Abstract: A hot-stamping foil has a carrier that is a base film or a coated base film, and a laminated optical decoration formed on the carrier in a removable manner. The laminated optical decoration includes a laminated optical structure, an anchor layer formed on the laminated optical structure at a side opposite against the carrier, the anchor layer being a mixture of an acid-modified polyolefin and a vinyl chloride-vinyl acetate copolymer, and an adhesive layer which is formed on the anchor layer at a side opposite against the laminated optical structure. The adhesive layer has an adhesive domain containing an acid-modified polyolefin as a major component, and a non-adhesive domain containing a blocking preventing agent as a major component. The blocking preventing agent is one or both of a resin filler and an inorganic filler. A glass transition point of the blocking preventing agent is greater than 60° C.

Abstract: A method and an apparatus for producing a relief-pattern forming, the method and apparatus being suitable for producing a film-like material, such as an embossed film, having a fine relief-structure pattern formed on a surface thereof so as to have a distinctive optical effect with higher quality, good productivity, and fewer defects. A transfer pattern printed layer having an inverted structure of a relief-structure pattern is formed on a second substrate by printing a transfer pattern onto the surface of a first substrate on which the relief-structure pattern is formed at a predetermined position by registration with the relief-structure pattern followed by drying, laminating with the second substrate, curing and peeling.

Abstract: A laminate includes a recording layer, a translucent front covering layer and a security foil laminated between the recording layer and the front covering layer and sealed in the laminate. The security foil has a thickness that is ⅕ or less the thickness of the recording layer to prevent or reduce falsification reusing the security foil. The security foil includes a relief layer having a relief surface and a protective layer covering the relief surface. In the thickness direction of the laminate, the protective layer adheres to the recording layer and the relief layer adheres to the front covering layer. The adhesion strength between the security foil and the recording layer is higher than the adhesion strength between the security foil and the front covering layer.

Abstract: A catalyst layer for polymer electrolyte fuel cells that improves drainage or gas diffusion, reduces or prevents the occurrence of cracking in a catalyst layer, enhances catalyst utilization efficiency, exerts high output power and high energy conversion efficiency, and has high durability, and also provides a membrane-electrode assembly and a polymer electrolyte fuel cell using the catalyst layer. The catalyst layer for polymer electrolyte fuel cells contains a catalyst, carbon particles, a polymer electrolyte, and a fibrous material. In the catalyst layer, the carbon particles carry the catalyst1. The catalyst layer for polymer electrolyte fuel cells has voids. The percentage of frequencies of the voids having a cross-sectional area of 10,000 nm2 or more is 13% or more and 20% or less among the voids observed in a thickness-direction cross section of the catalyst layer for polymer electrolyte fuel cells perpendicular to the surface thereof.
