    • Adhesive sheets made by using an acrylic pressure-sensitive flame-retardant adhesive which is excellent in adhesion performances, such as a bonding power and a high-temperature holding power, and exhibits such self-extinguishing properties (i.e., flame retardance) as to extinguish itself in an instant. They can be produced by preparing a photopolymerizable composition comprising (a) 100 parts by weight of a monomer mixture (or an oligomer mixture) comprising 70 to 100 wt.% of alkyl (meth)acrylates wherein the alkyl groups have 2 to 14 carbon atoms on an average and 30 to 0 wt.% of monoethylenically unsaturated monomers copolymerizable therewith, (b) 0.02 to 5 parts by weight of a polyfunctional (meth)acrylate as a cross-linking agent, (c) 0.01 to 5 parts by weight of a photopolymerization initiator, and (d) 10 to 180 parts by weight of a flame retardant having a melting point of 60 DEG C or above, preparing a pressure-sensitive flame-retardant adhesive containing this composition, and applying this adhesive to one or both surfaces of a substrate.

    • An ultraviolet ray-absorbing plastic plate which cuts off ultraviolet rays for extended periods of time to protect objects of art from ultraviolet rays and mechanical damage. The ultraviolet ray-absorbing plastic plate is obtained by polymerizing a polymerizable mixture which consists of a radical polymerizable compound containing at least one radical polymerizable monomer which has two or more alpha - beta unsaturated double bonds such as diethylene glycol bisallyl carbonate, a benzophenone-type ultraviolet ray-absorbing agent, and a radical polymerization initiator. The ultraviolet ray-absorbing plastic plate of the invention has a crosslinked structure, does not permit the ultraviolet ray-absorbing agent to bleed out of the surface of the plastic plate even after it has been used for extended periods of time, exhibits excellent properties such as great mechanical strength and heat resistance, and is transparent. Therefore, the plastic plate of the invention is used for protecting eyes and objects of art from the ultraviolet rays, i.e., used as an ultraviolet ray-shielding plate being installed in front of, for instance, a CRT display, as a member for protecting a picture frame, and as a member for cutting off ultraviolet rays generated from a source of light such as lighting apparatus.
    • 一种紫外线吸收塑料板,其长时间地切断紫外线以保护艺术品免受紫外线和机械损伤。 紫外线吸收塑料板通过聚合可聚合混合物而得到,该可聚合混合物由含有至少一种具有两个或更多个α-β不饱和双键的自由基聚合性单体组成的自由基聚合性化合物,例如二甘醇双烯丙基碳酸酯,二苯甲酮型 紫外线吸收剂和自由基聚合引发剂。 本发明的紫外线吸收性塑料板具有交联结构,即使在长时间使用后也不能使紫外线吸收剂从塑料板的表面渗出,显示出优异的性能 机械强度和耐热性好,透明。 因此,本发明的塑料板用于保护眼睛和物体免受紫外线的影响,即用作例如CRT显示器前面的紫外线屏蔽板作为保护用部件 相框,以及用于切断由照明装置等的光源产生的紫外线的部件。
