摘要： PURPOSE:To obtain the subject composition containing a flame retardant at a specific ratio, being transparent, having self-repairing properties and scratch resistance as well as flame retardancy. CONSTITUTION:This product is obtained by molding a transparent and flexible resin composition containing 1-50wt.% of a flame retardancy based on total weight of the resin composition and having self-repairing property and scratch resistance (preferably a resin composition consisting essentially of a crosslinked type non-yellowing polyurethane-based resin), preferably by a reactive bulk casting method. Furthermore, as the flame retardant, a combination of a phosphorus-based flame retardant and a bromine-based flame retardant is preferably used. The phosphorus-based flame retardant includes preferably triphenyl phosphate or trichloroethyl phosphate. The bromine-based flame retardant includes preferably diglycidyl ether of tetrabromobisphenol A and its oligomer.

摘要： PURPOSE:To provide a laminate improved in loss factor and enhanced in sound- absorbing properties by constituting the laminate of polyvinyl chloride and a plasticizer and setting the difference between the solubility parameters of both of them to a predetermined value or less. CONSTITUTION:In a laminate consisting of a hard transparent plate and a film or sheet composed of a polyvinyl chloride resin compsn., the polyvinyl chloride resin compsn. contains polyvinyl chloride and a plasticizer and the difference between the solubility parameters (sp values) of them is set to 0-+ or -2 or less. As the plasticizer, for example, phthalic ester or fatty acid (dibasic) ester is designated and the difference between the sp values of the plasticizer and polyvinyl chloride is pref. within 0+ or -2. The polyvinyl chloride resin compsn. pref. contains 100 pts.wt. of polyvinyl chloride with an sp value of about 20 and 5-60 pts.wt. of dimethylphthalate. As the hard transparent plate, a glass plate is pref.

摘要： PURPOSE:To impart excellent self-repairability and scuffing resistance by laminating a soft resin layer on an optically controllable laminated body. CONSTITUTION:Transparent hard resin protective layers are provided on both faces of an optically controllable resin film provided with a function, which selectively diffuses incident light only in a prescribed angle area and transmits incident light from the other angle. Furthermore, the soft resin layer substantially transparent and excellent in self-repairability and scuffing resistance is laminated at least on one of the protective layers. As the soft resin layer laminated on the surface, polyurethane based resin is preferably used from the view point of the balance among transparency, self-repairability and the scuffing resistance and particularly non-yellowing polyurethane based resin is preferable from the view point of durable yellowing resistance. And the optically controllable laminated body can be pasted on window glass so as to impart the optical control function to window glass by providing an adhesive layer on the rear face.

摘要： PURPOSE:To obtain an adhesive compsn. which has a refractive index easily made equal or close to that of an essentially transparent adherend by adding a specific compd. as the refractive index modifier to a hot-melt urethane adhesive. CONSTITUTION:Pref. a nonhalogenous phosphoric ester. a halogenous phosphoric ester, or an arom. organophosphorus compd. prepd. by the condensation of a halogenous phosphoric ester (e.g. a condensate of phosphoryl chloride, phenol, and resorcin) is added as the refractive index modifier to a hot-melt urethane adhesive [e.g. obtd. by reacting a polyester polyol with methylenebis (cyclohexyl isocyanate) and isophorone diisocyanate and then with 1,4-butanediol].

摘要： PURPOSE:To obtain the high coefficient of losses and decrease the dependency thereof by laminating an intermediate film with a specific thickness of vinylchloride copolymer containing dimethylphthalate between transparent rigid sheets with a specific thickness. CONSTITUTION:The sound insulation transparent rigid laminated body is obtained in such a manner that an intermediate film with a thickness of 0.1-1.5mm of vinyl chloride/vinylidene chloride copolymer containing dimethylphthalate between transparent rigid sheets with a thickness of 1.9-10mm is laminated. The unit of vinylidene chloride copolymerized acts to lower the melting point of copolymer to render the treating property excellent, in addition, to improve the inner losses, therefore, copolymer is preferably employed here in which the unit of vinyl chloride polymerized is 30-60wt.% and the unit of vinylidene chloride polymerized is 40-70wt.%. When the unit of vinyl chloride polymerized is less than 20 wt.%, the copolymer obtained is likely to be worse in coporimerization, and also to be worse in heat stability. On the contrary, when it comes to be 90 wt.% or more, the inner losses can not be obtained. In the case of dimethylphthalate, a high coefficient can be obtained through the action as a plasticizer.
