  • Patent number: 7567383
    Abstract: An anti-glare film has a plurality of diffuser elements, and has specified optical properties. The ratio of I(?+1)/I(?) is more than 0.1 to 0.6, where I(?) is an intensity of a light reflected toward an arbitrary angle ? of 10° or less from a specular reflection direction of an incident light upon the surface at an angle of 5° to 30° from the surface normal, and I(?+1) is an intensity of a reflected light deviated from the arbitrary angle ? by 1° in a wide-angle direction. The gain of a light reflected in the direction at 20° or more from the specular reflection direction of the incident light is 0.02 or less, in which the gain is obtained by normalizing a reflected light intensity using a specular reflection intensity of a standard diffuse plate as 1. The diffuser elements have an average space therebetween of 50 to 300 micrometers.

  • Publication number: 20080206458
    Abstract: A method for producing an anti-glare film includes applying a coating composition including at least a resin, a solvent, and fine particles to a substrate; drying the coating composition applied to the substrate so that a Benard cell structure is formed in the surface of the coating layer due to convection caused during volatilization of the solvent; and curing the resin contained in the coating composition having formed therein a Benard cell structure to form an anti-glare layer having fine irregularities with a moderate surface waviness. The anti-glare layer has a degree of white muddiness of 1.7 or less, as measured by quantitatively determining a diffuse reflection component of the diffused light incident upon the surface of the anti-glare layer.

  • Patent number: 7404998
    Abstract: A synthetic resin card in which card warpage can be reduced and a method for producing the same are provided. By setting the difference ? in the angle of orientation between outer layers symmetrically laminated on a card core section, it is possible to reduce imbalance of stress resulting from the difference in the shrinkage factor between the outer layers, and card warpage can be suppressed. Furthermore, by setting the thickness of the outer layers at 25 ?m to 125 ?m, rising of the surface of the synthetic resin card can be reduced. By reducing the card warpage and the rising of the surface of the synthetic resin card, it is possible to improve moving characteristics when the synthetic resin card is allowed to move in a device.
