摘要： PURPOSE:To obtain a plastic film itself having good adhesion property of a hard coating layer and having scratching resistance and chemical resistance, and to provide its production method and a polarizing plate using this film. CONSTITUTION:A triacetylcellulose film is dipped in an alkali soln. for saponification and a primer layer 2 is formed on the obtd. saponified triacetylcellulose film 1. As for the primer to form the primer layer 2, such a material containing polyvinyl chloride, polyvinyl acetate, and isocyanate is used. Then an ionizing radiation-setting resin is applied on the primer layer 2 and cured to form a hard coating layer 3. Further, an antireflection layer 4 may be formed to obtain an antireflection film. The obtd. plastic film has strong adhesion of the hard coating layer so that no peeling is caused.

摘要： PROBLEM TO BE SOLVED: To provide an antireflection film which can be easily manufactured, gives a hard performance such as scratch resistance and weatherability to the uppermost layer of the antireflection film and can prevent the occurrence of cracking on the uppermost layer even for a deformation of a transparent plastic substrate film. SOLUTION: In the antireflection film, a low refractive index layer 3 essentially consisting of ionizing radiation curable resin composition which includes superfine particles having particle diameter of ≥5 nm and ≤50 nm and refractive index of ≥1.35 and ≤1.45 is formed directly or via other layer on the transparent plastic substrate film 1 as the surface layer. Therein, the low refractive index layer 3 has a refractive index lower than the refractive index of the under layer with which the low refractive index layer 3 is in contact directly and the low refractive index layer 3 is constituted such that the superfine particles are included by ≥30 pts.wt. and ≤300 pts.wt. with respect to ionizing radiation curable resin 100 pts.wt.

摘要： PURPOSE:To provide a transparent functional film which is a transparent functional film having a hard coating layer on a transparent plastic base material, exhibits the function of functional superfine particles by arranging the functional superfine particles so as to deviate extremely at a high density and has an excellent adhesion property of the hard coating layer and the functional superfine particle layer and an antireflection film and a process for producing these films. CONSTITUTION:The functional superfine particle layer 2 is formed on a release film 1. On the other hand, a resin compsn. for the hard coating layer is applied on the transparent plastic base material film 3 and both are laminated by pressurized contact to embed a part of the functional superfine particles 5 into the resin compsn. for the hard coating layer. This release film 1 is peeled after the laminated matter is cured. The functional superfine particle layer 2 of the resulted transparent functional film is partly embedded and fixed into the hard coating layer 4 and the functional superfine particles 5 deviate extremely from the surface of the hard coating layer 4 to the inside. The transparent functional film exposed with a part of the functional superfine particles 5 is obtd. if the release film l formed with the functional superfine particle layer 2 is subjected to pressurized contact while the hard coating layer 4 is in the dry state to touch.

摘要： PURPOSE:To provide a method for forming a close-packed coating film obtained by regularly and closely arranging superfine grains on a substrate only in one layer, especially a coating film suitable to an antireflection film, with a simple method. CONSTITUTION:A liq. dispersion consisting essentially of the mixture of a silica grain 2 and a colloidal silica 3 having a smaller grain diameter than that of the silica grain 2 is used to form a coating film, and the silice grains 2 are regularly and closely arranged on the surface of a substrate 1 only in one layer. A resin binder can be added to the dispersion. With such a close-packed coating film, the refractive index is increased stepwise and gradually from the surface layer in contact with air toward the substrate, and a light reflection preventive effect is produced.

摘要： PURPOSE:To provide a reflection preventing film having excellent adhesion property of the interface between the reflection preventing film and a hard coating layer formed on a base film and having high surface mechanical strength, and to provide its production method. CONSTITUTION:A reflection preventing layer 2 is formed by applying a resin compsn. containing an org. material of low refractive index on a releasing film 1. An ionizing radiation-setting type resin is applied on a transparent base film 3. Then, if the ionizing radiation-setting type resin is diluted with a solvent, the solvent is dried. Or, if the resin is not diluted with a solvent, the releasing film 1 having the reflection preventing layer 2 is laminated as it is on the transparent base film 3 coated with the ionizing radiation-setting type resin. The laminated body is irradiated with ionizing radiations to cure the ionizing radiation-setting resin. Then the releasing film 1 adhered to the cured body is peeled.
