Abstract:
The present invention provides a method of easily planarizing the uneven surface of a substrate having an uneven surface. This method comprises the steps of forming a coating film containing spherical fine particles on a surface of a smooth substrate; sticking the surface of the smooth substrate provided with the coating film containing spherical fine particles to the uneven surface of a substrate having an uneven surface; and transferring the coating film containing spherical fine particles to the uneven surface of the substrate so that the uneven surface is planarized.
Abstract:
After a thin liquid agent film is formed by supplying a liquid agent onto a plate-like developer holder, this liquid agent film and the surface of a substrate are opposed. The liquid agent film and the substrate are brought into contact with each other at a point by declining the substrate and moving it close to the liquid agent film, or by curving the substrate toward the liquid agent film. Then, the substrate is made parallel to the liquid agent film, and the liquid agent is supplied such that the contact area of the liquid agent film spreads over the entire surface by the interfacial tension between the liquid agent film and the substrate. Since a thin liquid agent film can be uniformly formed below the substrate, processing can be performed with a small consumption amount. Additionally, the liquid agent can be supplied to the substrate without holding air.
Abstract:
A method and apparatus for applying pressure sensitive adhesive to a substrate, in which the adhesive is deposited on a transfer surface, such as a circulating transfer belt, dried, and subsequently transferred to a plurality of overlapping sheets. The sheets are preferably coated with a primer or a low adhesion backsize, or both, prior to application of the adhesive.
Abstract:
A laminating method for objects such as important documents, old documents and other printed matters to prevent a forgery or quality degradation of those objects or to protect the surfaces of those objects. In the lamination method, a released paper sheet, released synthetic resin film or non-released synthetic resin film is laminated using a thermoplastic resin solution, thereby forming a lamination sheet as a medium, so that the resultant synthetic resin thin film on the lamination sheet is subsequently transferred onto an object as the lamination sheet passes through a nip defined between pressing rollers along with the object.
Abstract:
A color-shifting paint comprising a polymeric paint medium and a plurality of colored interference thin film platelets dispersed in the paint medium. Each platelet being characterized in that platelets has first and second generally planar outer surfaces and an edge thickness perpendicular to the first and second generally planar outer surfaces. Each platelet is comprised of a metal reflecting layer having first and second surfaces. A multilayer interference structure is disposed on each of the first and second surfaces of the metal reflecting layer to provide a symmetrical platelet. The multilayer interference thin film structure comprises a pair of layer consisting of a dielectric layer formed of a dielectric material and a semi-opaque layer. with the dielectric layer directly adjacent to the metal reflecting layer. The thickness of the dielectric layer determines the color and the dielectric material determines the degree of color shift. The platelets have an aspect ratio of at least 2:1 for the longest planar dimension of the first and second outer surfaces in comparison to the edge thickness of the platelets, and have a maximum dimension on any of said surfaces ranging from 2-200 microns.

Abstract:
A process for the selective metallization of a substrate and the product formed thereby. An extremely thin (substantially less than the wavelength of light) coat of metallic particles is deposited on a transfer agent. A thin coat of varnish is selectively applied to either the substrate or the transfer agent, the substrate and the transfer agent are laminated together and the varnish is cured. The metallic particles will become absorbed within the varnish and the substrate and transfer agent are then separated. The substrate is provided with a highly polished specular metallic finish in predetermined areas.

Abstract:
Articles and methods for forming optically variable thin film flakes and replicated coatings having preselected optical properties. The articles generally comprise a flexible web of material and an optically variable thin film coating formed on one surface of the web. The optically variable coating is separated from the web to form optically variable thin film flakes. The flakes are disposed in ink and paint vehicles to provide optically variable inks, paints and the like.
