摘要： PURPOSE: To obtain a compsn. which can form a porous film merely by applying to a substrate and drying without detriment to film characteristics and to prepare a porous film formed from the compsn. and to provide a method for forming a porous film from the compsn. CONSTITUTION: The compsn. is prepd. by mixing a film-forming emulsion comprising water an particles of a synthetic resin having hydrogen-bond-forming groups with at least one organometallic compd. which can form hydrogen bonds. The amt. of the organometallic compd. mixed is 0.01-30 times the amt. necessary to cover the particles. An inorg. component formed by the hydroysis and condensation of the organometallic compd. coveres at least a part of the surfaces or insides of the particles, thus partially preventing the fusion or bonding between the particles in the drying step after the application and forming voids to give a porous film.

摘要： PURPOSE: To provide an antireflection film in which the adjustment of the refractive indices of the lower layers in direct contact with the low-refractive index layers of an antireflection sheet having the low-refractive index layers and high-refractive index layers to the refractive indices sufficient for generating an antireflection effect is facilitated, which has an excellent adhesion property to the respective layers, hardly generates crack, etc., and has excellent productivity. CONSTITUTION: The low-refractive index layers 4 which are surface layers are formed via other layers 2 on at least one surface of the front and rear surfaces of a transparent base material film 1. At least one of the other layers 2 consist of a high-refractive index layer 3 formed by bonding high-refractive index superfine particles to each other with a binder resin. The high-refractive index layer 3 is in direct contact with the low-refractive index layer 4 and the refractive index of the high-refractive index layer 3 is higher than the refractive index of the layer in contact with the surface of the high-refractive index layer 3 on the side opposite to the low-refractive index layer 4 side. The film thickness D of the high-refractive index layer 3 is expressed by the equation. In the equation, (n) is the refractive index of the high-refractive index layer 3, λ is the wavelength (380

摘要： PURPOSE:To enable a product having an excellent adhesive property and excellent plate water to be obtained at good productivity by a method wherein polyurethane resin and/or radiation setting polyurethane resin and (meth)-acrylate monomer having at least one hydroxyl group are taken as seed components of an adhesive for thermosensitive stencil base paper. CONSTITUTION:Polyurethane resin and/or radiation setting polyurethane resin and (meth)acrylate monomer having at least one hydroxyl group are taken as components of the title adhesive. Then, the abovementioned adhesive is applied to one side surface of a porous base material or a thermoplastic resin film to laminate the thermoplastic film or the porous base material on the surface. Then, they are bonded to each other by irradiating them with radiation to manufacture thermosensitive stencil base paper. Consequently, a product having an excellent adhesive property and excellent plate wear can be obtained at good productivity.

摘要： PURPOSE:To improve antistatic performance and carrying performance by containing an antistatic agent in a porous support reinforced with resin in a minemo-type stencil paper where a thermoplastic resin film is laminated on one surface of the porous support through an adhesive layer. CONSTITUTION:A porous support, e.g. a paper, a synthetic paper or a fiber mixed paper having grammage of 5-12g/m , is employed in order to allow passage of printing ink at the time of printing. In the minemo-type stencil paper, an antistatic agent and a resin are contained in the porous support. The antistatic agent includes cationic, anionic and nonionic agents. The resin, i.e., the reinforcing agent for the porous support, has Tg higher than 40 deg.C. A radiation curing adhesive composed of a polyurethane resin and a monofunctional or a multifunctional (meta)acrylate is employed for bonding the porous support and the thermoplastic resin film.

摘要： PURPOSE:To enhance scratch resistance, abrasion resistance, flexibility and bendability, by coating a film with a resin composition containing a specific amount of an urethane compound having specific diol and a polymerizable unsaturated group in the skeletal thereof and a specific amount of a monomer having a radical polymerizable unsaturated group and irradiating the coated film with electron beam. CONSTITUTION:A coating solution 3 composed of a resin composition is applied to a support film 1 using a coating apparatus 2. Next, a mirror surface material 4 is laminated to the support film 1 so that the mirror surface thereof is turned to said film 1 and the coating film is cured by an electron beam irradiation device 5 and, at last, the mirror surface material 4 is released. The resin composition is prepared by containing 50-400 pts.wt. of a monomer having at least one radical polymerizable unsaturated group in one molecule thereof in 100 pts.wt. of an urethane oligomer prepared by bonding isocyanate, diol having hydroxyl groups at both terminals thereof and a wt. average MW of 200-300 and an acrylate compound having a hydroxyl group at the terminal thereof and a radical polymerizable unsaturated group. Further, by using a sheet or panel having a matte surface in place of the mirror surface material, non-glare properties are obtained.
