Abstract:
Provided is a workpiece bonding method that makes it possible to achieve a joining state with a high strength and to obtain a good repeatability of the joining state. A workpiece bonding method according to the present invention is a workpiece bonding method for bonding two workpieces to each other, each of the two workpieces being composed of a material selected from the group consisting of synthetic resin, glass, silicon wafer, crystal and sapphire, the workpiece bonding method including: a surface activation step of activating a bonded surface of at least one of the workpieces; and a laminating step of laminating the two workpieces such that respective bonded surfaces contact with each other, and a pretreatment step of removing moisture from the bonded surface of the workpiece that is to be subjected to the surface activation step is performed before the surface activation step is performed.
Abstract:
The present application relates to methods of manufacturing a laminate comprising coating at least a portion of at least a first substrate with a last down energy-curable adhesive ink; applying at least a second substrate to the coated portion of the first substrate to form a laminate; and curing the laminate. The present application further relates to adhesive ink compositions comprising at least one acrylate monomer, at least one pigment, at least one wetting agent, and at least one dispersing agent.
Abstract:
A water-based ink and a method to form a digital print with the water-based ink on a dense substrate including a polymer material or on surfaces that are heated and pressed after printing. The substrate is prior to the printing step preferably heated in order to prevent floating of the water-based ink drops.
Abstract:
A simplified switchable object and methods of making same are provided. The methods may include steps of applying a switchable material on a first surface of a first substrate, the switchable material having a thickness and a shape; applying a barrier material on the first substrate, circumferential to the switchable material; and applying a second substrate over top of, and in contact with, the switchable material and the barrier material, the first substrate, second substrate and barrier material defining a closed chamber encapsulating the switchable material. The methods may further include a step of applying a seal material.
Abstract:

The method for producing a birefringent lens for a stereoscopic image display of the present invention has good productivity.
Abstract:
There is provided a polyimide layered product with a support which has a smooth surface to enable a sophisticated device to be formed thereon and in which the layered polyimide does not peel off even in a high-temperature process on device formation, and furthermore, the polyimide layered product can be peeled off easily from the support after the device is formed on the polyimide layered product. By preparing a polyimide film with a face at the support side and subjected to a surface treatment; subjecting at least one of a face of the support and the face of the polyimide film which are opposite to each other to a patterning treatment using a coupling agent to form a satisfactorily bondable part and an easily releasable part which differ in adhesion/peel strength; subsequently, superposing the support and the polyimide film to be subjected to a pressurizing/heating treatment and to be bonded to each other; subjecting the surface of the polyimide film to an organic alkali treatment; and then, applying a polyamic acid solution free from a slip agent ingredient, drying the coating film and imidizing the film, a layered product having a structure of at least three layers in which at least one layer contains a slip agent material and both surface layers have no slip agent material is produced.
Abstract:
The present invention discloses a transparent adhesive sheet for optics, which is capable of satisfying both adhesion and rework property, in view of the above problems of prior art. A production method of a silicone-based transparent adhesive sheet for optics for assembling the optical components, characterized by forming a surface activation treated surface, in which peel strength after laminating onto an adherend increases with time, as compared with peel strength before lamination, by performing surface activation treatment using UV-ray irradiation on at least a part or the entire surface of an adhesive face contacting with the adherend of said transparent adhesive sheet for optics, and a transparent adhesive sheet for optics obtained from the production method thereof, and the like.
