A print media for water-based ink comprising a base, and an ink reception layer with a surface not facing the base to be used as the printing surface provided on one side of the base, wherein the ink reception layer includes; a hydrophilic first resin and a second resin having a thermal adhesive property a micro-phase separation structure in the printing surface, which is formed by the first resin and the second resin; and the second resin contains an acrylic polymer with a quaternized amino group.
Abstract:
A stretchable tape flag, wherein a backing layer has a stretchable portion capable of being stretched by hand and has elastic and plastic deformation characteristics on at least one portion; an adhesive layer capable of reapplication and placed on at least part of one side of the backing layer; and stuck on the object with the stretchable portion of the backing layer extended.
Abstract:
A hybrid sound absorbing sheet, comprising a microperforated film and a perforated metal foil disposed on the microperforated film, is provided. Also provided is a hybrid sound absorbing sheet comprising a microperforated film and a perforated metal foil disposed on the microperforated film, wherein the perforated metal foil is embossed.
Abstract:
A sound absorbing board that is a sound absorbing board where a decorative layer and a rigid substrate material are laminated, and where the substrate material contains parallel grooves spaced at a pre-determined distance, and also, where the cross sectional surface of the grooves in a direction perpendicular to the longitudinal direction of the substrate has a shape that contains mutually adjacent neck parts and trunk parts is described. The sound absorbing board has decorative properties and at the same time has sound absorbing, sound isolation properties, and can be easily processed.
Abstract:
To provide a multifunctional mask filter unit that can realize both suppression of pressure loss and improvement of filtering efficiency, a filter unit is provided with a charged filter that has a base layer made from one or more sheet layers and an additional function layer. Each sheet layer is provided with a base and a plurality of solid protrusions that extends from a surface of the base, the protrusions having a stem portion that has a root-side side surface and a tip-side side surface. With a first angle (angle formed between the base of the sheet layer and the root-side side surface of the stem portion of the sheet layer) and a second angle (angle formed between the tip-side side surface of the stem portion of the sheet layer and the base of another sheet layer adjacent to the stem portion and/or angle formed between the tip-side side surface of the stem portion of the sheet layer and the base of an additional function layer adjacent to the stem portion), one is 90° or more and less than 180° and the other is 45° or more and less than 180°.
Abstract:
An anti-slip sheet to be used around water can be easily fixed onto the floor or bathtubs, etc., by simply adhering. The sheet resists curling (coiling) or separation, has low surface irritation on skin, and even under humid environment has excellent anti-slip properties. The anti-slip sheet includes a resin film having a Shore A hardness of 60 or higher and 82 or lower, a protrusion and indentation surface where the maximum value of the adjacent protrusions peaks are within the range of 10 microns or higher and 150 microns or lower, has a maximum height Rmax of the surface roughness within the range of 15 microns or higher and 90 microns or lower, and includes a top part reinforcing film positioned on the resin film on the side opposite to the protrusions and indentations containing surface which is harder than the resin film, and includes a bottom part adhesive layer positioned on the side of the top part reinforcing film that is opposite to the resin film.
Abstract:
A multilayer sound absorbing structure, comprising a first microperforated film, a mesh layer and a second microperforated film disposed in this order is provided.
Abstract:
The charged filter is provided with a first layer and a second layer. The first layer is provided with a base and a plurality of solid protrusions that extends from a surface of the base and is adjacent to the second layer, the protrusions having a stem portion that has a root-side side surface and a tip-side side surface. A first angle, which is one angle from among an angle formed between the root-side side surface of the stem portion and the base of the first layer and an angle formed between the tip-side side surface of the stem portion and the base of the second layer, is 90° or more and less than 180° and a second angle, which is the other angle among these, is 45° or more and less than 180°.
