と云う問題もあつた。 It is thought that a film that can optically change the irradiated light beam through light-changing effects such as spectroscopy and reflection due to its uneven surface can be used for interior decoration, but conventionally used uneven surface films, such as As disclosed in Japanese Patent Application Laid-open No. 52-117368 and Japanese Patent Application No. 56-56660 (Japanese Patent Laid-Open No. 57-170718), it is made to take advantage of the unevenness of the uneven surface.
If this is used directly for interior decoration, etc., there is a problem that the uneven surface may become clogged with dust or be damaged by collisions with external objects, causing the uneven surface to lose its spectroscopy and diffuse reflection effects. Another problem is that because the decorative effect is obtained only by the light-changing effect of the uneven surface, the decorative effect is unified and there is little variation.
本発明はこの様な不利益を一掃し得る変光フイ
ルムの製造方法を提供せんとするものである。 The present invention aims to provide a method for manufacturing a variable light film that can eliminate these disadvantages.

ルムＦを得る事を特徴としたものである。 The method of the present invention will be explained below with reference to the accompanying drawings. In the method of the present invention, an endless mold plate 1 in which a large number of fine grooves have been formed in advance is rotated or circulated so that the mold surface 1a continuously moves. A part of the plate 1 enters a liquid tank 2, and a photocurable resin liquid 3 is contained in the liquid bath, and the liquid photocurable resin is applied to the mold surface by rotating or circulating the mold plate 1. A light source 4 for curing the photocurable resin is provided opposite to the mold plate 1, and light irradiation from the light source 4 causes the mold to be attached to the mold plate 1a and taken out continuously from the liquid tank 2. The photocurable resin attached to surface 1a and taken out is then placed on mold surface 1.
Then, the film 3' cured on the mold surface 1a is peeled off and recovered from the mold surface 1a, and then the uneven surface 3a of the film 3', that is, the surface peeled off from the mold surface, is It is guided to the second liquid tank 8 so as to face downward, and this liquid tank 8
A liquid transparent resin material 9 having a different optical refractive index from the resin material of the film 3' is contained therein,
This transparent resin material 9 is applied to a film 3' as shown in FIG.
Then, the variable film base material thus produced is pulled out of the second liquid tank 8, and the transparent resin material 9 is cured, thereby forming a transparent surface layer 9'. This method is characterized by obtaining a variable light film F in which .

反射作用を助長するものであるから、透明な事と
光屈折率がフイルム３′と異なる事とが充足され
れば硬化性が何によつて得られるかは問題としな
くても良い。 As the transparent resin material 9 used in this invention, for example, a photocurable resin may be used, and the surface layer 9' formed of this transparent resin material 9 covers the uneven surface 3a' of the film 3'. Since it protects the uneven strips 3a from external dust and promotes the spectroscopic effect and diffuse reflection effect of the uneven surface 3a', it is curable as long as it is transparent and its optical refractive index is different from that of the film 3'. It does not matter what is used to obtain this.
以上の処において、上記型版１の型面１ａは、
フオトエツチング法やレーザー光線による加工方
法等により成形すれば良く、例えばレーザー光線
を使用する場合には、アルミニユーム板に１mm幅
600本程度の条溝を刻設する事が出来るから、フ
イルム３′に極めて微小な凹凸条を得る事が出来
る。 In the above, the mold surface 1a of the mold plate 1 is
It may be formed by photo etching method or laser beam processing method.For example, when using laser beam, 1mm width is formed on aluminum plate.
Since about 600 grooves can be carved, it is possible to obtain extremely minute uneven grooves on the film 3'.
上記型版１は、第１図に示す如く、ドラム型に
構成するのが良好であるが、場合によつては無端
ベルト状に構成しても良い。 As shown in FIG. 1, the template 1 is preferably formed into a drum shape, but may be formed into an endless belt shape as the case may be.
上記型面１ａの条溝１a′は、第３図Ａの如く、
断面鋸歯型に作るのが、分光効果の上から望まし
いが、場合によつては他の形状、例えば第３図Ｂ
の如く断面段状凹凸型や、第３図Ｃの如く断面波
形に作つても良い。 The grooves 1a' on the mold surface 1a are as shown in FIG. 3A,
It is desirable to make the cross-section into a sawtooth shape from the standpoint of spectral effects, but in some cases other shapes may be used, such as Fig. 3B.
It may be made to have a step-like uneven cross-section as shown in FIG. 3C, or a corrugated cross-section as shown in FIG. 3C.
又上記条溝１a′は、通常型面１ａの移行方向と
直交する方向に刻設されるが、場合によつては型
面１ａの移行方向に沿つて刻設しても良く、或は
又移行方向と斜向する様に刻設しても良い。 Further, the grooves 1a' are usually carved in a direction perpendicular to the direction of transition of the mold surface 1a, but in some cases they may be carved along the direction of transition of the mold surface 1a. It may be engraved so as to be diagonal to the transition direction.
更に又上記型面１ａはフオトエツチング法等に
より模様面に作つても良く、この場合には条溝１
a′が模様パターンを線描する事になる。 Furthermore, the mold surface 1a may be formed into a patterned surface by photo-etching or the like, and in this case, the grooves 1
A' will draw the pattern.
上記光硬化性樹脂としては、柴外線硬化性樹脂
があり、この種樹脂から目的に適する物質を選定
して使用すれば良く、この時併せてフイルムの透
明度も決定される。 As the photocurable resin, there is a Shigai radiation curable resin, and a material suitable for the purpose may be selected from these resins and used, and at this time, the transparency of the film is also determined.
上記型面１ａで硬化してフイルム３′となつて
光硬化性樹脂は、第１図に示す如く、例えばスト
リツパ５で剥離されると共に変光フイルムＦは巻
取ローラ６で巻取られて回収されるが、この時型
面１ａの条溝１a′が目詰まりする虞れがあるか
ら、例えば吸気型クリーナー７で型面１ａを清掃
する事が望ましい。本発明方法はこの様なもので
あるから、下記効果を期待出来る。 The photocurable resin is cured on the mold surface 1a to form a film 3', and as shown in FIG. However, at this time, there is a risk that the grooves 1a' on the mold surface 1a may become clogged, so it is desirable to clean the mold surface 1a with, for example, an intake type cleaner 7. Since the method of the present invention is as described above, the following effects can be expected.
張力の極めて小さい樹脂液を型面１ａに附着さ
せてフイルムにするため、薄質で且つ変形しない
変光フイルムを作る事が出来、従つて室内装飾用
として加工が楽である。 Since a resin liquid with extremely low tension is attached to the mold surface 1a to form a film, a thin variable film that does not deform can be made, and therefore can be easily processed for interior decoration.
フイルム３′の凹凸条３ａが正確に成形される
と共に保形成が良好なため、各凸条ａをプリズム
状に成形する場合においても、凸状３ａの分光作
用を良好に確保出来る利益がある。 Since the concavo-convex strips 3a of the film 3' are accurately formed and well-retained, there is an advantage that even when each convex strip a is formed into a prism shape, the spectral action of the convex portions 3a can be ensured well.
フイルム３′の凹凸面３a′が、該フイルムと光
屈折率の異なる表層９′で被覆されているから、
フイルム３′の凹凸面３a′が塵埃等で消失する事
を防げる他、表層９′の光屈折率を選定する事で
変光フイルムＦの分光特性や乱反射特性を変える
事が出来ると共に表層９′による光干渉作用も期
待出来るから、此等の変光作用により装飾的効果
を大きく出来、且つ又装飾的効果の異なる多種の
変光フイルムＦを製造出来ると云う効果がある。 Since the uneven surface 3a' of the film 3' is covered with a surface layer 9' having a different optical refractive index from that of the film,
In addition to preventing the uneven surface 3a' of the film 3' from disappearing due to dust, etc., by selecting the optical refractive index of the surface layer 9', the spectral characteristics and diffuse reflection characteristics of the variable light film F can be changed, and the surface layer 9' Since the light interference effect can be expected, the decorative effect can be increased by this light-changing effect, and it is also possible to produce a wide variety of variable light films F with different decorative effects.
