摘要： Described are photochromic epoxy resin coatings that meet commercially acceptable “cosmetic” standards for optical coatings. Also described are articles having such coatings. The coatings exhibit a Fischer microhardness of from 50 to 150 Newtons per mm2 and desirable photochromic properties, i.e., the formation of darker activated colors and faster rates of photochromic activation and fade when irradiated with ultraviolet light.

摘要： The present invention has an object to provide curatives for epoxy resins and curing accelerators for epoxy resins, which both have improved subliming and decomposing properties and which, when mixed with an epoxy resin, enable the mixture to be greatly improved in thermal stability that is extremely important for the control of a curing reaction and to have a prolonged pot life (stability as a one-pack mixture comprising the epoxy resin, curative, etc.) and improved curability at low temperatures. The curative is characterized by being a clathrate comprising a tetrakisphenol compound represented by a general formula [I]; wherein X represents (CH2)n, wherein n is 0, 1, 2 or 3, and R1 to R8 each represents hydrogen, a lower alkyl, optionally-substituted phenyl, halogeno or a lower alkoxy, and the curing accelerator is characterized by being a clathrate comprising a tetrakisphenol compound represented by the general formula [I] shown above and a compound accelerating the curing of a compound which reacts with the epoxy group of an epoxy resin to cure the resin.

摘要： The invention relates to a flame-retardant coating which forms an insulating layer and is based on substances which carbonize and form a foam layer in the event of a fire, on film-forming binders, on blowing agents and on customary auxiliaries and additives, wherein the blowing agent present comprises melamine polyphosphate. The novel flame-retardant coating which forms an insulating layer is particularly stable under tropical conditions (up to 100% rel. humidity, about 75° C.), i.e. it releases only an extremely small amount of NH3.
