この発明は、転写方式による金属化シートの製造に用い
る転写用基材の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention The present invention relates to a method for producing a transfer base material used for producing a metallized sheet by a transfer method.
紙等のシートに金属光沢を付与するに：よ、金属箔を貼
り合わせる方法が一般的であるが、コスト面で考えると
、金属粉を塗布したり、金属蒸着を施す方が有利である
。しかし、金属粉の塗工では充分な光沢が得られず、ま
た、例えば紙のような凹凸の多い表面に直接アルミニウ
ム原着を施しても、同様に灰色の蒸着面しか得られない
。To impart metallic luster to sheets such as paper, it is common to bond metal foil together, but from a cost perspective, it is more advantageous to apply metal powder or perform metal vapor deposition. However, coating with metal powder does not provide sufficient gloss, and even if aluminum is sporadically deposited directly on a surface with many irregularities, such as paper, similarly, only a gray vapor-deposited surface is obtained.
金属光沢の優れた蒸着面をｉ）ようとすれば、紙表面の
凹凸の影響が残らない程度まで樹脂等を塗布して平滑化
したのち、金属蒸着を行なう方法が採られる。しかしな
がら、この方法もコスト的に不利である。In order to create a vapor-deposited surface with excellent metallic luster (i), a method is adopted in which the surface is smoothed by applying a resin or the like to such an extent that the effects of unevenness on the paper surface do not remain, and then metal vapor deposition is performed. However, this method is also disadvantageous in terms of cost.
そこで、特開昭５２−１２４９１２号公報に開示されて
いるように、平滑面を存する被膜支持部を才例えばポリ
プロピレンフィルムに一旦金属笑着を施したのち、この
蒸着膜を紙等に転写する方法が提案されている。Therefore, as disclosed in Japanese Patent Application Laid-Open No. 52-124912, a method is proposed in which a film supporting portion having a smooth surface is coated with a metal, for example, on a polypropylene film, and then this vapor-deposited film is transferred onto paper or the like. is proposed.
このような方法の最も重要な技術課題の一つは、被膜支
持部材の表面に、いかに均一に金属蒸着膜を形成するか
ということであり、他はオングストローム準位のような
穫めて薄い金属蒸着膜を破断させることなくいかに円滑
に被膜支持部材からＩす離して、紙等に転写するかとい
うことである。One of the most important technical issues in this method is how to uniformly form a metal vapor deposited film on the surface of the coating support member, and the other problem is how to uniformly form a metal vapor deposition film on the surface of the film support member. The problem is how to smoothly separate the deposited film from the film support member and transfer it to paper or the like without breaking the film.
この発明は、以上のような課題を解決するために提案さ
れたものである。This invention was proposed to solve the above problems.
以下、この発明の構成を添付図面に基づいて説明する。Hereinafter, the configuration of the present invention will be explained based on the accompanying drawings.

横方向に延伸する。次いで結晶化をはかるため熱処理部
１１で熱処理した後、冷却部１２で冷却を行なう。As shown in the figure, molten polypropylene is extruded into a film from the T-die 2 of the extruded membrane 1, passed through a mirror-finished cooling roll 3 to smooth the surface, and then stretched by a normal stretching method, e.g. by preheating. It is preheated with rolls 6, stretched in the longitudinal direction with stretching rolls 7, and cooled with cooling rolls 8. Thereafter, it is further preheated in the preheating section 9 and stretched in the lateral direction in the lateral stretching section 10. Next, in order to achieve crystallization, a heat treatment is performed in a heat treatment section 11, and then cooling is performed in a cooling section 12.
以上の処理を経て得られたフィルムの表面にコロナ放電
処理を施し、被膜支持部材Ａを形成する。The surface of the film obtained through the above treatment is subjected to corona discharge treatment to form a film support member A.
図中、４はコロナ放電電極であり、５は支持部材Ａを巻

望ましい。In the figure, 4 is a corona discharge electrode, and 5 is a coil around which support member A is wound. Here, in order to form a glossy deposited film during transfer, or to obtain uniform bleed, uniform crystallization, and uniform wettability on the surface of the support member during aging, which will be described later, a mirror-finished cooling roll is used. It is desirable to subject the smoothed film surface to a corona discharge treatment.
さて、上記コロナ放電処理は、支持部材Ａの表面濡れ性
を調整するために行なう。この濡れ性は、実験の結果、
３Ｖ〜３５ダイン／印の間で最良であることが判明した

密着性が強過ぎて転写時に痕着膜がスムーズに剥離せず
、作業性を悪化させるからである。Now, the above corona discharge treatment is performed to adjust the surface wettability of the support member A. As a result of experiments, this wettability is
It has been found that between 3V and 35 dynes/mark is best. If it is less than 31 dynes/am, the adhesion of the metal particles during deposition is poor and a uniform deposited film cannot be formed, and if it exceeds 35 dynes/CIl+, the adhesion to the film support member is too strong. This is because the mark-on film cannot be peeled off smoothly during transfer, resulting in poor workability.
次に、上記のような処理を施した支持部材に、通常の工

めである。Next, metal vapor deposition is performed on the supporting member treated as described above in a normal process, and then further aged for 72 to 120 hours at a temperature of room temperature to 60°C, resulting in a good transfer base material. is obtained. This further promotes the crystallization of the film support member, and the surface of the film support member on which the vapor deposited film is formed.
This is to allow the stabilizer, lubricant, etc. contained in the polypropylene, which is the raw material of the support member, to bleed (infiltrate into the surface) better, and to enable smooth separation of the deposited film.
この熟成処理の温度と時間には、相関関係があり、温度

縮などが生し、逆にあまり温度が低いと熟成に長時間を
要するほか、樹脂の結晶化度の進行が充分でなく強度的
にも劣るので、前述のような温度、時間の範囲が好まし
い。There is a correlation between the temperature and time of this aging process; if the temperature is low, it will take a long time, and if the temperature is high, it will take a short time.
If the temperature is too high, heating will cause deformation and shrinkage of the coating support member, while if the temperature is too low, it will take a long time to ripen, and the crystallinity of the resin will not progress sufficiently, resulting in poor strength. Therefore, the above-mentioned temperature and time ranges are preferable.
以上の処理を施した被膜支持部材を用い、その金属茎着
膜の表面に接着剤を塗布して、例えば紙に圧着接合し、
さらに被ｎり支持部材のみを分離すると、上記蒸着膜は

ことなく円滑に支持部材から、７＋１離される。従って
、このような被膜支持部材は、極めて有用な転写用基材
として市場に提供することができる。Using the film supporting member subjected to the above treatment, an adhesive is applied to the surface of the metal stem adhesion film, and the film is bonded to, for example, paper by pressure bonding.
Further, when only the support member to be covered is separated, the vapor deposited film is transferred to paper. At this time, the deposited film is smoothly separated from the support member by 7+1 without any breakage or the like. Therefore, such a film support member can be provided on the market as an extremely useful transfer base material.
