The present invention relates to a method comprising the steps of applying to a paper or paperboard substrate an aqueous dispersion of polymer particles which comprise structural units of a vinyl ester, vinyl alcohol, and an acrylate monomer, then drying the composition. The method provides a coating that has oil and grease resistance, mineral oil barrier performance, and beat scalability.

Process for preparing a coated paper article

The present invention relates to a coated paper article with an intermediate basecoat layer comprising high void fraction porous hollow sphere polymer particles (HISPs). HSPs with very small pore area density and high void fraction result in increased optical density at a given print energy in thermal printing applications.

Thermosensitive paper

A recording material including a support having at least one colored surface and a layer of polymeric material is described. The layer including polymeric particles has a core/shell structure, and the particles are either (i) particles having an outermost polymer shell having a calculated Tg of from 40° C. to 80° C., or (ii) particles having an inner polymer shell having a calculated Tg of from 40° C. to 130° C. and an outer polymer shell having a calculated Tg of from −55° C. to 50° C. The calculated Tg of said outer polymer shell is lower than that of said inner polymer shell, the particles including, when dry, at least one void capable of providing opacity to said layer, and the colored surface has sufficient color density to be visibly contrasting to a surface of the subsequent layer including the polymeric particles disposed thereon.

Recording material

The present invention relates to a coating composition comprising an aqueous dispersion of a binder and first and second core-shell polymer particles having aqueous neutralized acid cores, wherein the dry bulk density of the first core-shell polymer particles is in the range of 0.25 to 0.5 g/mL; and the dry bulk density of the second core-shell polymer particles is in the range of 0.30 to 0.90 g/mL. The composition of the present invention is useful as an undercoat layer for a thermosensitive recording material.

Paper coating composition

The present invention relates to a thermally printable paper article with an elastomeric underlayer, which imparts improved printing performance.

Thermally printable paper article with elastic interspersing layer

The present invention relates to a thermosensitive recording material comprising paper, an undercoat layer disposed on the paper, and a thermosensitive recording layer disposed on the undercoat layer, wherein the undercoat layer comprises a binder and first and second hollow sphere polymer particles, wherein the first hollow sphere polymer particles have a diameter in the range of from 1.2 &#x3bc;m to 1.8 &#x3bc;m; the second hollow sphere polymer particles have a diameter in the range of from 0.25 &#x3bc;m to 1.0 &#x3bc;m; the number ratio of the second to the first hollow sphere polymer particles is in the range of from 1:1 to 20:1; the diameter of the second hollow sphere polymer particles is in the range of from 15 to 65% of the diameter of the first hollow sphere polymer particles; the dry bulk density of the first hollow sphere polymer particles is in the range of 0.25 to 0.5 g/mL; and the dry bulk density of the second hollow sphere polymer particles is in the range of 0.30 to 0.90 g/mL.

Thermosensitive recording material

The present invention relates to composite polymeric particles for use as infrared reflectors in optical bandpass applications.

Composite particles for optical bandpass filters

A recording material including a support and disposed thereon at least one layer including certain core/shell polymeric particles, the particles having, whey dry, at least one void; and an opacity reducer is provided. A method for providing an image using the recording sheet is also provided.

A fuel cell, having improved sealing against leakage, includes a sealant disposed over the peripheral portions a membrane electrode assembly such that the cured sealant penetrates a gas diffusion layer of the membrane electrode assembly. The sealant is applied through liquid injection molding techniques to form cured sealant composition at the peripheral potions of the membrane electrode assembly. The sealant may be thermally cured at low temperatures, for example 130&#xb0; C. or less, or may be cured at room temperature through the application of actinic radiation.

Sealant integrated fuel cell components and methods and systems for producing the same

A fuel cell, having improved sealing against leakage, includes a fuel cell component having a cured sealant, wherein the cured sealant includes a telechelic-functional polyisobutylene, an organhydrogenosilane crosslinker, a platinum catalyst and a photoinitiator. The fuel cell component may be a cathode flow field plate, an anode flow field plate, a resin frame, a gas diffusion layer, an anode catalyst layer, a cathode catalyst layer, a membrane electrolyte, a membrane-electrode-assembly frame, and combinations thereof. A method for forming such a fuel cell includes the steps of providing a fuel cell component including a substrate; providing a mold having a cavity; positioning the mold so that the cavity is in fluid communication with the substrate; applying a curable liquid sealant composition into the cavity, wherein the curable sealant composition includes a telechelic-functional polyisobutylene, an organhydrogenosilane crosslinker, a platinum catalyst and a photoinitiator; and curing the composition with actinic radiation.
