Abstract

Official abstract text for this publication.

The present disclosure discloses a resin composition, and a prepreg, a laminate and a printed circuit board containing the same. The resin composition comprises 100 parts by weight of a halogen-free epoxy resin, 11-37 parts by weight of an active ester resin, and 40-66 parts by weight of a compound represented by Formula (I), wherein n is 2-15; Ac represents an acetyl group. The prepreg, laminate and printed circuit board prepared from such resin composition have a low dielectric loss factor, good flame retardancy, and also have high interlaminar adhesion and a low CTE.

First claim

Opening claim text (preview).

1 . A resin composition, comprising: 100 parts by weight of a halogen-free epoxy resin, 11-37 parts by weight of an active ester resin, and 40-66 parts by weight of a compound represented by Formula (I), wherein n is 2-15; Ac represents an acetyl group. 2 . The resin composition claimed in claim 1 , wherein the halogen-free epoxy resin is selected from the group consisting of a biphenyl novolac epoxy resin, a DCPD novolac epoxy resin, an alkylene novolac epoxy resin, a bisphenol A novolac epoxy resin, a bisphenol AP epoxy resin, a bisphenol TMC epoxy resin, and combinations thereof. 3 . The resin composition claimed in claim 1 , wherein the active ester resin is a compound represented by Formula (II) wherein X represents a phenyl group or a naphthyl group; j is 0 or 1; k is 0 or 1; n is 0.25-1.25. 4 . The resin composition claimed in claim 1 , wherein the active ester resin has a number average molecular weight of 800 or less. 5 . The resin composition claimed in claim 1 , wherein the resin composition further comprises a cyanate ester or a prepolymer thereof. 6 . The resin composition claimed in claim 1 , wherein the resin composition further comprises a curing accelerator. 7 . The resin composition claimed in claim 1 , wherein the resin composition further comprises flame retardant salts. 8 . The resin composition claimed in claim 1 , wherein the resin composition further comprises a filler. 9 . A prepreg obtained by impregnating or coating a reinforcing material with the resin composition claimed in claim 1 and semi-curing the same. 10 . A laminate comprising at least one sheet of the prepreg claimed in claim 9 . 11 . A printed circuit board comprising at least one sheet of the prepreg claimed in claim 9 . 12 . A printed circuit board comprising at least one sheet of the laminate claimed in claim 10 .
