Abstract:
An epoxy resin curable composition for a prepreg, comprising the following components (A) to (E): (A): a polyamide compound having a structure derived from an aromatic diamine including a phenolic hydroxyl group, the aromatic diamine having the phenolic hydroxyl group in a position adjacent to an amino group; (B): an epoxy resin; (C): an epoxy resin curing agent; (D): a filler; and (E): a solvent.
Abstract:
PROBLEM TO BE SOLVED: To provide a thermosetting resin composition exhibiting an excellent adhesivity to silicon wafers after cured. SOLUTION: The adhesive resin composition for silicon wafers includes a compound having a urea structure in an amount that the urea structure portion of the compound accounts for 0.1-50 pts.mass to 100 pts.mass of an epoxy resin.

Abstract:
PROBLEM TO BE SOLVED: To provide a composite material having an epoxy resin adhesive layer at the interface of a polyimide layer and an epoxy resin layer. SOLUTION: The composite material is formed by laminating a layer (B) comprising a polyimide on a layer (A) comprising an epoxy resin curable composition containing a polyamide compound which has a structure having a phenolic hydroxyl group represented by the general formula (I) or the general formula (II). In the formulae (I) and (II), rings A and B are each a 6-18C arylene group or a 13-25C alkylidenediarylene group. COPYRIGHT: (C)2009,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To obtain a triazine-based aromatic phosphate compound that exhibits an excellent flame retardance with a small amount of addition without reducing physical properties such as resin strength, etc., when mixed with a synthetic resin. SOLUTION: The triazine-based aromatic phosphate compound is produced by a method for reacting 4-hydroxybenzonitrile in a methylene chloride solvent by using a trifluorosulfonic acid catalyst to produce a tris(hydroxyphenyl)triazine compound and reacting the tris(hydroxyphenyl)triazine compound with a diphenylphosphoric acid chloride compound.
