An article comprising a microstructured surface, wherein the microstructures compris the reaction product of a of a polymerizable composition comprising at least one oligomer or monomer that comprises at least two (meth)acrylate groups and at least one monofunctional (meth)acryl monomer and the reaction product has a glass transition temperature of less than 35&#xb0; C.

Microstructured article comprising a polymerized composition having low glass transition temperature

A method of forming microstructures on a substrate is disclosed. A microstructured assembly that may be used in the method for forming microstructures on a substrate is also disclosed. The methods and assemblies of the present disclosure can reduce the amount of air entrapped in barrier ribs formed on substrates used in Plasma Display devices.

Method of forming microstructures on a substrate and a microstructured assembly used for same

A method of producing a substrate () for a plasma display panel, which comprises the steps of: contacting a rib precursor composition () containing a first photo-setting initiator having a first absorption edge and a first photo-setting component, closely with a base (); filling a mold (30), obtained by photo-setting of a second photo-setting component in a presence of a second photo-setting initiator having a second absorption edge whose wavelength is shorter than that corresponding to the first absorption edge of the first photo-setting initiator, with the rib precursor composition (); irradiating the rib precursor composition () with light having a wavelength longer than that corresponding to the second absorption edge to set the rib precursor composition (), thereby forming a rib () on the base (); and removing the mold () from the resulting base () on which the rib () is formed.

Barrier rib formation on substrate for plasma display panels and mold therefor

A method of producing barrier ribs for a plasma display panel substrate, which comprises the steps of: (a) partially filling a groove portion of a mold with a first photosensitive glass-ceramic paste selected from a photosensitive black glass-ceramic paste and a photosensitive white glass-ceramic paste, and curing the paste by irradiating with radiation; (b) supplying a second photosensitive glass-ceramic paste, which is different from the first photosensitive glass-ceramic paste, selected from the photosensitive black glass-ceramic paste and the photosensitive white glass-ceramic paste, on a glass base, and laminating the mold with the glass base through the second paste to form a laminate; (c) irradiating the laminate with radiation to form a rib precursor molded article composed of two white and black layers; (d) removing the mold from the glass base and the rib precursor molded article to transfer the rib precursor molded article to the glass base; and (e) sintering the rib precursor molded article to form a rib formed integrally on the glass base.

Method of producing barrier ribs for plasma display panel substrates

An apparatus is provided for producing a substrate for PDP, which can easily reduce ununiformity of a dielectric layer and defects of ribs. The apparatus is so constituted that it comprises: a table for the plate, a rib precursor supplying portion for providing a precusor of the ribs on the plate, a pliable mold having at least groove portions provided in parallel with each other at a fixed distance, which is disposed on the precursor of the ribs provided on the plate, a mold pressing portion for applying a pressure to the mold, thereby to contact the mold closely with the plate via the precursor of the ribs, and a driving portion for moving the mold pressing portion along the groove portions of the mold.

Apparatus, mold and method for producing substrate for plasma display panel

A molding composition is provided that includes an inorganic component, an organic binder component, and a debinding catalyst. The molding composition is capable of lowering the sintering temperature, for example, when the molding composition is used to make ceramic microstructures such as barrier ribs for plasma display panels.
