摘要: A container for curable cyanoacrylate composition comprising: a reservoir for holding curable cyanoacrylate composition, the reservoir having an outlet through which the curable cyanoacrylate composition can be dispensed; the reservoir being defined by walls of plastics material, the plastics material being formed by a polymer material that is transmissive to both visible light and UV light; and a UV blocking agent dispersed in the plastics material the UV blocking agent comprising at least one benzotriazole; the walls of the container being transmissive to visible light and non-transmissive to UV light. Curable cyanoacrylate compositions held within such a container are thus storage stable in ambient conditions and yet the curable cyanoacrylate compositions can be seen through the walls of the container. A pack comprising the container and a curable cyanoacrylate composition is also described.

摘要: Compositions, laminates, films and/or composites made from thermoplastic polymers, such as thermoplastic polyurethane (TPU) are described. The films have one or more optical layers made from materials that allow the transmission of visible light and reflect or absorb UV light. An optical film is made from one or more TPU resins including a first UV absorber of the benzotriazole family or the triazin family, a light stabilizer, and a second UV absorber selected from a group consisting of benzotriazoles, benzophenones, triazin or benzylidene malonate. The second UV absorber may be present in a base resin combined with the TPU resin. The optical film is capable of blocking at least 99% of light having a wavelength

摘要: A method of producing an adhesive resin includes: a heating and kneading step of kneading a mixture containing a ring structure-containing hydrocarbon resin, an adhesive functional group-containing compound, and a peroxide while heating the mixture to obtain a heated and kneaded product; and a cooling and kneading step, performed in succession to the heating and kneading step, of kneading the heated and kneaded product while cooling the heated and kneaded product to obtain a cooled and kneaded product. The adhesive resin has a yellowness index (Yi) of 3.0 or less when 0.8 parts by mass of 2-(5-chloro-2-benzotriazolyl)-6-tert-butyl-p-cresol is added to 100 parts by mass of the adhesive resin.

摘要: A class of antioxidant compositions include benzotriazole phenolate salts with substituents either ortho to the phenol hydroxide group and/or para to the phenol hydroxide group can be prepared from substituted benzotriazole phenols. The ortho substituent group can be a simple hydrocarbon, alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenolate to another benzotriazole phenolate group.

摘要: Provided are benzotriazole derivative compounds of the general formula that are novel compounds capable of strongly absorbing light in the ultraviolet range, particularly 300-330 nm, while strongly absorbing light in the visible light short-wavelength range up to around 450 nm and being used suitably as a light absorber having high light fastness with a light-blocking function over an extended period of time. Preferably, R1 is a hydrogen atom or alkyl group, R2 is a C1-8 alkyl group, R3 is a hydrogen atom, alkyl group, acryloyloxyalkyl group, or methacryloyloxyalkyl group.
