Abstract
Abstract A crosslinkable resin composition comprising (A) a polyethylene resin composition containing 0.1 to 10% by weight of a crosslinking agent and (B) a thermosetting resin composition selected from the group consisting of cyanate ester resin compositions, polyester resin compositions and epoxy resin compositions; said crosslinkable resin composition comprising (1) 95 to 5% by weight of the resin composition (A) and 5 to 95% by weight of the resin composition (B) when the resin composition (B) is a cyanate ester resin composition, and (2) 95 to 20% by weight of the resin composition (A) and 5 to 80% by weight of the resin composition (B) when the resin composition (B) is a polyester resin composition or an epoxy resin composition; and a method for producing a laminate using said composition.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
41 words
A crosslinkable resin composition comprising (A) 95 to 5% by weight of a polyethylene homopolymer resin composition containing 0.1 to 10% by weight of a crosslinking agent and (B) 5 to 95% by weight of a cyanate ester thermosetting resin composition.
Claim 2
Dependent Claim
41 words
A crosslinkable resin composition comprising (A) 95 to 5% by weight of a polyethylene homopolymer resin composition containing 0.1 to 10% by weight of a crosslinking agent and (B) 5 to 95% by weight of a cyanate ester thermosetting resin composition.
Claim 3
Dependent Claim
117 words
A composition of claim 1 wherein said cyanate ester thermosetting resin composition is selected from the group consisting of (i) a polyfunctional aromatic cyanate ester monomer of the formula R--O-C.tbd.N).sub.n wherein n is an integer of 2 to 5, and R is an aromatic organic group, the cyanate groups being bonded to an aromatic ring of said aromatic organic group, (ii) a homoprepolymer of (i), (iii) a coprepolymer of (i) and an amine, (iv) a mixture, or a preliminary reaction product, of (i), (ii) or (iii) with an organic compound having at least one maleimide group in the molecule, and (v) a mixture, or a preliminary reaction product, of (i), (ii), or (iii) with an epoxy resin.
Claim 4
Dependent Claim
69 words
In a method for producing a laminate which comprises consolidating a plurality of layers under heat and pressure, at least one of said layers being a prepreg sheet which is a sheet of a crosslinkable resin composition or a composite sheet obtained by bonding said sheet of said crosslinkable resin composition to a substrate, the improvement wherein said crosslinkable resin composition is a crosslinkable resin composition of claim 1.
Claim 5
Dependent Claim
30 words
A method of claim 3 which comprises stacking said sheet of said crosslinkable resin composition, a substrate and copper foil, and pressing the resultant assembly to form a copper-clad laminate.
Claim 6
Dependent Claim
24 words
A method of claim 3 which comprises stacking said composite sheet and copper foil, and pressing the resultant assembly to form a copper-clad laminate.
