaller capsules contain a liquid marking agent. The capsules, large and small, are interspersed as to size, and are closely spaced on the sheet, so that an intentional impact directed on a small area of the coating will crush substantially all of the small capsules in the area and result in the release of liquid marking agent, whereas a casually applied pressure will rupture relatively few of the small capsules in the area. The marking liquid may be a colorless chromogenic color reactant. The small capsules on a sheet containing said marking liquid may be associated with other color forming materials on said sheet, or alternatively said color forming materials may be contained on another contacting sheet.

  • Patent number: 4197346
    Abstract: A self-contained pressure-sensitive record material comprising a substrate and a coating thereon of an interspersed mixture of pressure-rupturable capsules of an oily solvent solution of a substantially colorless basic chromogenic material and capsules of solid co-reactant acidic resin particles, said co-reactant acidic resin being capable of producing a color upon contact with the chromogenic material. The capsule mixture is applied to the substrate in a single coating step, resulting in a greater production efficiency. The resulting record material provides better imaging characteristics with less print bleed than self-contained systems known in the prior art.

  • Patent number: 4159874
    Abstract: In an illustrated embodiment, brightness, color, opacity and fluorescent contribution to brightness of single thickness sheet material are measured by an optical measuring system providing for simultaneous measurement of transmitted and reflected light. One embodiment is designed so as to be capable of transverse scanning of a moving paper web on the paper machine. An optical window member of translucent diffusing material serves as a backing for the web for reflectance measurements and is in series with the web with respect to transmittance measurements. The optical window itself is selected as to its reflectance and transmittance so as to provide for periodic standardization of the instrument in an off-sheet position. Another embodiment will measure the same optical properties of single thickness sheet material selectively, with spectral response filters for characterizing such optical properties and with a series of narrow band filters.
