摘要： Linear notch patterns at fixed intervals are formed by contacting blades 6a on a drum 6 with a film F and mechanically transferring the shape of the blades 6a to the film F. The notch pattern is formed to be approximately parallel to the axial direction of the drum 6. When a flexural stress is applied in the direction of the film F transport by passing the film over the bending roll 8 while applying a predetermined tension thereto, crazes or cracks are formed inside the notch patterns, with the notches in the notch patterns serving as starting points thereof. Since crazes or cracks are formed using the notch patterns as starting points, relatively large crazes or cracks can be obtained, and optical characteristics can be controlled at a high level.

摘要： [Purpose] To provide a light regulating film and a laminated light regulating film with relatively large crazes or cracks, capable of controlling optical properties such as transmissivity and scattering to a high degree, as well as a method for producing a light regulating film and a method for producing a laminated light regulating film.[Constitution] Linear notch patterns at fixed intervals are formed by contacting blades 6a on a drum 6 with a film F and mechanically transferring the shape of the blades 6a to the film F. The notch pattern is formed to be approximately parallel to the axial direction of the drum 6. When a flexural stress is applied in the direction of the film F transport by passing the film over the bending roll 8 while applying a predetermined tension thereto, crazes or cracks are formed inside the notch patterns, with the notches in the notch patterns serving as starting points thereof. Since crazes or cracks are formed using the notch patterns as starting points, relatively large crazes or cracks can be obtained, and optical characteristics can be controlled at a high level.

摘要： A distributed refractive index type optical transmission plastic article has a circular cross section of a radius r.sub.0 which is in a range of 0.4 to 0.6 mm. A refractive index distribution of the optical transmission article substantially approximates a predetermined ideal refractive index distribution curve at least in a range of 0.25r.sub.0 to 0.70r.sub.0 extending from a center axis toward a peripheral surface of the article. A refractive index n.sub.0 at a central part of the article is in a range of 1.4 to 1.6. The article has a refractive index distribution constant of larger than 0.15 mm.sup.-1 and smaller than 0.3 mm.sup.-1, and a modulation transfer function of at least 55%. This optical transmission article is made from uncured liquid substances each having a viscosity of between 10.sup.3 and 10.sup.8 poises. N (N.gtoreq.2) uncured liquid substances having refractive indexes n of n.sub.1 >n.sub.2 >n.sub.3 . . . n.sub.N when cured are arranged in such a way that the refractive indexes n are successively reduced from a central portion toward a peripheral portion, and concentrically laminated one upon the other to form an uncured strand fiber. The substances between adjacent layers of the fiber are mutually diffused. During the diffusion or thereafter, the uncured strand fiber is cured, thereby completing the production of the optical transmission article.

摘要： An optical component and a method of producing the same, which optical component is obtained by photopolymerizing a photopolymerizable composition so as to comprise a matrix and numerous columnar structure bodies oriented in one direction within the matrix, wherein the columnar structure bodies differ in refractive index from the matrix and are arrayed in a lattice in the plane perpendicular to said orientation direction to have a highly arrayed structure whose refractive index periodically changes on the order of 80 nm to 1,000 micrometer. The optical component according to the invention is imparted with a structure whose refractive index periodically changes with high regularity on the order of about 80 nm to 1,000 micrometer and, owing to this property, is usable in optical sheet, optical film and other ordinary optical applications.
