<P>PROBLEM TO BE SOLVED: To provide a thinned flame retardant adhesive sheet, which is an adhesive sheet having an adhesive layer on at least one surface of a base, has sufficient adhesive strength even when an adhesive layer is thinned and an adhesive that constitutes the adhesive layer contains a flame retardant, and has both excellent flame retardancy and adhesive strength. <P>SOLUTION: The flame-retardant adhesive sheet has an adhesive layer on at least one surface of the base, wherein the base has flame retardancy complying with VTM-0 in a test according to the UL94 specification; the thickness of the adhesive layer per surface is 0.6 μm or more and the total thickness of the adhesive layer is 7.0 μm or less; the adhesive that constitutes the adhesive layer contains (A) an acrylic copolymer, (B) a urethane resin, and (C) the flame retardant; and the content of (C) the flame retardant in the adhesive is 0.1 to 40 mass% and the value of [T/Wc] is 0.07 to 0.45, provided that Wc (mass%) is the content of (C) the flame retardant in the adhesive and T (μm) is the total thickness of the adhesive layer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
