<P>PROBLEM TO BE SOLVED: To provide a flame-retardant pressure-sensitive adhesive composition, preventing a flame retardant from being deposited on a pressure-sensitive adhesive layer surface, even when a large amount of the flame retardant is blended, and preventing a pressure-sensitive adhesive characteristic and a mechanical characteristic from being impaired, and a flame-retardant pressure-sensitive adhesive sheet using the same. <P>SOLUTION: The flame-retardant pressure-sensitive adhesive composition contains (A) a (meth)acrylic polymer comprising a copolymer of butyl acrylate and a monomer having a reactive functional group and/or an alkyl (meth)acrylate, (B) a phosphazene-based flame retardant, (C) phosphate-based flame retardant, (D) a crosslinking agent, and (E) an aromatic pressure-sensitive adhesiveness-imparting resin, a total blended amount of the (B) component and the (C) component is 60 to 350 pts.mass, per 100 pts.mass of the (A) component, and a blended ratio of the (B) component and the (C) component is within a range of 25:75 to 75:25 in mass ratio. <P>COPYRIGHT: (C)2013,JPO&INPIT |
