Resin composition
There is provided a resin composition from a mixture including: (a) 30-80 weight % of at least one thermosetting resin; and (b) 20-70 weight % of at least one soluble polyimide resin. The resin composition can be used in electronics applications.
1 . A composition comprising:
(a) 2-20 wt. % of one or more thermosetting resins;
(b) 1-25 wt. % of one or more soluble polyimide resins;
(c) 35-80 wt. % on one or more inorganic particulate fillers; and
(d) 5-45 wt. % of one or more crosslinkers,
wherein the wt. % ranges are with respect to the total solid weight of the composition, wherein the thermosetting resins comprise at least one arylcyclobutene resin;
and the soluble polyimide resins are prepared from aromatic tetracarboxylic acid dianhydrides selected from the group consisting of 3,3′,4,4′-biphenyl tetracarboxylic dianhydride (BPDA), 4,4′-oxydiphthalic dianhydride (ODPA), 4,4′-bisphenol A dianhydride (BPADA) and 4,4′-(hexafluoro-isopropylidene) diphthalic anhydride (6FDA); and aromatic diamines selected from the group consisting of 2,2′-bis(trifluoromethyl) benzidine (TFMB) and 1,3-bis(3-aminophenoxy) benzene (APB-133).
2 . The composition of claim 1 , further comprising a solvent, wherein the solvent is 10-70 wt. % of the total composition.
3 . The composition of claim 2 , further comprising 0.5-10 wt. % of one or more adhesion promoters based on the total composition.
4 . The composition of claim 3 , wherein the one or more adhesion promoters is an organic nitrogen-containing phosphorous compound.
5 . The composition of claim 3 , further comprising one or more components selected from the group consisting of cyanate esters, allylic resins, butadiene resins, cyanurate, isocyanurate, and (meth)acrylate resins.
6 . The composition of claim 5 , wherein the one or more components comprises triallyl cyanurate and triallyl isocyanurate.

8 . The composition of claim 7 , wherein the triallyl cyanurate and triallyl isocyanurate are 20-30 wt. % of the total solid weight of the composition.
9 . The composition of claim 2 , wherein the one or more crosslinkers are maleimides.
10 . The composition of claim 9 , wherein the maleimides comprise one or more biphenyl groups.
11 . The composition of claim 10 , wherein the maleimides are 10-30 wt. % of the total solid weight of the composition.
12 . The composition of claim 11 , wherein the maleimides are 10-20 wt. % of the total solid weight of the composition.
13 . The composition of claim 2 , further comprising one or more additives selected from the group consisting of, organic fillers, plasticizers, adhesion promoters, metal passivating materials, flame retardants, and surface leveling agents.
14 . A surface-treated metallic foil, wherein at least one surface of the surface-treated metallic foil comprises a surface treatment comprising the composition of claim 2 .
