摘要： PURPOSE:To provide an reflection preventing film having both of reflection preventing property and hard performance so that reflection of light on interfaces between inner layers can be reduced and to provide its production method and a polarizing plate and liquid crystal display device using this antireflection film. CONSTITUTION:A low refractive index layer 13 as the surface layer is formed on a transparent substrate film 11 with other layers interposed. At least one of other layers is a high refractive index hard coating layer 12 of >=0.5mum thickness essentially comprising a resin. This high refractive index hard coating layer 12 is directly in contact with the low refractive index layer 13. The refractive index of the high refractive index hard coating layer 12 is higher than the refractive index of the layer in contact with the opposite side to the low refractive index layer 13 side. This reflection preventing film is used for a polarizing plate and a liquid crystal display device by laminating.

摘要： PURPOSE:To stick fast a thermoplastic resin film to a mesh screen without reducing a punching sensitivity even if the quantity of an adhesive is small by using water emulsion adhesive or water soluble adhesive as an adhesive and applying the adhesive only to a lattice face of the screen. CONSTITUTION:A mesh screen 1 is passed through an adhesive liquid 2, a thermoplastic resin film 3 is laminated thereon, and dried by a drier 4. After the mesh screen 1 and the film 3 are laminated, the film 3 is made to be in a lower part in the process of drying. As an adhesive liquid, an adhesive aqueous solution or water emulsion is to be used. Preferably, a solid of the adhesive is to be 20 weight % or less and 1-20 weight % is more preferable. For example, the aqueous solution or emulsion of acrylic or polyester thermoplastic resin is used. Further, a thermal hardening adhesive of phenol resin, epoxy resin, and alkyd resin can also be used. The support body 1 as a mesh screen and the thermoplastic film 3 are stuck by the adhesive layer 2 at the lattice maintaining part.

摘要： PURPOSE:To obtain an excellent gradation image by forming the perforations corresponding to the quantity of the heat supplied from a thermal head by using a film wherein the sum of a longitudinal heat shrinkage factor and a lateral heat shrinkage factor at specific temp. is below a specific ratio. CONSTITUTION:The thermoplastic resin film laminated to one surface of a porous support is set to below 10% in the sum of a longitudinal heat shrinkage factor and a lateral shrinkage factor at 110 deg.C. For example, a polyethylene terephthalate film of 1.8mum thickness whose heat shrinkage factor at 110 deg.C is 2.0% in both of longitudinal and lateral directions is laminated to the porous paper support (thickness ; 40mum, basis wt. ; 10.3g/m ) through an adhesive layer (polyester resin/acrylic ester wt. ratio ; 3/2). Further, a resin composition is applied to this thermoplastic resin film in predetermined thickness and dried to form a thermal fusion preventing layer to obtain thermal screen printing base paper.

摘要： PURPOSE:To form stencil paper for thermosensitive stencil with excellent performance and sensitivity by laminating thermally plastic film of thermally plastic resin elongated with two spindles with specific crystal fusion heat on one surface of a porous support through an adhesive layer. CONSTITUTION:On one surface of a porous support, thermally plastic resin film is used Which has the DELTAHu of not more than 3cal/g. The support used is porous so that passage of printing ink is allowed, and is Japanese paper, synthetic paper or paper of mixed fibers with the basis weight of about 8 to 12g/m . If DELTAHu is 3cal/g or more, the crystallity of film becomes high and reaches a highmelting point, so that the amount of energy supplied to a thermal becomes large. In addition, the size of a perforated hole depends largely on the amount of energy supplied. For this reason, the density and resolution of print are significantly influenced by a slight change in the amount of energy supplied. If the amount of energy supplied to the thermal head as small, print with high density and resolution can be obtained, regardless of variations of applied energy, by using thermally plastic resin film with fusion energy of not more than 3cal/g.

摘要： PURPOSE:To form stencil paper with high performance and sensitivity for thermosensitive stencil by laminating thermally plastic films of thermally plastic resin elongated with two spindles which has a difference of 100 deg.C or more between a fusion starting temperature and a fusion ending temperature, on one surface of a porous support through an adhesive layer. CONSTITUTION:Films to be laminated on one surface of a porous support through an adhesive layer are thermally plastic films elongated with two spindles, and have a difference (DELTATm) of 100 deg.C or more between their fusion starting temperature and fusion ending temperature. If the support is porous so that it allows passage of ink, its quality is not particularly specified. However, for instance, Japanese paper, synthetic paper or mixed fiber paper with a basis weight of about 8 to 12g/m can be used. Printing with high density and resolution can be achieved, regardless of variations of the content of energy supplied to a thermal head, by using thermally plastic film with a difference (DELTATm) of 100 deg.C or more between its fusion starting temperature and fusion ending temperature as thermally plastic film.

摘要： PROBLEM TO BE SOLVED: To provide a film having excellent durability, transparency and antistatic properties for adhering to various display surfaces such as a surface of a flat CRT glass, wherein a phosphor surface side and an outside surface of the CRT glass has different curvatures, and for preventing generating of a color shading common with a colored glass. SOLUTION: An antistatic colored hard-coated film consists of a transparent base film 1, a transparent conductive layer 4 provided on one side of the transparent base film 1, a hard-coated layer 5 provided on the transparent conductive layer 4, an adhering layer 3 provided on the other side of the transparent base film 1 and a release film provided on the adhering layer 3. The antistatic hard- coated film has a colored layer 2 between any two layers or has any layer containing a coloring material. If the hard-coated layer 5 has an anisotropic conductivity, transparency and antistatic properties are further improved.

摘要： PROBLEM TO BE SOLVED: To provide a coating film hardening method in which the adhesion between the substrate and the coating film and between the coating films is improved by effectively utilizing the irradiation spectrum of the UV source when the coating film of a UV-curing resin composition except the outermost surface layer is half-cured, and the coating films of the UV-curing resin composition are irradiated with UV and hardened at the same time. SOLUTION: A photosetting initiator reacting on the wavelength characteristic of a UV source is selectively used, and the photosetting initiators having different peaks of the absorption wavelength range are respectively mixed in each of the plural coating film layers of a UV-curing resin composition. The peak of the absorption wavelength range of the photosetting initiator to be added to the lower-layer coating film should be on the longer wavelength side of the peak of the absorption wavelength range of the initiator to be added to the upper-layer coating film to efficiently utilizing the wavelength characteristic of the UV source when the formed plural layers of the coating films of the UV-curing resin compositions are hardened. This method is applied to the production of a functional film and to an antistatic hard coat film.
