摘要:
Antimicrobial agents comprise 2,2,6,6-tetramethyl-4-piperidine derivatives. When added to resins, these antimicrobial agents provide antimicrobial resin compositions, which in turn provide antimicrobial articles. These antimicrobial agents provide resins, synthetic fibers or the like with not only outstanding antimicrobial activity but also excellent heat resistance, weatherability and deterioration resistance without impairing the transparency and safety of these materials.
摘要:
A deodorant and antimicrobial composition comprises an oxide or hydroxide of an alkaline earth metal, hydrated silica, and a cationic surfactant. A deodorant and antimicrobial resin composition can be obtained using the deodorant and antimicrobial composition and a thermoplastic resin. This deodorant and antimicrobial resin composition can be molded or otherwise formed.
摘要:
A deodorant and antimicrobial dispersion is formed of a deodorant and antimicrobial component, a binder resin and an aqueous or oily liquid medium. The deodorant and antimicrobial component comprises an oxide or hydroxide of an alkaline earth metal, hydrated silica, and a cationic surfactant.
摘要:
An epoxy resin composition according to the present invention is one initiating cationic polymerization upon irradiation with energy rays. The epoxy resin composition is formed of at least bisphenol type epoxy resin (A) as an active ingredient, epoxy resin (B) shown in the following formula and cationic polymerization catalyst (C). The epoxy resin composition can improve the thermal resistance of the adhesive layer in an optical information recording medium, and the adhesive property of the adhesive layer is not lowered even if its hardness is increased or it is in high humidity. where R is n=1 to 4
摘要:
An optical recording medium is provided, in which there are few warps, and no corrosion in the recording film, even when the protective film of the optical recording medium is made thick. The optical recording medium includes a substrate 2, a recording film 3 formed on the substrate 2, and a protective film 4 formed on the recording film 3, and recording signals can be reproduced optically from the side of the protective film 4. The protective film 4 is a film obtained by curing with UV light irradiation a composition including a cationic polymerizable resin (A) and a cationic polymerization catalyst (B) at a ratio of 100:0.2 to 1.5 by weight. The protective film 4 has a thickness of 20 to 200 &mgr;m.
摘要:
A solvent-free photocurable resin composition is provided which can be applied to the surface of optical discs or the like to form a highly transparent protective film that can stably adhere to the surface and effectively protect the surface from scratches. The solvent-free photocurable resin composition contains a urethane(meth)acrylate oligomer, a trifunctional (meth)acrylic acid ester monomer, a photopolymerization initiator, and a dilution monomer. The dilution monomer contains a fluorine-based (meth)acrylic acid ester monomer having three or more fluorine atoms and a monofunctional or difunctional (meth)acrylic acid ester monomer in amounts of from 10 to 40 wt% and from 10 to 30 wt%, respectively.
摘要:
Compositions for protective films include inorganic microparticles dispersed in an acrylic radical-based binder resin. Binder resins are formed from binder monomers including base components, scratch-resistant components and diluent components. Diluent components include diluent monomers having principal chain structures including a functional group having a cyclic structure or a branched carbon chain structure.
摘要:
An optical recording medium comprises a substrate, a recording film formed on the substrate, and a protective film formed by applying and curing a protective film forming composition on the recording film, wherein the protective film forming composition comprises 60 to 85 wt % of trimethylolpropane triacrylate modified with ethylene oxide, and 25 to 65 parts by weight of tripropyleneglycol diacrylate per 100 parts by weight of the trimethylolpropane triacrylate modified with ethylene oxide.
摘要:
Provided is an aqueous liquid composition including a water-based medium containing water, a polymer having at least one type of groups selected from hydroxyl groups and amino groups, and phosphonobutanetricarboxylic acid. The polymer is at least one polymer selected from the group consisting of a polysaccharide, polyamino acid, polyvinyl alcohol, polyallylamine, polyvinylamine, a polyamidine, a polyethylenimine, and their derivatives.
