摘要： A package of a heat-bent polarizing sheet for producing an injection-molded polarizing lens, in which a laminated polarizing sheet prepared by bonding a transparent plastic sheet onto each of two sides of a polarizing film formed of a uniaxially stretched polyvinyl alcohol resin film with an adhesive layer interposed therebetween is used as an individual laminated polarizing sheet that has an original plate shape for individual lenses, the individual laminated polarizing sheet is heat-bent to form a spherical aspherical surface under heating to prepare a heat-bent polarizing sheet, the heat-bent polarizing sheet is set onto a mold, and a transparent resin for lenses is injection-molded onto a concave surface of the heat-bent polarizing sheet. The heat-bent polarizing sheet is a heat-bent polarizing sheet that is stored or transported in a dampproof package and can be used in injection molding without performing preliminary drying as a pretreatment of injection molding.

摘要： A package of a heat-bent polarizing sheet for producing an injection-molded polarizing lens and an injection-molded polarizing lens that uses said sheet is provided. The heat-bent polarizing sheet is cumulatively packaged by a non-adhesive isolation film so as to withstand moisture and then stored or transported and can be used in injection molding without performing preliminary drying as a pretreatment of injection molding and without substantial protective-film removal work.

摘要： A resin composition includes a phenoxy resin as a principal component. The phenoxy resin has a weight-average molecular weight of 40,000 or more. The phenoxy resin has, in the same or different molecules, a first structural unit derived from bisphenol S phenoxy and a second structural unit derived from a bisphenol epoxy other than the bisphenol S phenoxy. A content ratio of the first structural unit in the phenoxy resin is 20 mol% to 80 mol% relative to a total content of the first structural unit and the second structural unit constituting the phenoxy resin.

摘要： A method for producing an insulated electric wire includes a step of preparing a conductor having a linear shape; a step of forming an insulating coating so as to cover a surface on an outer peripheral side of the conductor to obtain an insulated electric wire that includes the conductor and the insulating coating covering the conductor; and a step of measuring a first electrostatic capacity between the insulated electric wire and a first electrode disposed outside in a radial direction of the insulated electric wire so as to face an outer peripheral surface of the insulated electric wire while transporting the insulated electric wire in a longitudinal direction of the conductor, and inspecting a formation state of the insulating coating, the formation state including a formation state of a defective portion in the insulating coating, on the basis of a change in the first electrostatic capacity.

摘要： At least a surface of a reel pallet is made of resin. When a distance in a first direction between a reel supported by a first reel support and a reel supported by a second reel support is denoted by La, a distance in the first direction between an outer edge of the reel supported by the second reel support and a fourth side of an arrangement surface is denoted by Lb1, and a distance in the first direction between an end surface of the reel supported by the first reel support and a second side of the arrangement surface is denoted by Lb2, the reel pallet satisfies a relationship of 1
