    Abstract: There is provided a polyester-based primer composition including 100 parts by weight of a polyester resin, 1 to 20 parts by weight of water-dispersible particles, and water as a remainder. Since a polyester-based primer composition of the present disclosure is excellent in water resistance and solvent resistance differently from a urethane primer composition, the polyester-based primer composition may obtain sufficient adhesive strength between a protection film and a functional coating layer even without assistance from additives such as a cross-linking agent, and may retain stable adhesive strength for a long period of time.

  • Publication number: 20140087149
    Abstract: An aromatic copoly(ester-sulfone) that contains one or more aromatic ester repeating units and one or more aromatic sulfonyl repeating units is provided. While a wide variety of aromatic ester repeating units may be employed, the polymer is nevertheless “low naphthenic” to the extent that it contains a minimal content of repeating units derived from naphthenic hydroxycarboxylic acids and naphthenic dicarboxylic acids. Despite the absence of a high level of conventional naphthenic acid repeating units, the present inventors have discovered that selective control over the type and relative concentration of the aromatic sulfonyl repeating units can lead to “low naphthenic” polymers that are not only soluble in certain solvents, but also capable of exhibiting good mechanical properties. Thus, the ability of the resulting polymer to be dissolved or dispersed in various solvents can be enhanced without sacrificing performance.

    Abstract: A powder that contains microparticles formed from an aromatic polyester is provided. The mean size of the microparticles is generally from about 0.1 to about 40 micrometers. The microparticles may also have a shape that is generally spherical in nature. Regardless of the actual size and shape, however, the size distribution of the microparticles may be consistent throughout the powder. For example, at least about 50% by volume of the microparticles may have a mean size within a range of from about 0.1 to about 200 micrometers. Without intending to be limited by theory, the present inventor believes that a certain size and/or size distribution can improve the quality of coatings formed from the powder.

These adhesives set up rapidly within a well-defined temperature window. The hot-melt adhesives can be used in a variety of applications, but are especially suited as seaming adhesives for roll-applied labels. These adhesives have melting temperatures and crystallization properties that allow their application at temperatures cool enough to prevent curling and premature shrinkage of the shrink label during seaming, and yet produce strong label seams that can withstand the elevated temperatures of a shrink tunnel without sacrificing line speed. Also disclosed are labeled containers and a process for applying a roll-on, shrink label to a container using the hot-melt adhesives of the invention.

The acrylic-modified waterborne alkyd is a hybrid resin prepared by the polymerization of at least one ethylenically unsaturated monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality. The ethylenically unsaturated monomer may also be a latent oxidatively functional (LOF) acrylic monomer. Preparation of the latexes may be achieved by emulsion polymerization of at least one ethylenically unsaturated monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality. Preparation of hybrid latexes which contain latent oxidative functional (LOF) acrylic monomers may also be achieved by emulsion polymerization of at least one LOF acrylic monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality whereby the latent oxidative functionality of the acrylic polymer survives polymerization.

  • Patent number: 6113811
    Abstract: A dichroic polarizing film is made, for example, by, first combining polyvinyl alcohol and a second polymer, such as, polyvinyl pyrrolidone or a sulfonated polyester, in a solvent. The ratio of polyvinyl alcohol to second polymer is between about 5:1 to 100:1 by weight. The film is coated on a substrate, dried, and then stretched to orient at least a portion of the film. The film incorporates a dichroic dye material, such as iodine, to form a dichroic polarizer. This polarizer may be used in conjunction with a multilayer optical film, such as a reflective polarizer, to form an optical polarizer. The multilayer optical film may contain two or more sets of polyester films, where at least one of the sets is birefringent and orientable by stretching. The polyvinyl alcohol/second polymer film and the multilayer optical film may be simultaneously stretched to orient both polymer films.

  • Patent number: 6114439
    Abstract: A crosslinkable aqueous polyester-containing emulsion and a process for preparing the same. The emulsion is obtained by polymerizing unsaturated monomers of acrylic, using a crosslinkable, sulfonated polyester emulsifier having an acid number less than 80 mg KOH/g and an intrinsic viscosity greater than 0.1 dl/g as an emulsifier. The emulsion has the chemical characteristics of both polyester and acrylic resin, i.e. has low volatile organic compounds, good mechanical stability, and good storage stability. Since the emulsion is crosslinkable, a film formed by the emulsion has excellent adhesion, water and heat resistance. Thus, the emulsion is useful for coating and printing on Nylon, PET, OPP films, as well as for high performance industrial surface coating and adhesion for which good heat-, water-, and weather-resistance are required.

  • Patent number: 5913972
    Abstract: An aqueous pigment dispersion is formed of a pigment, an aqueous medium and a dispersant resin. The dispersant resin contains a hydrophobic moiety and a hydrophilic moiety in its molecule. The hydrophobic moiety is a polyester linkage chain formed of ester linkages as primary linkages. The hydrophilic moiety is a water-soluble resin containing sulfonic groups or their salts. The water-soluble resin can be produced, for example, by reacting a polyol with maleic acid and/or fumaric acid to synthesize an unsaturated polyester resin and then adding acid sulfurous acid or its salt to the unsaturated polyester resin to form groups represented by the following formula (I): ##STR1## wherein M.sup.1 represents a hydrogen atom, an alkali metal, an ammonium group or a lower aliphatic quaternary ammonium group. The aqueous pigment dispersion is useful as a water-based ink for writing or recording equipments such as writing instruments, printers, copying machines, fax machines and printing machines.
