Abstract: An apparatus for displaying procedural information cards on a computer video monitor includes a central shaft having an upper end and a lower end, the upper end capped by an upper cross member having an upper planar arm extending in one direction from the shaft, and an upper arcuate arm extending the opposite direction. The lower end is terminated by a lower cross member having a lower planar arm and a lower arcuate arm. The apparatus includes means for affixing the apparatus to a surface on a computer video monitor. The arcuate arms of the apparatus extend outwardly from the monitor to facilitate installation and flipping of the cards. Each of the arcuate arms comprises a generally semi-circular ring, and means for preventing inadvertent removal of the cards from the arcuate arms.

Abstract: A dry colorant composition is disclosed and contains (a) pigment; (b) inert carrier; and (c) rheological additive having the structure: P—(U—Y)s wherein P is the residue of an organic colorant, Y is a polyalkylene oxide or polyalkylene moiety, U is a linking moiety covalently bonding Y to P, and s is an integer from 1 to 3.

Abstract: Dispersants for pigments as well as dispersions of pigments containing them, and compositions such as inks and coatings containing them are described. The dispersants are the reaction product of a dialkylsuccinyl succinate and an amine.

Abstract: Phthalocyanine blue pigments and pigment dispersions for water-borne inks and coatings are described. The pigments are produced by dry milling phthalocyanine blue and a polymeric dispersant, optionally with inorganic fillers and other additives, to obtain a material with improved coloristic, rheological, and stability properties. The resulting activated crude is then processed directly into water-based pigment dispersion with additives and/or surfactants to facilitate conversion to pigmentary form while maintaining the desirable green and clean shade.

Abstract: Pigment dispersions that when used in printing ink having a relative interfacial tension drop of less than 1.5, and offering an ink viscosity of less than 150 Pa.s, and containing at least 45 wt. % pigment.

Abstract: A polymeric dispersant of the structure: wherein R1 is selected from the group consisting of H, CH3, and a combination thereof, and n is an integer from 4 to 200, for use in printing inks.

Abstract: An apparatus for displaying procedural information cards in the workplace includes a central shaft having a ring portion at each end adapted to capture cards having slots. The central shaft may be releasably captured in a channel of a universal mount or a swing arm portion. Removal of the shaft portion from the channel permits the shaft to be split open, thereby opening the rings. Alternatively, the shaft portion may be used alone (without a mount or swing arm) to hold a quantity of cards. The swing arm may be hinged upon a base portion and attached to the peripheral surface surrounding a computer video monitor. When affixed to a monitor, the semicircular rings facilitate easy installation and flipping of instructional cards.

Abstract: A process for preparing transparent Pigment Yellow 138 by grinding Pigment Yellow 138 in the presence of a grinding agent, preparing an aqueous slurry of the ground particles, and filtering the slurry resulting in a filter cake containing particles of transparent Pigment Yellow 138. In addition, a process for improving color strength of an ink and/or plastic composition is also disclosed by adding transparent Pigment Yellow 138 to the composition.

Abstract: Solvent-free, energy curable low viscosity gravure and non-conductive ink jet inks which contain a pigment; a rheological additive having the structure P—(U—Y)s, wherein P is the residue of an organic pigment or dye, Y is a polyalkylene oxide moiety, U is a linking moiety covalently bonding Y to P and s is an integer from 1 to 3; and an energy curable liquid vehicle which may be a cationic, thermal cationic or a free radical initiated polymerization system, cured by actinic radiation; and optionally containing a photoinitiating system.

Abstract: A process for improving the heat stability of Pigment Violet 23 by conditioning crude Pigment Violet 23 in the presence of about 1 to 10 wt. % of Pigment Violet 23 by-products (1), (2) and (3).

Abstract: An etheramine pigment dispersing salt for enhancing the dispersion performance of an organic pigment composition adding to 100 parts by weight of pigment about 1 to 40 parts by weight of an etheramine pigment dispersing salt.

Abstract: A variety of mounting systems are provided for mounting display cards, photographs, or other material to a computer display device of a computer system. The display cards may include printed indicia showing, for example, a summary of useful software commands for use with software programs running on the computer system. In one embodiment, a pair of mounting units or hinges are provided for pivotably mounting the display cards to the computer display device so that selected cards may be pivoted into a position adjacent to a front surface of the display screen for ease of viewing. In another example, a transparent pocket is provided for receiving the display cards, with the pocket being pivotably mounted to the display device via the mounting units. By providing a pocket, the display cards are protected while in use. Also, the display cards need not include any mounting holes or other attachment elements for direct attachment to the mounting units.
