PHOTOPOLYMERIZABLE COMPOSITION, PRESSURE-SENSITIVE FLAME-RETARDANT ADHESIVE, AND ADHESIVE SHEETS |
摘要 |
<p>Adhesive sheets using an acrylic pressure-sensitive flame-retardant adhesive having excellent properties such as adhesive force and holding power at high temperature and also having a self fire-extinguishing property which instantaneously extinguishes fire, i.e., a flame-retardance, are provided. A photopolymerizable composition comprising a) 100 parts by weight of a monomer (or the oligomer thereof) comprising 70 to 100% by weight of a (meth)acrylic acid alkyl ester having on the average a carbon number of 2 to 14 in the alkyl group and 30 to 0% by weight of a monoethylenically unsaturated monomer copolymerizable with the ester, b) 0.02 to 5 parts by weight of a polyfunctional (meth)acrylate as a crosslinking 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 at least 60 DEG C is prepared, a pressure-sensitive flame-retardant adhesive is prepared from the photopolymerized product of the composition, and the adhesive is formed on one or both surfaces of a substrate.</p> |
