摘要:
A light-reflecting panel is proposed, provided with a constitution wherein a fine powder-containing polyester layer comprising an aliphatic polyester series resin and a fine powder filler is layered over one face or both faces of a metal plate, as a light-reflecting material, which is thin and allows for form-processing, provided with a high degree of reflection capability while at the same time preventing a decrease in reflectance due to ultraviolet irradiation. This light-reflecting material allows excellent light reflectivity to be obtained by refractive scatter due to a difference in the refractive indices of the aliphatic polyester series resin and the fine powder filler constituting the fine powder-containing polyester layer, is characterized by almost no decrease in reflectance due to ultraviolet irradiation occurs since the aliphatic polyester series resin constituting the fine powder-containing polyester layer does not have aromatic rings that absorb ultraviolet light, and can be made into a thin type light-reflecting panel since it can be layered directly onto a metal plate without using an adhesive.
摘要:
A thermoplastic resin-coated aluminum plate is provided which is less liable to develop ply separation or cracks in a resin coating film during drawing or ironing and on which the resin coating film is less likely to peel off the aluminum plate. A semi-non-porous anodized film is formed on at least one side of the aluminum plate, a coating layer is formed on the semi-non-porous anodized film, and a thermoplastic resin coating film is formed on the coating layer.

Provided is a transparent laminated film having excellent transparency and heat dimensional stability at high temperatures, which can be produced using a simple production process. This is to be a transparent laminated film, which is a laminated film of a constitution in which a cured layer of curable resin composition is laminated on both sides of a base film, the storage elastic modulus (E′) by dynamic viscoelasticity measurement in the longitudinal direction of the laminated film at 200° C. temperature is greater than the storage elastic modulus (E′) of the base film in the same conditions, and the total light transmittance of the laminated film is 80% or greater.
摘要:
A locking device for electronic parts each having two or more lead wires, including clinch pawls which can move a little when they abut on the lead wires. The small movement of these clinch pawls is detected by a detection mechanism and utilized to confirm if a given electronic part has been mounted on a print-circuit board.
摘要:
A cellulosic plastic article, such as an article of cellulose propionate, cellulose acetate butyrate or cellulose butyrate, is coated with good adhesion of an applied coat by pretreating the surface of the article with an aqueous solution containing an alkali metal and an alcohol, then applying a coating composition comprising a thermosetting resin to the treated surface, and curing the coating.
摘要:
A surface hardening coating composition for cellulosic plastics, comprising as a hardening component a mixture consisting of (a) methylolmelamine with at least part of its methylol groups optionally alkyl-etherified and (b) 0.1 to 1.5 equivalents, per equivalent of the methylolmelamine, of an aliphatic or alicyclic compound having at least two functional groups capable of reacting with the methylol groups or alkyl ethers thereof, and/or a precondensation product between the components (a) and (b). Shaped articles of cellulosic plastics having superior abrasion resistance and flexibility can be prepared by coating the surface of a shaped article of cellulosic plastics with the above composition and baking the coated article at a temperature from 60.degree. C. to the heat distortion temperature of the article.
