Claims
- 1. A hot melt adhesive composition consisting essentially of
- (A) 99 to 80 wt % of an ethylene-vinyl acetate copolymer,
- (B) 1 to 20 wt % of a monofunctional or polyfunctional cyanate ester compound having at least one cyanate group in the molecule, and
- (C) a monofunctional or polyfunctional maleimide compound or a cross-linking catalyst for the ethylene-vinyl acetate copolymer (A) in an amount of from 0.1 to 5% by weight based on the weight of the component (A) and the component (B).
- 2. The composition as claimed in claim 1, wherein the amount of the ethylene-vinyl acetate copolymer is 95 to 85 wt %.
- 3. The composition as claimed in claim 1, wherein the ethylene-vinyl acetate copolymer has a vinyl acetate content of 8 to 50 wt %.
- 4. The composition as claimed in claim 3, wherein the vinyl acetate content is 25 to 40 wt %.
- 5. The composition as claimed in claim 1, wherein the monofunctional or polyfunctional cyanate ester compound having at least one cyanate group in the molecule is represented by the formula
- R(OCN)m
- wherein m is an integer of 1 or more, R is an aromatic organic group, and the cyanate group is bonded to an aromatic ring of the aromatic organic group.
- 6. The composition as claimed in claim 1, wherein the monofunctional or polyfunctional maleimide compound is a compound having at least one N-maleimide group in the molecule.
- 7. The composition as claimed in claim 1, wherein the cross-linking catalyst for the ethylene-vinyl acetate copolymer is selected from the group consisting of an organic peroxide, sulfur and an organometallic salt.
