摘要:
A resin-coated metal plate having a metal substrate and, formed on the surface thereof, a thermoplastic resin layer, characterized in that the thermoplastic resin layer comprises a polyester containing polyethylene terephthalate as a main component and an ethylene polymer and further comprises tocopherol or a derivative thereof. The resin-coated metal plate exhibits good corrosion resistance and impact resistance (dent resistance) together with good resistance to an atmosphere of both high temperature and high humidity, and thus can be subjected to retort sterilization and can be held in a hot vender after retort sterilization.
摘要:
A resin-coated metal sheet comprising a metal substrate and a thermoplastic resin layer formed on the surface of the metal substrate, wherein the thermoplastic resin layer comprises a polyester consisting chiefly of a polyethylene terephthalate and an ethylene polymer, and contains an ionomer resin as well as a tocopherol or a derivative thereof. The resin-coated metal sheet exhibits corrosion resistance, shock resistance (dent resistance) and resistance against high temperature and humidity, and withstands the retort-sterilization and the aging in a hot vendor or the like after the retort-sterilization.
摘要:
Dots for producing a multiple tone electrostatic latent image are formed by selectively discharging a charged surface with a scanned laser beam. The multiple tones are produced by pulse width modulation of the laser beam according to the tones required in the dots. High resolution is maintained by limiting the diameter of toner particles to 1/5 to 5 times the minimum exposed dot dimension. A laser beam exposure device includes a galvanometer mirror from which the scanning laser beam is reflected. The galvanometer mirror is tilted in synchronism with the conveying direction of the surface being scanned in order to maintain focus of the laser beam on the surface. In one embodiment, the modulation of the laser beam is produced by a combination of a digital counter and a delay circuit. The counter counts clock pulses until a first specified value is reached. A counter output pulse is generated during this counting. The delay circuit extends the counter output pulse to yield the final output pulse width. A developing system applies a positive voltage to a surface of a first conductor over which an object containing the electrostatic latent image is moved. A toner suspension is applied to the surface during this time. The object on which the image is being developed and a second conductor, adjacent a second surface of the first conductor, are given ground potential.

This invention discloses a printed metal container having an organic resin coating film layer containing titanium oxide having photosensitivity characteristics of I x t1/2
摘要:
A multi-color image formed on a belt by electrophotography is fixed to the portion to be printed of a container consisting of metal, glass, plastic, paper or the like, through a single thermal transfer process. A multi-color image is formed on a plastic film laminated on a belt by utilizing electrophotography and a firm multi-color printing surface is formed by transferring and fusing the plastic film onto a container as the object of printing. Furthermore, when a multi-color image is formed by utilizing electrophotography, exposure light is applied from the back of a photosensitive member and multi-color printing free from color shift is completed by preventing the exposure light from being cut off by a toner image.

摘要:
The toner is deposited on a metal sheet or a metal container by electrophotographic units (3), (4), (5), during which the toner is tentatively fixed at a low temperature by a tentative fixing unit (9), and it is finally fixed at a higher temperature by a fixing unit (9a) to complete a printing operation. A photosensitive layer may be laminated directly on the surface of the metal sheet or metal container, or on a photosensitive drum. A solid printed surface can be obtained by applying finishing varnish to the surface of the toner layer.
