    Abstract: Disclosed is a microlens array sheet for a liquid crystal display including a first substance layer and a second substance layer having a refractive index less than that of the first substance layer. A plurality of minute unit lenses are formed by providing concaves and/or convexes to an interface between the first and second substance layers. When a ray having entered into the sheet from the normal-line direction of the second substance layer exits from the surface of the first substance layer, an refractive angle relative to the normal line of the surface of first substance layer is not less than 30 degrees. When this microlens array sheet is attached to the surface of a liquid crystal cell of a liquid crystal display, an improved large angle of visibility can be obtained.

    Abstract: A film suitable as a base of image transfer material for thermal recording or a heat-sensitive mimeograph stencil is disclosed. The laminated film of the present invention comprises a coating layer on at least one surface of a polyester film, which coating layer contains as a major component a wax-based composition and has protrusions with length/width ratios of not less than 3 at a density of not less than 20 protrusions/100 .mu.m2. The film of the present invention, when used as a base of an image transfer material for thermal recording or as a film for heat-sensitive mimeograph stencil, the running property is good, abrasion and staining of the head are very small, shedding of ink when the ink is applied does not occur, and the adhesion of the ink, clearness of printed characters, anti-stinking property, holing property and clearness of printing are excellent.

    Abstract: PURPOSE:To obtain a recording sheet in which antistatic properties and ink or toner easy adhesive properties are compatible and which has excellent characteristics by forming a recording layer of a layer formed by sequentially laminating specific dye fixing and ink absorbing layer and a dye permeating and ink absorbing layer. CONSTITUTION:This recording sheet is formed of the sheet made of a recording layer, a film support and a transfer ink layer. The recording layer is formed by sequentially laminating a dye fixing and ink absorbing layer and a dye permeating and ink absorbing layer. The dye fixing and ink absorbing layer is prepared by incorporating crosslinked polyalkylene oxide obtained by reacting polyalkylene oxide having a mean molecular weight of 1000-1000000 with isocyanate compound, colloidal silica, quaternay ammonium salt polymer as main ingredients. The dye permeating and ink absorbing layer is prepared of a layer containing colloidal silica of the shape of coupling and/or branching in prayer beads and water soluble polymer as main ingredients.

    Abstract: PURPOSE:To provide the microlens array with which a sufficient effect of expansing a visual fiels angle is obtd. and observation with plural person is possible by forming a first material layer from a transparent material having a specific refractive index and forming a second material layer from a transparent material having the refractive index larger than the refrac tive index of the first material layer. CONSTITUTION:The observation surface side of a liquid crystal 11 is provided with a microlens array sheet 12, of which the first material layer 1 consists of the substantially transparent material having >=1.35 to =0.20 than the refractive index of the first transparent material. The rear surface of the liquid crystal cell 11 is provide with a rear surfae light source 13 consisting of a prism Fresnel sheet 28, etc., for imparting directivity exit light, As a result, rays transmitted in the cell at an angle of a range not exceeding the critical visual field angle is observed in the display cell part by refraction at the observation surface even in the case the liquid crystal display element is observated from the angle exceeding the critical visual field angle of the display cell and, therefore, a good display grade is obtd. and the visual field angle of the liquid crystal display element is expanded.

    Abstract: PURPOSE:To obtain a recording sheet generating no supply mistake or running inferiority and excellent in the close adhesiveness of toner or ink, in the recording sheet wherein an image receiving layer, a plastic film and an easily slidable antistatic layer are laminated in this order, by forming the easily slidable antistatic layer using a silicone modified quaternary ammonium salt polymer. CONSTITUTION:An image receiving layer composed of a compsn. prepared by adding inorg. and/or org. particles and a polymeric electrolyte or conductive powder controlling surface electric resistance to a polymeric binder if necessary is applied to the corona treatment surface of a plastic film, for example, by a gravure coater. A silicone modified quanternary ammonium salt polymer is diluted to be applied to the surface opposite to the image receiving layer of the plastic film, for example, by a gravure coater to form an easly slidable antistatic layer.

    Abstract: PURPOSE:To obtain the label which does not generate the peeling, rupture, thermal shrinkage and obscure printing of the label in spite of the repetition of cleaning by having a printing surface formed by heat resistant ink and a heat, water and chemical resistant adhesive layer on a plastic film base material. CONSTITUTION:This label is constituted by coating and providing the rear surface of the plastic film base material having the printing surface formed by the heat resistant ink on the surface with the heat, water and chemical resistant adhesive layer. The heat resistance of the heat resistant ink and adhesive is 150 deg.C, preferably 200 deg.C, more preferably 240 deg.C. The adhesive has the sufficient power to withstand detergents, such as powder soap, synthetic detergents, hydrogen peroxide and hypochlorous acid, and hot water. Such adhesive includes adhesives of an acrylic system, silicone system and synthetic rubber system. The plastic film base material consists of one kind of the resins selected from polyester and polyamide. The surface of the adhesive layer of the label is stuck to the cloth.
