  • Publication number: 20120015144
    Abstract: Disclosed is a transparent electroconductive laminate which achieves the required transparency or haze characteristic while having a desirable slipperiness in terms of handleability. Further disclosed is a transparent touch panel having said transparent electroconductive laminate. The transparent laminate (10) has a transparent organic polymer substrate (1), a transparent electroconductive layer (2) on one face of the transparent organic polymer substrate, and a cured resin layer (3) with a concavo-convex surface on the other face of the transparent organic polymer substrate, and the transparent touch panel has said transparent electroconductive laminate. The cured resin layer (3) has a concavo-convex surface by being formed from a coating composition which contains two types of polymerizable components which mutually phase-separate on the basis of the physical difference therebetween.

  • Publication number: 20070112108
    Abstract: It is an object of the present invention to provide a styrene type resin composition excellent in thermal stability, hue, fluidity, and heat resistance, and also having the flame retardant performance, and a molded product excellent in outward appearance, formed therefrom. The present invention provides a flame retardant styrene type resin composition comprising (A) a styrene type resin (component A) in an amount of 100 parts by weight, (B) a polyphenylene ether type resin (component B) in an amount of 0 to 100 parts by weight, and (C) an organophosphorus compound (component C) represented by the following formula (1) in an amount of 1 to 100 parts by weight, characterized in that the organophosphorus compound (component C) satisfies: (i) the weight loss residue on heating at 500° C. is 10% or less; (ii) the HPLC purity is 90% or more, and (iii) the acid value is 0.5 mg KOH/g or less (where in the formula, Ar1 and Ar2 may be the same or different, and is a phenyl group which may have a substituent.

  • Publication number: 20030024149
    Abstract: To provide a lure in which an elemental line passing through an interior of a lure body is positively drawn backwardly of the lure body upon the fishing-on, so that fish that has been hooked on a fishing hook and the lure body may be kept at a predetermined distance also by the dragging action of the fishing line, and fish will not readily be released from the fishing line even if the fish on the hook struggles. A through-hole is formed from a tip end portion of the lure body 1 to a portion where the fishing hook 9 is mounted in the interior portion of the lure body. The elemental line 4 having a length longer than said through-hole is caused to pass through the through-hole. A front end of the elemental line that has been drawn out of the opening end 2a of the through hole on the front end side of the lure body is fixed swingably along the fishing line L fixed to the tip end portion of the lure body.

  • Patent number: 4139675
    Abstract: Recording paper for use in, for example, an electrostatic recording system, comprising an electrically conductive base layer, a photoconductive or dielectric recording layer disposed on one surface of the base layer, and a heat-sensitive bonding layer disposed on the other surface of the base layer. The bonding layer is non-tacky at normal temperature, and it develops tackiness when heated after a recording has been made on the recording paper.
