  • Patent number: 10982099
    Abstract: A surface marker resin formulation is provided that includes a linear aromatic polyester or a co-polymer thereof. The resin is dissolved or dispersed in a solvent exclusive of naphtha. An inorganic particulate having an average maximal linear extent of between 10 and 130 microns present from 22 to 41 total weight percent. A process of marking a surface includes two articles being brought into a pre-selected alignment to define a surface. A continuous bead is applied to the surface. The solvent evaporates to a state of dry-to-touch in a time of between less than 60 seconds to mark the surface. The formulation is readily applied from a pen to achieve a controlled bead width. The drying of the formulation by solvent evaporation yields full hardness in 24 hours under standard temperature and pressure as measured at 0% humidity.

Such a polymeric composite material can be prepared by a method including causing predetermined microbes cultured in a liquid culture medium to produce bacterial cellulose, collecting and drying the produced bacterial cellulose into a powdery state and mixing the powdery bacterial cellulose and a biodegradable polymeric material to produce a composite material.

  • Patent number: 6264732
    Abstract: A puncture preventive sealant capable of reducing the content of cellulose fibers for suppressing the cost of the sealant while keeping a high sealing performance due to the cellulose fibers. A sealant, which is filled in a sealant chamber defined in a tube adjacently to an air chamber, contains synthetic fibers and cellulose fibers in a solvent. The content of the synthetic fibers is in a range of from 75 to 90 wt % and the content of the cellulose fiber is in a range of from 25 to 10 wt %. Since the sealant is filled in the sealant chamber having a capacity significantly smaller than that of the air chamber, the separation of the synthetic fibers due to a centrifugal force substantially exert no adverse effect on the characteristics of the sealant. Accordingly, the content of the cellulose fibers can be set at such a minimum value so as to block a large puncture hole. As a result, it is possible to reduce the cost by reducing the content of the cellulose fibers.

  • Patent number: 6214907
    Abstract: A biologically degradable polymer mixture is proposed which consists essentially of starch and at least one hydrophobic polymer. The hydrophobic polymer is in this connection at least substantially biologically degradable and thermoplastically processable and the mixture with the starch comprising a polymer phase mediator or a macromolecular dispersing agent so that the starch is present in the mixture as disperse phase with the hydrophobic polymer as continuous phase, and the phase mediator or the dispersing agent is responsible for the molecular coupling of the two phases. As starch there is preferably used thermoplastic starch which has been prepared substantially with the exclusion of water by means of sorbitol or glycerol. The production of the biologically degradable polymer mixture is also carried out substantially with the exclusion of water.

  • Patent number: 6063842
    Abstract: The present invention relates to a thermal transfer ink layer composition, wherein polyvinylacetal resin and cellulose derivatives are used in a mixture for the binder in the thermal transfer ink layer composition of the sublimation thermal transfer ink ribbon, or the another type of a binder is mixed into the mixture of polyvinylacetal resin and cellulose derivatives and so used therein. As a result, the adhesion between the thermal transfer ink layer and substrate film, and the gradation property of printed images are improved as compared to the case in which the respective binders are used individually. More particularly, the present invention relates to the thermal transfer ink layer composition of the sublimation thermal transfer ink ribbon, which can yield high quality images by means of the aforementioned improvements.

  • Patent number: 6046259
    Abstract: A stable aqueous dispersion containing cellulose ester, the dispersion being polymeric microparticles comprised of cellulose ester and a polymer formed from at least two different vinyl monomers of which at least one vinyl monomer is polyethylenically unsaturated. The dispersion of microparticles is formed by a high stress technique prior to polymerization of the vinyl monomers in the presence of the cellulose ester. Typically the dispersion also contains surfactant. A method of making the stable, cellulose ester-containing aqueous dispersion by (a) mixing together a cellulose ester, at least two vinyl monomers of which at least one vinyl monomer is polyethylenically unsaturated, surfactant, and water to form an emulsion; (b) particulating the emulsified mixture of (a) into microparticles by a high stress technique; and (c) copolymerizing the vinyl monomers in the cellulose ester-containing particulated emulsion of (b) to form a crosslinked polymer within the microparticles of the dispersion.
