A method for manufacturing a sheet laminate to be affixed to an adherent surface of an object, the method comprising preparing a sheet member having a front surface to become a design surface and a rear surface on which an adhesive part has been formed, bending an edge part of the sheet member by sandwiching the sheet member from a front surface side and a rear surface side in a mold, and heating a part of a bent sheet member. The sheet laminate has a flat part spreading out in a flat plate shape, a side surface on which the edge part bent by the bending step is configured, and a connecting surface protruding and curving toward the front surface side between the flat part and the side surface, and in the heating step, the connecting surface is partially heated after the side surface is molded in the bending step.

Method for manufacturing sheet laminate

A decorative laminated sheet with excellent scratch resistance that is capable of adhering to a polyolefin-based resin substrate, and that is a hardly adhesive material, through an extrusion method, a vacuum-pressure molding method, a mold integrated injection molding method, and the like. The decorative laminated sheet includes a surface layer, a design layer, and an adhesive layer containing a polymer having a propylene unit of 85 mass % or more, in that order.

Disclosed herein are improved thermoplastic polyurethane compositions, articles, and related methods. These compositions include aliphatic thermoplastic polyurethanes having a hard segment content ranging from 57 percent to 80 percent by weight. The hard coat compositions have a Shore D hardness of at least 70 and can display an Elongation at Break test result at 25 degrees Celsius of at least 150 percent. These materials, when hardened, can serve decorative and/or protective functions while displaying both a high degree of elongation at moderate temperatures and high hardness.

Thermoplastic polyurethane compositions, articles, and methods thereof

The disclosed retroreflective sheet contains a retroreflective layer and a polyurethane surface protecting layer, wherein the surface protecting layer contains at least a reaction product of a polyol with either a polyester backbone or a polycarbonate backbone and a trifunctional or higher aliphatic isocyanate, and the glass transition temperature Tg of the surface protecting layer is 50&#xb0; C. or higher, and the tan &#x3b4; of the loss tangent at 120&#xb0; C. is 0.1 or less.

Retroreflective sheet, license plate, and manufacturing method thereof

A structure comprising a decorative sheet having a surface layer and an adhesive layer containing a polymer having 25 to 100 mass % of propylene units, and a substrate containing a polymer having 25 to 100 mass % of propylene units. The decorative sheet and the substrate are integrated by vacuum-pressure forming or vacuum forming.

Structure integrated by vacuum-pressure forming or vacuum forming, and manufacturing method thereof

In a decorative sheet including a surface layer and an adhesion layer, the surface layer is a polyurethane layer obtained by crosslinking using a curing agent and coating and drying of a straight chain polyurethane resin having a specified molecular weight and acid value, the polyurethane resin being obtained by reaction of a diamine chain extender agent with a polyurethane prepolymer obtained by reaction of a polycarbonate diol having an alicyclic structure, an aliphatic diol having a carboxyl group, and 4,4'-cyclohexylmethandiisocyanate.

Decorative sheet containing a polyurethane layer and structure

A decorative article capable of being used in combination with an article having a light source and of remarkably improving the decorative effect together with the light source. The decorative article is attached to an article having a light source, and comprises, at least, an appearance-providing layer defining an appearance of the decorative article, and a light-storage layer which is disposed under the appearance-providing layer and is able to store the light from the light source and generate afterglow.

Decorative article and vehicular lamp

A decorative article () capable of being used in combination with an article having a light source () and of remarkably improving the decorative effect together with the light source. The decorative article () is attached to an article having a light source (), and comprises, at least, an appearance-providing layer () defining an appearance of the decorative article, and a light-storage layer () which is disposed under the appearance-providing layer () and is able to store the light from the light source () and generate afterglow.

A vehicle lamp includes a lamp chamber containing at least one light source in an interior thereof and having a light-emitting opening, a lamp cover is attached to the light-emitting opening, and a polarizing film is applied to an inner surface of said cover body. The lamp cover includes a transparent cover body having a configuration and size capable of covering at least a light emission surface of the lamp. The polarizing film has fine textured structures on a surface thereof for changing color of the exterior of the lamp when the lamp is in a lit condition compared to an unlit condition.

Automotive lamp

An automotive lamp having an excellent outer design along with a simple structure and easy production. The automotive lamp can comprise a light source (), a housing (), a light-emitting opening and a light-transmissive lamp cover (), in which a non-light-emitting area of the lamp cover, which does not substantially concern the emission of the light generated from the light source (), is provided with a light transmissive colored member () through which, under unlit conditions, outer light is transmitted to the housing (), to thereby reflect the transmitted light at the inner wall of the housing () and emit the colored and reflected light out of the housing ().

Automotive lamp with light transmissive colored member

A stainless steel article which has a transparent and uniform resin coating thereon, which can utilize the surface appearance of the stainless steel used as a substrate, which shows a high adhesive strength between the resin coating and stainless steel as a ground, which can be easily produced with a small number of steps, and which is particularly useful as an automotive exterior article. The stainless steel article comprises a stainless steel substrate and a transparent resin film with which at least one surface of the substrate is coated, the resin film comprising a transparent synthetic resin base and a transparent heat-sensitive adhesive layer formed on the synthetic resin base on the side of the stainless steel substrate, and the resin film being bonded to the stainless steel substrate through a silane coupling agent.
