  • Publication number: 20090014141
    Abstract: The specification discloses papers suitable for liquid electrophotographic printing (“LEP”) and a method for making such papers. According to the method, a papermaking furnish containing cellulosic fibers is formed into a fibrous web on a papermaking machine and at least partially dried. The web is then treated with a sizing composition comprising starch, an acrylic acid polymer, a polyglycerol ester, and water. The treated web is dried and calendered to a final desired caliper. Since the sizing composition is an aqueous mixture, it may be applied to the web on-line during production of the paper on the papermaking machine, thereby avoiding the expense and inconvenience of conventional off-line methods used to make existing LEP papers. The resulting paper exhibits at least 80% and preferably above 90% toner adhesion as measured by the tape pull tests used for the assessment of papers printed by LEP.

    Abstract: A colored particle (e.g., a spherical particle) comprising an organic solid component (e.g., a polymer component) and a coloring agent (e.g., an oil-soluble dye, and an organic or inorganic pigment) is produced by eluting a water-soluble auxiliary component comprising at least an oligosaccharide from a composition having a disperse system, in which a particulate dispersed phase comprising the organic solid component and the coloring agent is dispersed in a matrix comprising the auxiliary component. The weight ratio of the polymer component relative to the auxiliary component may be about 55/45 to 1/99. The proportion of the coloring agent may be about 0.001 to 100 parts by weight relative to 100 parts by weight of the organic solid component. Such a process ensures conveniently and industrially advantageous production of a colored particle (e.g., a colored polymer particle) corresponding to the dispersed phase independently of affinity between the dispersed phase and the matrix.

  • Patent number: 7261759
    Abstract: A powder metal mixture comprises a lubricant powder conventionally used to produce powder metal parts in combination with a modified lubricant. A lubricant conventionally used to compact and sinter a chosen powder metal mixture is modified by adding to it starch particles smaller than the average metal particle, and optionally, micronized cellulose fibers in so small an amount that the modified lubricant is present in an amount less than 2% by weight of the mixture. The Hall apparent density and the Hall flow rate of a powder metal mixture made with the modified lubricant of starch or (starch+fibers) remains within the ranges deemed desirable for production of compacted powder metal parts. Using the modified lubricant in lieu of the conventional lubricant increases green strength of a part made by compacting the mixture and improves dimensional conformance.

  • Patent number: 7235594
    Abstract: The present invention relates to biodegradable plastic composition comprising rice powder and/or corn powder, which can be characterized in comprising 100 parts by weight of polyolefin matrix resin; 5 to 400 parts by weight of grain powder selected from the group consisting of rice powder, corn powder and mixture thereof. The biodegradable plastic composition according to the present invention can be manufactured in various forms such as injection molding product, sheet molding and blow molding product, which have excellent physical properties and product stability. The efficiency of waste disposable of the product manufactured with the composition can be remarkably improved since the rive powder or the corn powder contained in the composition can be degraded by microbes in the nature after a certain period. Therefore, the problems of soil, air, and sea pollution caused by burial or incineration of the wastes of conventional plastic molding product can be minimized.
