[0003] In particular, there have been the following two methods for forming hairlines on automobile interior parts and automobile exterior parts. (2) A method of forming a flaw of a hairline on a metal plate constituting each part by cutting or the like. (3) A transfer material in which a hairline is formed on a release surface of a base sheet having release properties by cutting or the like, and only a printing layer is provided on the base sheet is sandwiched in a molding die, and a resin is filled in the cavity. A method in which a resin material is obtained by injection-filling, a transfer material is adhered to the surface of the resin material at the same time as the resin material is obtained, the base sheet is peeled off, and only the printed layer on which the hairline is copied is formed on the resin product.

[0004]

However, in (1),
Although the release layer was provided on the metal vapor deposition layer, the metal vapor deposition layer was easily discolored by sun light, reflected light, or the like, damaged by friction, or easily affected by oil or the like of human hands. In order to eliminate such a problem, clear coating with a hard transparent resin may be considered on the release layer. However, in this case, the coating cost is increased, the number of steps is increased, and the productivity is reduced. (2) has the following problem.
Since the metal plate is inferior in elasticity to the resin molded product, it is difficult to fit the metal plate to other metal parts such as wheels. Further, since the metal plate is heavier than the resin molded product, the workability at the time of fitting to a metal part such as a wheel is poor. Further, since the metal plate is bare metal, it is necessary to apply a coating for corrosion prevention, which is costly. In addition, since the metal plate has a hard surface, it is difficult to directly form a so-called delicate hairline having fine irregularities. In (3),
Since the printed layer on which the hair lines are formed is not protected by the protective layer, the hair lines are easily crushed by friction or the like, and the appearance design is impaired. Clear coating with a hard transparent resin in order to make the hairline eyes hard to be crushed increases the painting cost, and the fine irregularities are completely filled with the transparent resin, and the delicate hairline eyes are erased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic sectional view showing an embodiment of a light-resistant metal vapor deposition transfer material according to the present invention. FIG. 2 is a schematic sectional view showing one embodiment of a light-resistant metal vapor-deposited molded product according to the present invention.

First, the metal-deposited transfer material 1 having light resistance according to the present invention will be described.

A metal deposition transfer material 1 shown as an example in FIG.
A light-resistant protective print layer 3 containing an ultraviolet absorber and an active energy ray-curable resin composition is provided on a release surface of a base sheet 2 having a release property, and at least a metal is provided on the protective print layer 3. A light-resistant metal vapor-deposited transfer material 1 provided with another layer having a vapor-deposited layer 6, the metal vapor-deposited transfer material 1 is sandwiched in a molding die, and a resin is injected and filled in the cavity. After the transfer material is adhered to the surface of the resin molded article at the same time as the resin molded article is obtained, the resin sheet is used in a method for producing a metal vapor-deposited molded article through a step of peeling the base sheet 2 and a step of irradiating with active energy rays. The hairline 9 is formed on the release surface. Hereinafter, a description will be given of an example in which the pattern printing layer 4, the front anchor layer 5, the metal deposition layer 6, the rear anchor layer 7, and the adhesive printing layer 8 are sequentially laminated as the other layers.

The base sheet 2 having releasability includes resin sheets of polypropylene resin, polyethylene resin, polyamide resin, polyester resin, polyacrylic resin, polyvinyl chloride resin, etc., aluminum foil,
Metallic foils such as copper foils, glassine papers, coated papers, cellulosic sheets such as cellophane, or composites of the above sheets, and the like, which are used as the base sheet 2 of a normal transfer material, can be used.

In order for the base sheet 2 to have release properties, a release layer may be formed on the base sheet 2. In general, the release layer is released together with the base sheet 2 when the base sheet 2 is peeled off after the transfer or the simultaneous transfer with molding. Materials for the release layer include epoxy resin release agents, epoxy melamine resin release agents, amino alkyd resin release agents, melamine resin release agents, silicone resin release agents, and fluororesin release agents. Agent, cellulose derivative release agent,
Urea resin-based release agents, polyolefin resin-based release agents, paraffin-based release agents, and composite release agents thereof can be used.

The release surface of the base sheet 2 may have a hairline 9 or a mat surface. Alternatively, the release surface of the base sheet 2 may be a glossy surface. As a method for forming the hairline 9, there is a method of shaving the surface of the continuously fed base sheet 2 into a hairline with sandpaper. The cross section of the hairline 9 is uneven. The depth of the concave and convex portions is preferably equal to or less than half the thickness of the base sheet 2, for example, 2 μm to 10 μm. As a method of forming the mat surface, there is a method of forming the mat surface on the release surface of the base sheet 2 by a printing method or the like using a resin ink containing pigment.

It is a layer that exhibits a function of preventing fading or the like of the film.

The ultraviolet absorber contains a triazole resin or a triazine resin, and is contained in the protective print layer 3 for the purpose of improving light resistance. Various UV absorbers can be used.

[0029]

Embedded image

Hydroxyphenyl-S-triazine represented by the formula (1) is superior in the ultraviolet absorbing effect (light resistance) of the protective printing layer 3 as compared with the case where another ultraviolet absorbing agent is contained. Further, since the ultraviolet absorber represented by the above formula has excellent compatibility with the active energy ray-curable resin composition, it can be contained in a large amount while maintaining the abrasion resistance and the transparency of the protective printing layer 3. .

The amount of the polymer used for preparing the active energy ray-curable resin composition is set to a specific amount in consideration of the physical and chemical requirements of the protective print layer 3 before and after irradiation with the active energy ray. That is, from the viewpoint of curability upon irradiation with active energy rays, (meth) acrylic equivalent of 100 to 300 g / e
q, preferably 150 to 300 g / eq. When the (meth) acrylic equivalent is more than 300 g / eq, the light resistance after irradiation with active energy rays is insufficient, and 100 g
Those less than / eq are difficult to obtain. Further, from the viewpoint of reactivity with the polyfunctional isocyanate to be subjected to the polyaddition reaction, the polymer has a hydroxyl value of 20 to 500, preferably 100 to 300. When the hydroxyl value is less than 20, the reaction with the polyfunctional isocyanate is insufficient, and the degree of crosslinking of the protective printing layer 3 before irradiation with active energy rays is low. For this reason, tackiness remains or solvent resistance is insufficient. Also, the hydroxyl value is
Those over 500 are difficult to obtain. The weight average molecular weight of the polymer is 5,000 to 50,000, preferably 8,000 to 40,000. If the weight average molecular weight of the polymer is less than 5,000, the adhesiveness of the protective printing layer 3 before the irradiation with the active energy ray remains or the solvent resistance becomes insufficient. On the other hand, if it exceeds 50,000, the resin viscosity becomes too high, and the printing workability of the ink is reduced.

The method for producing the polymer is not particularly limited, and a conventionally known method can be employed. For example, [1] a method of introducing a (meth) acryloyl group into a part of a side chain of a polymer containing a hydroxyl group, [2] α, β-unsaturation containing a hydroxyl group in a copolymer containing a carboxyl group A method of subjecting a monomer to a condensation reaction, [3] a method of adding an α, β-unsaturated monomer containing an epoxy group to a copolymer containing a carboxyl group, and [4] a method of adding an epoxy group-containing polymer. There is a method of reacting an α, β-unsaturated carboxylic acid.

Taking the method [4] as an example, the method for producing the polymer used in the present invention will be described more specifically. For example, a polymer having a glycidyl group is added to an α, β-
The polymer used in the present invention can be easily obtained by a method of reacting an unsaturated carboxylic acid. Preferred as the polymer having a glycidyl group are, for example, a copolymer of glycidyl (meth) acrylate and a copolymer of glycidyl (meth) acrylate and an α, β-unsaturated monomer containing no carboxyl group. No. Examples of the α, β-unsaturated monomer containing no carboxyl group include various (meth) acrylic esters, styrene, vinyl acetate, acrylonitrile, and the like. If an α, β-unsaturated monomer containing a carboxyl group is used, crosslinking occurs during a copolymerization reaction with glycidyl (meth) acrylate, resulting in high viscosity and gelation.

In any case, when each of the above methods [1] to [4] is adopted, the types of monomers and polymers to be used are appropriately determined so as to satisfy the above-mentioned numerical limitation range relating to the polymer. It is necessary to appropriately set conditions such as the amount. Such operations are well known to the parties.

In the present invention, the polyfunctional isocyanate used for preparing the active energy ray-curable resin composition is not particularly limited, and various known materials can be used.
For example, isophorone diisocyanate, xylylene diisocyanate, hydrogenated xylylene diisocyanate, tolylene diisocyanate, diphenylmethane diisocyanate, 1,6-hexane diisocyanate, the above trimer, a prepolymer obtained by reacting a polyhydric alcohol with the above diisocyanate, etc. Can be used.

The ratio of the polyaddition reaction between the polymer and the polyfunctional isocyanate is such that the amount of urethane bonds in the reaction product obtained by the polyaddition reaction is 6,000 to 50,000 g / eq, more preferably 8,000 to 30,000 g / eq. Need to be decided. If the urethane bond amount is less than 6000 / eq, the crosslinking will proceed too much during the polyaddition reaction and a gel will be generated, so that a uniform varnish cannot be obtained. In addition, the urethane bond amount is 50,000g
If it exceeds / eq, the crosslinkability will be insufficient, the tackiness will remain, the solvent resistance will be insufficient, and it will be difficult to obtain the transfer material 1 by an inline printing process such as a ready-made multicolor gravure rotary printing press. .

The active energy ray-curable resin composition contained in the protective print layer 3 of the present invention contains an ethylenically unsaturated group. When the active energy ray-curable resin composition is exposed to active energy rays after the completion of the transfer, the ethylenically unsaturated groups are polymerized and the resin is crosslinked.

The active energy ray-curable resin composition contained in the protective printing layer 3 contains, as necessary, the following components in addition to a reaction product obtained by polyaddition reaction between a polymer and a polyfunctional isocyanate. Can be contained. For example, a reactive diluent monomer, a solvent, a colorant, and the like. When an electron beam is used for irradiation with active energy rays, crosslinking and curing can be sufficiently performed without using a photopolymerization initiator, but when ultraviolet rays are used, various known photopolymerization initiators are added. There is a need to.

The active energy ray-curable resin composition contained in the protective print layer 3 may contain a lubricant, if necessary. This is because the surface of the protective printing layer 3 is roughened, so that it becomes easy to wind as a sheet, and blocking hardly occurs. In addition, resistance to rubbing and scratching can be increased. As the lubricant, for example, waxes such as polyethylene wax, paraffin wax, synthetic wax, montan wax, silicone,
Synthetic resins such as fluorine can be used. Lubricant, 0.5-15
%, Preferably 1 to 6% by weight. If the amount of the lubricant is less than 0.5% by weight, the effect of preventing blocking and frictional scratch resistance is reduced, and if it exceeds 15% by weight, the transparency of the protective printing layer 3 is extremely deteriorated.

The picture printing layer 4 is for decorating the surface of the molded product. Examples of the material of the picture printing layer 4 include resins such as polyvinyl resin, polyamide resin, polyester resin, polyacryl resin, polyurethane resin, polyvinyl acetal resin, polyester urethane resin, cellulose ester resin, and alkyd resin. Is used as a binder, and a colored ink containing an appropriate color pigment or dye as a colorant may be used.

The front anchor layer 5 is a resin layer for improving the adhesion between the picture printing layer 4 and the metal deposition layer 6, and is, for example, a two-component curable urethane resin, a melamine-based or epoxy-based thermosetting resin. Resins and thermoplastic resins such as vinyl chloride copolymer resins can be used.

The metal deposition layer 6 is formed of at least one metal selected from the group consisting of aluminum, nickel, chromium, indium, tin and the like by a vacuum deposition method, a sputtering method, an ion plating method or the like.

The post-anchor layer 7 is a resin layer for improving the adhesion between the metal deposition layer 6 and the adhesive printing layer 8, and is, for example, a two-component curable urethane resin, a melamine-based or epoxy-based thermosetting resin. Resins and thermoplastic resins such as vinyl chloride copolymer resins can be used.

The adhesive print layer 8 is for bonding the above-mentioned layers to the surface of the molded product. As the adhesive print layer 8, a heat-sensitive or pressure-sensitive resin suitable for the material of the molded product is appropriately used. For example, when the material of the molded article is a polyacrylic resin, a polyacrylic resin may be used. When the material of the molded article is a polyphenylene oxide / polystyrene resin, a polycarbonate resin, a styrene copolymer resin, or a polystyrene blend resin, a polyacryl resin, a polystyrene resin having an affinity for these resins, A polyamide resin or the like may be used. further,
When the molded article is made of polypropylene resin, chlorinated polyolefin resin, chlorinated ethylene-vinyl acetate copolymer resin, cyclized rubber, and coumarone indene resin can be used.

Hereinafter, an example of a light-resistant metal vapor-deposited molded product and a method of manufacturing the same will be described. First, the transfer layer is placed inside a molding die composed of a movable die and a fixed die, that is,
Any one of the above-described metal deposition transfer materials 1 is fed so that the base sheet 2 comes into contact with the fixed mold. After the metal mold transfer material 1 is sandwiched in the mold by closing the mold, the molten resin is injected and filled from the gate provided in the movable mold in the cavity to form the resin molded product 10. At the same time, the metal deposition transfer material 1 is adhered to the surface. After cooling the resin molded product 10, the molding die is opened and the resin molded product 10 is taken out.
