じさせない形で実装が行なえる。<Prior art> The conventional method for replicating and mounting holograms is to perform emboss molding on a resin layer coated on a substrate using a stand bar on which a surface relief type hologram is formed.
A surface relief type hologram is formed on the resin, aluminum is vapor-deposited on the surface, a heat-sensitive adhesive is applied, and a hot stamp is used to transfer the hologram onto the object to be transferred, and a hologram transfer foil is used for this. This method does not rely on optical methods but mechanically replicates holograms, making it suitable for mass production at low cost.As it is a transfer method different from the sticker format6, it is possible to reproduce the hologram in a form that hardly makes you feel the thickness of the hologram. Can be implemented.

った。<Problems to be solved by the invention> With hologram transfer foil, the hologram is embossed in the first step, and then transferred by hot stamping in the second step, so the base material and resin at the time of embossing are However, contradictory performances are required, such as adhesion to the film and removability during transfer. With conventional transfer foils, embossing is possible, but the transferability is extremely poor, and while the peelability during transfer is good, the resin easily peels off from the base material during embossing and has problems such as adhesion to the stand bar. there were. Furthermore, among transfer foils that can be used for both embossing and transfer, there are some that have increased heat resistance of the resin, resulting in poor moldability of holograms and dark reproduced images. Because hot stamping is performed, there is a limit to the thickness of the base material, and it is necessary to use a thin base material of about 20 am to 50 μm.There is a problem that press unevenness tends to occur during embossing molding, and the quality of the appearance deteriorates. was there.

グラム転写箔が得られることを見出したものである。That is, the present invention provides a transfer foil in which a resin layer with a relief hologram formed on the surface, a metal reflective layer by vapor deposition, and a heat-sensitive adhesive layer are sequentially stacked on one side of a support film, in which the resin layer is a polyether polyol, It is composed of a two-component reactive urethane resin that uses a polyol component consisting of polyester polyol and acrylic polyol as the main ingredient and a prepolymer component with incyanate groups as a curing agent, so it has excellent moldability and transferability during embossing. It has been discovered that a hologram transfer foil can be obtained.

Support film (for 11, resins such as polyester resin, polycarbonate resin, and cellophane can be used, but polyester resin is most suitable due to its characteristics such as heat resistance, processability, and uniformity.
A film of about 100mm can be used. The resin layer (2) has a film thickness of about 5 μm from 0 to 5, which is obtained by coating and drying a resin in the form of a paint on one side of the support film (1) by a method such as roll coating or blade coating. , has moderate adhesion to the support film (1), has excellent formability by heating and pressurizing during embossing molding, and does not adhere to the stand bar whose surface is plated with nickel, gold, chrome, etc. Furthermore, it has good adhesion to the metal reflective layer (3). The metal reflective layer (3) is preferably a metal with high surface reflectance, such as aluminum crumb, gold, silver,
Tin etc. and alloys containing the above metals can be used,
Further, as a method of forming a metal thin film using the above-mentioned materials, known methods such as vacuum evaporation, sputtering, ion blasting, etc. are used, and the thickness is 100 mm.

ポリオール硬化型ポリウレタン塗料などがある。A feature of the present invention is that a two-component reactive urethane resin is applied as the resin layer (2), and urethane paints are generally made from oil-modified polyurethane obtained by reacting a drying oil derivative with diisocyanates. Paints are prepolymers obtained from various polyols and diisocyanates, and are moisture-curing polyurethane paints that harden due to moisture in the air. Polyisocyanate prepolymers are capped with volatile active hydrogen compounds such as phenol and mixed with polyols. Liquid-type paints include block-type urethane resin paints that react with polyols by heating at high temperatures, and catalytic curing types that react prepolymers with free incyanate groups with catalysts and accelerators such as tertiary amines and organic tin salts. There are also polyurethane paints and polyol-curable polyurethane paints that are composed of two components: a polyol component and a prepolymer component having free isocyanate groups.

樹脂にブレンドすることは有効である。In the present invention, a polyol-curable polyurethane resin consisting of a polyol component such as polyether polyol, polyester polyol, or acrylic polyol and a prepolymer having an isocyanate group is used because of its physical properties such as solvent resistance, heat resistance, and processability. However, paint suitability,
From the viewpoint of embossability, peelability from the support film, etc.
The polyol component has T and G of 70°C to 105°C,
A two-component reactive urethane resin made of an acrylic polyol and having an OH value of 50 to 150 is most suitable. Furthermore, as an agent to improve coating suitability and adjust transferability, cellulose resins such as nitrocellulose, acetylcellulose, cellulose acetate butyrate, cellulose acetate propionate, ethylcellulose, and methylcellulose are added to urethane resin in a range of up to 30%.

割。In addition, it has excellent adhesion with the metal reflective layer (3), good peeling from the support film (1), and good peeling of the film, so the metal reflective layer (3) has poor peeling during hot stamping. It enables reliable transfer without defects such as transfer unevenness, flaking, or blistering. Furthermore, the excellent heat resistance of urethane resin prevents cracking, whitening, and shrinkage caused by heat during the vapor deposition process and hot stamping. It was possible to prevent deterioration in appearance quality such as destruction of the hologram pattern. In addition, whitening and cracking occur due to attack of the resin layer (2) by the solvent used when forming the heat-sensitive adhesive layer (4).
