Abstract:
A method of making a display assembly includes the steps of (a) attaching a first substrate and a second substrate with an optically clear heat activated adhesive to form a laminate. Each of the first and second substrate has opposing major surfaces. At least one of the first and second substrate has a three dimensional surface topography covering at least a portion of one of its major surfaces or is distortion sensitive. At a heat activation temperature, the adhesive is pressure sensitive. The method also includes heating the laminate to the heat activation temperature of the adhesive causing the adhesive to flow. The activation temperature is greater than 40°C and less than 120°C.
Abstract:
A micro-structured optically clear adhesive, including a first major surface and a second major surface, wherein at least one of the first and second major surfaces comprises a micro- structured surface of interconnected micro-structures in at least one of the planar dimensions (x-y), is disclosed. The micro-structured optically clear adhesive has a tan delta value of at least about 0.3 at a lamination temperature and is non-crosslinked or lightly crosslinked. The micro- structured surface may include indentations having a depth of between about 5 and about 80 microns. A method of laminating a first substrate and a second substrate without the use of a vacuum is provided. The method includes providing a micro-structured optically clear adhesive, removing a release liner from a first side of the micro-structured optically clear adhesive, contacting the first side of the micro-structured optically clear adhesive with a surface of the first substrate, removing a micro-structured release liner from a second side of the micro-structured optically clear adhesive to expose a micro-structured surface, and contacting the micro- structured surface with a surface of the second substrate.
Abstract:
A method for manufacturing an image display device includes: providing an image display unit having an image display surface; providing a translucent protective material having a light-shielding portion; disposing a liquid optically clear adhesive (LOCA) between the image display surface of the image display unit and the translucent protective material; and curing the LOCA to adhere the image display unit with the translucent protective material. The LOCA is a two-part redox-type adhesive composed of a first composition including a first base agent containing a compound having at least one ethylenically unsaturated group and a polymerization initiator and a second composition including a second base agent containing a compound having at least one ethylenically unsaturated group and a reducing agent capable of decomposing the polymerization initiator.

Abstract:
A microlens sheet that can be used as a floating image material is provided having a microlens array layer that can be produced by a more simple replication process, without requiring adjustment of the thickness. The microlens sheet has high scratch resistance and dust resistance. The microlens sheet has a microlens array layer including a first surface, and a second surface formed by replication, having a plurality of arranged convex lenses and one or more partition walls with a fixed height (Hw) that protrudes past the top of the convex lenses, a radiation sensitive layer which is disposed substantially at a focal position of the convex lenses on a side of the microlens array layer opposite the first surface, and which is substantially parallel to the second surface.
Abstract:
The present disclosure provides a microlens laminate having a protected surface and exhibiting excellent appearance. The microlens laminate is capable of providing a composite image that floats above, in the plane of, and/or below the laminate. The microlens laminate includes (a) a microlens sheeting comprising a microlens layer composed of a plurality of microlenses, the microlens layer having first and second sides, and a light-sensitive material layer disposed adjacent the first side of the microlens layer; and (b) a transparent material layer disposed at the second side of the microlens layer in the microlens sheeting.
Abstract:
A rustproofing agent for a zinc plated steel sheet is provided which contains (A) a chromium aqueous solution containing an organic substance and (B) an acid metal such as a metal salt of nitric acid or phosphoric acid. All of the chromium in the chromium aqueous solution of component. A is trivalent chromium. It is preferable if the organic substance in component A contains at least one type of oxy acid or oxide thereof. The metal in the acid metal salt of component B is an alkaline earth metal, cobalt, nickel, iron, zirconium, titanium, etc. It is also preferable if (C) a water-dispersible silica is contained as an additional component. The present invention also provides a zinc plated steel sheet, in which at least one side of the surface of a zinc plated steel sheet is coated with the zinc plated steel sheet rustproofing agent and the rustproofing agent dried to form a coating with a dry coating weight of 0.01 to 3 g/m .
