Patent ID: 7820741

Claim:
A flame retardant adhesive composition comprising: (A) a halogen-free epoxy resin, (B) a carboxyl group-containing acrylic resin and/or a carboxyl group-containing acrylonitrile-butadiene rubber, (C) a curing agent, (E) a phosphate compound represented by a general formula (1) shown below and/or a phosphate compound represented by a general formula (3) shown below: [wherein, n represents a number from 1 to 100, X 1 represents either ammonia or a triazine derivative represented by a general formula (2) shown below: [wherein, Z 1 and Z 2 are the same or different, and each represent a group selected from the group consisting of groups represented by a formula: —NR 5 R 6 (wherein, R 5 and R 6 are the same or different, and each represent a hydrogen atom, a straight-chain or branched alkyl group of 1 to 6 carbon atoms, or a methylol group), a hydroxyl group, a mercapto group, straight-chain or branched alkyl groups of 1 to 10 carbon atoms, straight-chain or branched alkoxy groups of 1 to 10 carbon atoms, a phenyl group, and a vinyl group], and p is a number that satisfies: 0<p≦n+2], [wherein, r represents a number from 1 to 100, Y 1 represents a diamine represented by a formula: R 1 R 2 N(CH 2 ) m NR 3 R 4 (wherein, R 1 , R 2 , R 3 and R 4 each represent, independently, a hydrogen atom, or a straight-chain or branched alkyl group of 1 to 5 carbon atoms, and m represents an integer from 1 to 10), piperazine, or a diamine that contains a piperazine ring, and q is a number that satisfies: 0<q≦r+2], and (F) an ion scavenger and/or a heavy metal deactivator.
